Full textAbstract:
Seasonal floods that occur in residential areas affect the socio-economic conditions of the community which will gradually lead to a level of survival. Resilience occurs because of the encouragement of the community that exposed to flood disasters to absorb and overcome the disturbances and get recover to keep continue the life, including to the community who live in flood-prone settlements in Barabai District. This study aims to analyze the ability of community survival as resilience in flood-prone areas in Barabai District. The method used in this research is quantitative descriptive with scoring method whose assessment is based on the Resilience Radar index. This research asseses the social, economic, preparedness and physical dimensions. The results of the study found that the high-resilience element of the community resilience in Barabai is social dimension, and the low-resilience element is physical dimension. In aggregate, the community in flood-prone settlements in Barabai has a medium level of survival capability to flood disaster.

Full textAbstract:
The response of M. halmaturorum was measured to determine the ability of juvenile plants to survive flooding and to examine how this influenced plant growth. Seedlings and one- and two-year-old plants were flooded to 0% (control), 50% or 100% of their initial height for periods of three to 14 weeks, followed by an eight-week recovery period. Only 22% of seedlings survived five weeks of 100% coverage, but these died during the recovery period. The older plants survived the flooding treatments well, but as duration increased so survival through the recovery period declined. After 100% coverage for six weeks followed by the recovery period, only 29% survived. Stem linear extension rates corresponding to these survival rates were used to predict the survival of juvenile M. halmaturorum in Bool Lagoon, South Australia. The results showed that, with the current water regime, natural recruitment would occur only at the highest elevation but that this could be improved by planting older, taller plants at lower elevations. Indices of growth showed that flooded plants performed poorly compared with the controls as duration and percentage of coverage increased. The data suggested that coverage inhibited plant growth during the flood period, but there was a further, interactive response to duration that became apparent after the post-flood recovery period. An interpretation of these results is that M. halmaturorum in its juvenile stages is intermediate between a flood-sensitive and a flood-tolerant species because it is able to recover from short floods of three weeks or less but performs poorly if floods exceed six to nine weeks.

Full textAbstract:
The relationship between flooding, and the establishment and persistence of exotic species, is not well understood in highly variable dryland rivers. Increased moisture associated with floods is likely to stimulate establishment and growth of exotic plants, but floods may also act as a stress to exotic plants if floods last for weeks to months. This study examined how physical drivers of dryland rivers – flood inundation and geomorphology – influence the persistence of Xanthium occidentale Bertol. in the dryland Darling River, Australia. The distribution of X. occidentale was associated with flood-related moisture subsidy, moderated by channel geomorphology. Dead stalks and burrs on the ground occurred above the 8-m height of the previous flood. Adult and juvenile plants occurred below 8 m corresponding to smaller flood events. Flatter geomorphic units (floodplains and benches) contained more plants and burrs, whereas steeper geomorphic units (banks) did not retain burrs, limiting plant abundance. Flooding is not a stress to X. occidentale. A glasshouse experiment showed that flood durations of up to 40 days had minimal effect on the germination, survival and growth of X. occidentale burrs, seeds or seedlings. Weed management strategies for X. occidentale in dryland rivers could be enhanced by targeting periods following flooding when moisture availability is increased on the flatter geomorphic units in the river channel.

Full textAbstract:
The Bulgarian Black Sea coastal zone is relatively protected from sea floods. Only extreme meteorological events such as unusual storms can cause flooding of coastal areas. Crucial for the application of rapid methods for vulnerability assessment of coastal plant communities from flooding caused by unusual storms over the Bulgarian Black Sea Coast is to obtain experimental data for sea water flood resilience. This study aims to determine the plant species survival in simulated flooding experiments in order to identify sea water flood resilience of five plant species with conservation status: Centaurea arenaria M. Bieb. ex Willd., Crambe tataria Sebeok, Aurinia uechtritziana (Bornm.) Cullen & Dudley, Silene thymifolia Sm., and Stachys maritima Gouan. As a result of a simulated flooding experiment, Critical Decomposition Time (CDT) was obtained. The five species were within the most vulnerable group (CDT < 48 h). The CDT was significantly shorter than floods with a maximum duration for the Bulgarian Black Sea Coast. Only the values of the parameter beginning of decomposition of the leaves were accelerated by higher water temperatures. Other parameters were unrelated to different water temperatures. The investigated species have low survival rates and low degree of sea water flood resilience and their communities will not be able to recover after flooding with maximum duration within one vegetation season.

Full textAbstract:
Texasweed is an annual broadleaf plant belonging to the Euphorbiaceae family and is an emerging problem in southern U.S. rice fields. Field studies were conducted in 2008 and 2009 to study the effect of flood depth on Texasweed survival and growth. The trearments were five flood depths: 0, 10, 15, 20, and 30 cm and two Texasweed growth stages: two- to three-leaf stage and four- to five-leaf stage. The experiment was conducted in a completely randomized split-plot design with three replications. Flooding conditions were created by placing potted plants in 1.3 m by 0.7 m by 0.7 m polyvinyl chloride troughs. The effect of flood depth on Texasweed growth and fruit production was evaluated using ANOVA and regression analysis. Texasweed plants were able to survive in floods up to 30 cm; however, growth and fruit production were reduced. Increasing flood depths resulted in increased plant height and greater biomass allocation to stem. Texasweed plants produced adventitious roots and a thick spongy tissue, secondary aerenchyma, in the submerged roots and stem, which may play a role in its survival under flooded conditions. The recommended flood depth for rice in Louisiana is 5 to 10 cm. A 10-cm flood in the present study caused about 30 and 15% biomass reduction in two- to three-leaf and four- to five-leaf stage Texasweed, respectively. The results, thus, suggest that flooding alone may not be a viable option for Texasweed management in drill-seeded rice. However, appropriate manipulation of flooding could enhance the effectiveness of POST herbicides. This aspect needs further investigation.

Full textAbstract:
Since arbuscular–mycorrhizal (AM) fungi are aerobic, symbiosis was not considered significant under flooded conditions. However, AM colonization of wetland plants is now believed more common than previously thought. In the humid tropics, storms that result in standing water for 24 hours or less are common. Short-term floods, especially on sandy soils, may leach banded fertilizer, reducing uptake efficiency. Crops planted in flood prone areas are not normally enhanced with mycorrhizal mixes. However, mycorrhizal associations tolerant to wet conditions may improve nutrient uptake as plants recover from short-term flooding. Greenhouse studies were initiated to determine the effects of frequent short-term floods (two to four events) on mycorrhizal colonization and subsequent development in snap bean (Phaseolus vulgaris Phaseolus vulgaris L.) plants. Flooding produced no obvious long-term physical effects on plant shoots. In the first study, flooding did not affect survival of colonies established before the first flood event. Percent root colonization in flooded vs. nonflooded treatments was not significantly different at either 31 or 50 days after planting (DAP). As root length increased there was a concomitant increase in colonization so that percent colonization remained approximately the same in both flooded and nonflooded treatments. In the second study, three weekly floods beginning 13 DAP (cotyledon leaf open only) did not inhibit initial mycorrhizal colonization. Mycorrhizal associations should form with snap bean under conditions subject to short-term flooding. Additional research is needed to determine the efficacy of different mycorrhizal mixes under short-term flooded conditions in the field.

Full textAbstract:
The potential for enhancing flood tolerance of birches by using better adapted rootstock was evaluated. Survival, growth, and physiological responses were compared among flooded and nonflooded container-grown Japanese birch (Betula platyphylla var. japonica Hara. `Whitespire') trees grafted onto each of four rootstock: paper birch (B. papyrifera Marsh), European birch (B.pendula Roth.), river birch (B. nigra L.), and `Whitespire' Japanese birch. Separate studies were conducted in Fall 1991 and Spring 1992. Results showed no consistent differences in net photosynthesis (Pn) or survival among nonflooded plants regardless of rootstock or season, nor, were any symptoms of graft incompatibility evident. Flooding the root system for as long as 44 days revealed considerable differences among the four rootstock, with similar trends for fall and spring. Plants on river birch rootstock typically had one of the highest P rates and stomatal conductance (g,) and, in certain cases, greater mean shoot growth rates and survival of plants subjected to prolonged flooding. Although plants with European birch rootstock had survival rates similar to those of plants with river birch rootstock, plants on European birch rootstock had lower Pn under prolonged flooding, fewer late-formed roots, lower root-tip density after flooding, more abscissed leaves, and greater inhibition of shoot growth of plants flooded the previous fall. Paper and Japanese birch rootstock were most sensitive to flooding and had the lowest survival rate after flooding. However, plants on paper birch rootstock were the only plants whose Pn did not increase significantly when flooding ended; they had the most abscissed leaves during spring flooding and the greatest inhibition of shoot growth in the spring after flooding the previous fall. The four rootstock ranked from most to least flood tolerant were river > European > Japanese > paper.

Full textAbstract:
Flooding is one of the major harmful abiotic stresses in the low lying areas of Asia and crop losses due to submergence are considerably high. Along with plant breeding techniques, agronomic management options in general and nutrient management in particular should be taken into consideration. Response of Sub 1 and non-Sub1 cultivars of rice to post-flood nitrogen (N) management under variable flood water was compared at maximum tillering stage. Submergence tolerance on survival, leaf senescence, metabolic changes, and anti-oxidant enzymatic activities were evaluated. Sub1 cultivars proved their superiority over IR-20 in terms of significantly higher survival, anti-oxidant enzymes and lower metabolic changes. Turbid water resulted in lower survival because of poor light transmission, chlorophyll retention and silt deposition. Basal phosphorus reduced the elongation, senescence and ethylene accumulation. Post-flood foliar spray of urea substantially increased the chlorophyll, soluble sugars and extenuated ethylene accumulation resulting in significantly higher survival. These nutrient management options can provide opportunities for better survival and productivity even under turbid water, helping farmers to cope with the existing problems in flood-prone areas.

Full textAbstract:
The relationship between nest site characteristics and nest success during tidal flooding was studied in six New Jersey colonies of marsh-nesting common terns (Sterna hirundo). Most colonies were on high ground with a northeast water exposure, and almost all nests were on mats of dead vegetation. Terns nested on the thickest areas of the mats and, whether nesting on mats or on the ground, they selected nest sites with low vegetation density. The characteristics of successful nests differed with the height and date of the flood tide, and with wind direction. In the 1975 flood, nests on high ground were more successful, whereas nests in tall grass and on large mats successfully survived tidal flooding in 1976. Because grass height and ground height are negatively correlated in the marsh, it is difficult for the terns to maximize both characteristics when selecting a nest site. The large mats associated with flood survival in 1976 were also associated with higher prédation rates, indicating a further complication in selecting a safe nest site. Data from these floods were compared with floods studied by other researchers to further test whether certain nest site characteristics are associated with nest success in different types of floods.

Full textAbstract:
This thesis examines Oryx and Crake and The Year of the Flood, speculative fiction novels by Margaret Atwood. I argue that storytelling is a means of survival in both novels, since protagonists rely on telling their own stories in order to be able to deal with their situations of survivors of apocalypse. First, I discuss how storytelling works as a theme in both novels, adopting Linda Hucheon's and Patricia Waugh's considerations on fragmented narratives. Second, I articulate both novels self-awareness narratives with dystopian theory, based on the notions by Tom Moylam, drawing on his concept of critical dystopia. Finally, I consider the ways in which Atwood rewrites the traditional narrative of apocalypse in the two novels. In this thesis I propose a reading of Oryx and Crake and The Year of the Flood as counterpart novels in the sense that, when read together, they amplify the discussion of the dystopian scenario presented. Storytelling as survival resonates in the many narrative levels of both works and I argue that even though the connection between storytelling and survival is a common theme in the two texts, it is worked differently in each of them. Oryx and Crake presents a discussion on the impossibility of telling a story straightforwardly and on the consequences of a society which devalues storytelling. The Year of the Flood, in turn, explores storytelling as a means of conveying survival knowledge and as well the consequences, both positive and negative, of the sharing of experience through oral stories.A presente dissertação examina Oryx and Crake e The Year of the Flood, romances de ficção especulativa de Margaret Atwood. A proposta deste trabalho é a de que o ato de contar histórias funciona como uma forma de sobrevivência em ambos os romances, uma vez que seus protagonistas contam suas próprias histórias a fim de lidar com a situação de serem sobreviventes do apocalipse. Primeiramente, discuto como esse ato de contar histórias é tematizado nos dois romances, utilizando as considerações de Linda Hutcheon e Patricia Waugh sobre narrativas fragmentadas. A seguir, articulo as narrativas autoconscientes de ambos os romances com a teoria da distopia, baseando-me principalmente em Tom Moylan e seu conceito de distopia crítica. Finalmente, considero o modo como Atwood reescreve a narrativa apocalíptica tradicional nos dois romances em foco. Nessa dissertação, ainda proponho a leitura de Oryx and Crake e The Year of the Flood como romances que formam uma contraparte no sentido de que, quando lidos juntos, amplificam a discussão do cenário distópico apresentado. O ato de contar histórias como forma de sobrevivência está presente nos diversos níveis narrativos em ambos os textos. Argumento que, mesmo que a conexão entre contar histórias e sobrevivência seja um tema comum nas duas obras, essa relação é trabalhada diferentemente em cada uma delas. Oryx and Crake fomenta uma discussão sobre a impossibilidade de contar uma história neutra e as consequências de uma sociedade que desvaloriza o ato de contar histórias. The Year of the Flood, por outro lado, explora esse ato como um modo de transmitir conhecimento de sobrevivência, assim como as consequências, positivas e negativas, de compartilhar experiências por meio de narrativas orais.

Full textAbstract:
The concept of resilience is increasingly applied to policy-making. However, despite its widespread use, resilience remains poorly defined, open to multiple interpretations, and challenging to translate into practical policy instruments. Three particularly problematic aspects of resilience concern its rigid conceptualisation of adaptation and learning, its de-politicised interpretation of participatory decision-making, and the ill-defined role and relevance of social vulnerability indicators. My research analyses these three aspects within the context of flood risk management in the UK, which is uniquely suited to studying the practicability of a cross-disciplinary concept like resilience, because it connects issues of natural resource management, social planning, and disaster management. First, I analyse two case studies of experimental pilot projects in natural flood management. Through studying project reports, and interviewing stakeholders involved in project implementation, I determine whether the theorised learning-by-doing method in resilience is reflected in experiences from real experimental projects. Secondly, I use one of these case studies to map out the political structure of local participatory bodies in flood management, and also conduct a small survey of local community groups. The purpose of this second study is to determine if collaborative methods can indeed lead to a knowledge-driven policy process as envisioned in resilience literature. Lastly, I use statistical analysis to compare a traditional flood management model and a socio-economic model. The aim of the statistical modelling is to determine whether socio-economic factors are indeed useful for informing flooding policy, and whether they offer new insights not already being used in modern flood management. I find that resilience gives insufficient consideration to the importance of political constraints and economic trade-offs in policy-making, and that evidence for the usefulness of socio-economic factors is inconclusive. Future work could focus on further refining the statistical modelling to pinpoint empirically verifiable indicators of resilience.

Full textAbstract:
Prairie rivers of the Great Plains, USA, provide important habitat for the federally threatened piping plover (“plover”, Charadrius melodus). Plovers nest on open to sparsely vegetated river sandbars, and their demographic rates are closely linked to habitat availability and quality, as well as river flow. The Niobrara River in northern Nebraska has supported 22–41% of the state’s plovers since species listing in 1986, but the population and habitat are relatively understudied, and both have declined since 2010. The objectives of this study were to understand plover demography, habitat, and the role of the Niobrara in the regional plover population.
Periods of high river flow promote creation and maintenance of suitable sandbar nesting habitat, but increased river flow during the plover breeding season can decrease nest and chick survival. We estimated the effect of daily peak river flow on survival rates of 115 nests and 66 chicks on the Niobrara River, 2010–2016, using logistic exposure and Cormack-Jolly-Seber models, respectively. We monitored 1,874 banded hatch-year and adult birds across the regional population (Niobrara River, Lewis and Clark Lake, Gavins Point Reach segment of the Missouri River), and used multi-state mark-recapture models to estimate survival and inter-annual dispersal probabilities among sites relative to habitat availability. We developed land cover datasets from high-resolution aerial imagery to quantify suitable habitat and compare the relative effects of habitat characteristics on nest-site selection and nest success for a subset of years (2010, 2012, 2014, and 2016) using logistic regression models. We included data from a sympatric nester with similar nesting habitat needs, the interior least tern (“tern”, Sternula antillarum athalassos), to improve precision of our models. We compared 63 plover and 92 tern nests to 292 random unused points, and 73 successful (hatched ≥1 egg) to 79 failed nests.
Low nest and chick survival and high emigration from the Niobrara appear to be important factors contributing to population decline. Daily nest and chick survival were negatively related to river flow. Nest-site selection was based primarily on distance to the river bank (i.e., the nearest potential source of predators), yet flooding (eggs submerged or washed out of the nest bowl during increased river flow) caused at least as many nest failures as predation. Nests predominantly were surrounded by dry sand habitat, indicating some degree of flood avoidance, but were no farther from water than random, and drier nest sites were no less likely to fail. Dispersal occurred throughout the regional population, but plovers were more likely to leave the Niobrara than to enter it. Expansive flood-created sandbars on the Missouri River, concurrent with a trend towards more vegetated and saturated habitat on the Niobrara, may have drawn birds from the Niobrara population, especially those that dispersed to the Niobrara during sustained Missouri River flooding 2010–2011.
The outsized negative effect of flooding on nest success, the lack of protection afforded by dry sand nest sites, and selection for nesting habitat based more strongly on predator avoidance than flood avoidance suggest that plovers may have face more frequent and intense levels of breeding season flooding than is typical. Identifying and promoting the processes that contribute to creation and maintenance of high-elevation sandbars on the Niobrara is an important next step towards effective management of nesting birds.Master of Science

Full textAbstract:
Globally, riparian ecosystems are in decline due to anthropogenic modifications including damming, channelization and the conversion of the floodplain for human use.
These changes can profoundly affect riparian species as many have adapted to the historical dynamism of these ecosystems. On the managed Missouri River, an imperiled shorebird, the piping plover (Charadrius melodus) uses riverine sandbars to breed. From 2004 to 2009, due to limited breeding habitat and low population numbers, the U.S. Army Corps of Engineers constructed 255 ha of sandbar habitat to benefit piping plovers and least terns (Sternula antillarum). During the breeding seasons of 2010 and 2011, historically high flows resulted in the creation of 1,887 ha of suitable sandbar habitat. Our study compared the demographic response and the condition of piping plovers to these anthropogenic and natural habitat creation events.
From 2005–2014 we monitored 1,071 nests, and from those nests we uniquely banded 968 adults and 2,021 piping plover chicks. We obtained 405 egg (clutch) mass measurements, 1,285 mass measurements from 633 adults, and 7,093 mass measurements from 1,996 plover chicks resulting in 3,175 mass measurements from 654 broods of chicks. We also collected 3,347 invertebrate prey samples. We used a random effects logistic exposure model to estimate nest success, a random effects Cormack-Jolly-Seber model in RMARK to estimate pre-fledge chick survival and the
Barker model in RMARK to estimate hatch-year (HY) and after hatch-year (AHY) survival and fidelity to our study area. We then used estimates from these analyses to calculate reproductive output, reproductive output necessary for a stationary population, and population growth (λ). For adult condition and egg (clutch) mass we used generalized linear mixed regression, and for pre-fledge chick growth rates we used a modified Richard's model to estimate the effects of habitat type (pre- vs. post-flood). We also tested for differences in invertebrate prey abundance between habitat types using negative binomial regression.
Our results indicated that AHY survival varied throughout our study and was lowest during the flood (2010 and 2011). We found that nest success, pre-fledge chick survival, reproductive output, and HY survival and fidelity were consistently higher on the flood-created habitat than engineered habitat, leading to sustained population growth after the flooding, as compared to just one year of population growth prior to the flood. Unlike pre-flood engineered habitat, the demographic parameters we measured did not decrease as the post-flood habitat aged. These differences were related to increased sandbar habitat, low nesting densities, and decreased nest and chick predation on the post-flood habitat. Although we hypothesized that increased demographic rates would be reflected by increased piping plover condition following the flood, we found that our measured condition variables (adult mass, clutch mass, and pre-fledge chick growth rates) remained unchanged following the flood. We also found evidence that clutch mass, chick growth rates and invertebrate prey abundance decreased as the post-flood sandbar habitat aged. As the condition of individuals did not appear to contribute directly to the increased demographic rates following the flood, we suggest that the change in density-dependent predation pressure may explain the discrepancy. As many ecosystems have previously been altered, it's rare that ecologists have the opportunity to compare management practices with natural ecosystem processes. Results from this study suggest that management intervention may not be an equivalent substitute for natural ecosystem processes and provide insight on future management of riparian ecosystem.Master of Science

Full textAbstract:
In the wetter climates associated with the coastal forests of northwestern North America, coarse woody debris (CWD) accumulations in the form of snags, downed boles, and large branches can be large in natural forest ecosystems. Seedlings often regenerate on stumps and downed logs in the understory of old-growth coastal forests. The question remains though, whether CWD is a necessary component for seedling survival and growth in forests managed for commodity production.
This study addresses one concern of forest managers: is there an immediate nutritional or moisture supply advantage conferred by CWD for the survival and growth of seedlings in the coastal climate of British Columbia? We compared survival and growth of seedlings planted in decaying wood compared to non-woody humus forms and mineral soil under
heavy shade and full light conditions. Low light environments are of particular interest since reports of the strong association between CWD and regeneration has primarily referred to understory seedlings and saplings in old-growth forests.

Full textAbstract:
Complex measures for emergency survival of population in floods Emergency survival ranks among the main measures in the field of population protection, involving a complex of activities carried out to guarantee the survival of population affected by an extraordinary event or a situation of a crisis. It usually builds on an evacuation from the areas affected. This diploma thesis sets out to explain the emergency survival, and evaluate whether the current state of its safeguarding is sufficient, especially during floods. The first chapter contains the basic term, the individual measures and describes the floods including protection against them. Further it provides a brief list of legislation concerning these questions including the Population Protection Concept. The following chapters directly focus on the emergency survival plan as well as the flood plan, in which their individual parts are described. The outcomes compare the entire matter with the measures adopted during the floods in the municipality of Vodňany in 2009. The whole thesis is based on the hypothesis that safeguarding the emergency survival is sufficient.

AbstractThe impacts of flood on the Nigerian population over the years have been enormous. This is because the attendant associated risks such as destruction of lives and properties, livelihood displacement, and impoverishment of victims arising from increasing flood cases have constituted a threat to the citizens’ survival and therefore inform the attention the menace has drawn among scholars, policy analyst. This chapter has as its primary aim, a critical assessment of the impacts of government responses over the plight of victims of flooding in Nigeria over the years under review. Thus, special attention is given in this chapter to the various barriers or challenges facing government response to the plight of flood victims in Nigeria. Finally, some valuable steps, which if taken will reduce these barriers or challenges, are outlined. Though, the study adopted the use of secondary sources of data collection via content analysis, the experiences and knowledge gathered in this chapter will be strategically useful to people and organizations interested in the government of Nigeria’s response to the plight of flood victims, barriers inhibiting the success of fund utilization in reducing the suffering and impoverishment of the flood victims, number of deaths, and population displaced as a result.

Abstract This chapter details the development of elephant tourism in Thailand. Following a logging ban enacted by the government in 1989, in response to devastating floods and loss of life brought about by unsustainable logging practices, elephants used in logging and their mahouts suddenly found themselves unemployed. From positions of high esteem, some 2000 elephants and their mahouts were forced to resort to begging on the streets of Thailand, in order to survive. Seeing this as an opportunity, Thai entrepreneurs began to offer visits to old logging camps that had been turned into attractions for tourists, beginning the involvement of elephants in the tourism sector. The welfare of the elephants at this stage was at best a secondary concern for many of the camp owners and operators. The authors note however that this is now changing. Interestingly, for the elephants in Thailand, the improvements in their welfare resulted from the actions of travel trade associations such as ABTA (the Association of British Travel Agents), travel trade channel members, and specialist animal welfare and ethnic community NGOs.

The conclusion provides brief lessons about the Blockade and survival. First, unresolved legacies of the Blockade remained: rebuilding authority and infrastructure; aligning wartime adaptations (practices and habits) with postwar politics; facing the expanded shadow economy; dealing with the flood of civilians hoping to enter the city; and framing and integrating the Blockade experience into a postwar narratives and propaganda. Some commentary on Stalinism and Russian historiography is offered: in particular, the need to square the circle of the Stalinist cult and dictatorship with everyday practices, without dismissing or understating either. The conclusion ends with possible lessons about social theory. Institutions require more exploration, especially regarding fields and the role of anchors. Power and authority need refinement, especially regarding “compulsion.” Social distance, anchors, and empathy and emotion require far more serious research and inclusion into theoretical frameworks. And suffering demands more attention empirically and theoretically.

<em>Abstract</em>.—Larval fish assemblages are an important component of reservoir communities by providing an abundant prey source critical to the recruitment of predator species into recreational fisheries. We examined the composition, abundance, and length distribution of larval fish in several Nebraska flood-control reservoirs from 2000 to 2004 that were stocked with walleye <em>Sander vitreus </em>and experienced weather-related extirpations of gizzard shad <em>Dorosoma cepedianum</em>. Gizzard shad dominated the larval fish assemblages with a wide-ranging length distribution prior to extirpation. After extirpation, Centrarchidae species eventually filled the void with a smaller and truncated length-frequency distribution. Larval fish densities varied widely throughout the study period with fewer prey available to predators with gizzard shad present in the assemblages. The extirpation of gizzard shad elicited a significant change to the larval fish assemblages of these reservoirs but did not prohibit the survival of stocked walleye fingerlings.

Innovations in production technology and machinery increased efficiency and productivity but also introduced risk, especially if employees were given responsibilities for which they were not trained. Accidents that maimed employees and destroyed structures and equipment were commonplace. Recognizing and addressing risk were important to business survival. Risk also resided in environmental variability; flood and drought, hailstorms, high winds, and lightning could all affect grain production, river transport, water availability and quality, or distillery functions. Cattle and hogs in distillery feeding pens were susceptible to the same diseases that plagued the general livestock population, often with losses sufficient to force distillers into bankruptcy. Fires caused by mechanical failure, lightning, careless use of lanterns, or arson might destroy an entire distillery works. Insurers developed actuarial risk assessment techniques to reduce their vulnerability, and insurance premium rates forced distillers to consider building fire-resistant structures and increase the spacing between warehouses. This, in turn, changed the distilling landscape and introduced formal external controls into the distilling process.

This chapter focuses on Hurricane Agnes, which struck the United States in June of 1972 and affected the lives of tens of thousands of people from Florida to New York. The thirty-two trillion gallons of water that fell on New York and Pennsylvania caused devastation that left buildings and homes in ruins and property damage estimated to be in the billions of dollars. The flood also left some people homeless and some without electrical power, telephones, fresh drinking water, or sewers. Many were isolated from the outside world as roads and bridges collapsed or buckled due to flooding. Survival was the goal of the communities during the first seventy-two hours of the disaster. Political and economic recovery became the focus of civic leaders in the weeks after, but the trauma of that summer also called for psychological healing. Mired in mud and misery, bereft of property and employment, the people of New York and Pennsylvania looked to their local, state, and federal governments for help and answers.

Full textAbstract:
Experiments were conducted in cold conditions (5°C water temperature and 5°C air temperature) to assess the thermal protection of a 16-person, SOLAS approved, commercially available liferaft using a thermal manikin and human subjects. The comparison tests included four cases — 1. Inflated raft floor; dry clothing (Idry); 2. Inflated raft floor; wet clothing (Iwet); 3. Uninflated raft floor; dry clothing (Udry); 4. Uninflated raft floor; wet clothing (Uwet). The results demonstrated equivalence in insulation between human subjects and a thermal manikin for all cases of comparison (Idry: Manikin 0.236 (m2°C)/W versus Human 0.224 (m2°C)/W; Iwet: Manikin 0.146 (m2°C)/W versus Human 0.145 (m2°C)/W; Udry: Manikin 0.174 (m2°C)/W versus Human 0.185 (m2°C)/W; Uwet: Manikin 0.101 (m2°C)/W versus Human 0.116 (m2°C)/W). The results also showed the repeatability of the thermal manikin tests (0.177 (m2°C)/W versus 0.171 (m2°C)/W in Udry baseline case; and 0.101 (m2°C)/W versus 0.104 (m2°C)/W in Uwet baseline case). The results indicated that the insulation of a closed cell foam floor is comparable to an inflated floor (0.236 (m2°C)/W compared to 0.221 (m2°C)/W and 0.236 (m2°C)/W for closed foam floor from manufacturer A and B respectively). TPA provided considerable additional insulation than all baseline cases. A test with a human subject wearing a TPA in the Uwet case showed an improved insulation of 48% over the baseline case. TPA provided more additional insulation than a wet suit in all test cases except Udry case. In Uwet case, the worst test condition, the insulation obtained by sitting on a lifejacket (0.149 (m2°C)/W) is less than wearing a TPA (0.158 (m2°C)/W). Both of these are better than sitting directly on an uninflated floor (0.104 (m2°C)/W) or a closed cell foam floor (0.129 (m2°C)/W). There is a significant decrease in insulation value sitting in 10 cm of water (0.05 (m2°C)/W). Two human subject tests show an insulation value of 0.079 (m2°C)/W and 0.081 (m2°C)/W respectively. A liferaft occupant heat loss model was developed and integrated with Defense R&D Canada’s Cold Exposure Survival Model to predict survival time. For Uwet case, the worst test condition, the survival time is 32 hours and functional time is 24 hours for the experimental conditions.

Full textAbstract:
This paper addresses a major challenge facing deepwater production of oil and gas: how to assure continuous flow of product under the pressures and temperatures found on the ocean floor. Syntactic foam promises to overcome the limitations exhibited by conventional insulation materials in the past. New hybrid glass and polymer chemistries with improved “hot, wet” performance survive in conditions that were formerly thought impossible. This paper presents the latest laboratory test data on these new materials, and proposes models for predicting long-term performance.

Full textAbstract:
Abstract While the uncertainties associated with actual pipeline asset condition demand the use of probabilistic methodologies to assess the integrity of pipelines, a realistic and validated probabilistic method to demonstrate post-hydrostatic test (PHT) integrity has eluded the pipeline industry. Traditionally, deterministic methods grow a “just-surviving flaw” (JSF) under worst-case pressure cycling to predict the remaining life of the most severe imperfection which could have survived a high-pressure event, such as hydrostatic test. The deterministic analysis results in a JSF fatigue life but does not identify the likelihood that the flaw exists. Furthermore, identifying the most severe flaw is not intuitive and attempts to probabilistically model material variabilities have failed to match known historical PHT reliability. A pipeline operator has now developed a novel approach to the task of quantifying marginal pipeline reliability after hydrostatic tests. Rather than limiting random values to only material properties, potential defects are assigned sizes and pressure cycling values, randomly sampled from validated distributions of defect size and pressure cycling severity (equivalent to downstream location). The number of generated defects is determined by a validated defect density, and defect size remains limited to what could have physically survived the hydrostatic test. The question posed is no longer “what are possible sizes of JSF close to discharge pressure surviving to a specific time under known load conditions?”, but rather “what proportion of the pipeline segments with similar defect populations would survive to a specific time under known load conditions?”. This represents a fundamental paradigm shift away from considering only a worst-case scenario to the quantification of plausible pipeline health conditions. Monte Carlo simulation time is kept practical by using an equivalent load integral method to project crack growth. This proposed methodology was validated by applying it to a selection of pipeline segments with known historical fatigue failures following hydrostatic tests in order to quantify the predictability of each section’s reliability at the failure time. The initial validation of the method was found to reasonably predict the past incidents. This paper will discuss the methodology, input parameters including their distributions, methods for assigning defect size distributions and densities based on extrapolations of field nondestructive examination (NDE) and in-line inspection (ILI) data, and a minimum defect density floor established based on the PHT fatigue failure of a newly constructed pipeline. While this method originally targets PHT pipeline segments, the development of a similar method for pipelines managed exclusively by ILI data is under development. The largest potential flaw for ILI-managed assets is then dictated by what could have evaded ILI tool detection rather than what could have survived a hydrostatic test. Herein, the progress on this development and future suggested research will be provided.

Full textAbstract:
"Evacuation training is important as disaster education that covers how to survive disasters. However, traditional evacuation training does not provide realistic simulated evacuation experience (SEE). To provide the such, we developed game-based evacuation training (GBET), where trainees are required to reach a shelter in the real world within a time limit while making decisions against virtual disaster situations presented as digital contents (e.g. video and single-choice question) on GPS-enabled smartphones or tablets. However, the GBET was insufficient in the audiovisual reality. To provide a more realistic SEE, we created an evacuation training using scenario-based augmented reality (AR) game that integrates marker-based AR and scenariobased game. Although only applicable in indoor activities, the evacuation training (the extended GBET system) presents AR that expresses disaster situations (e.g. flood and fire) by superimposing threedimensional computer graphics onto the real-time view through a handheld head-mounted display."

Full textAbstract:
Manufacturing enterprises are facing a major challenge to improve their production efficiency in order to survive in a globally competitive market. There is an opportunity to develop and apply intelligent scheduling software tools to improve their productivity and profitability. We have developed a distributed dynamic manufacturing scheduling technology using intelligent software agents. This technology can well address dynamic changes and disturbances in the shop floor locally without disruptions to regular production — a problem that cannot be solved by traditional planning and scheduling systems because these changes and disturbances cannot be predicted in advance. It can significantly improve equipment utilization rates thereby improving the efficiency and productivity of manufacturing enterprises. We have developed software prototype systems within our research facilities. We are collaborating with industrial partners to validate the technology in industrial settings and are looking for a software company in the manufacturing sector to commercialize the technology.

Full textAbstract:
<p>Performance-Based Fire Engineering (PBFE) is gaining traction in the US, with the aim to provide safe, resilient and cost-effective design solutions for structural systems in our evolving communities. Steel-framed buildings with composite steel-concrete floors are widely used in practice and offer opportunities for achieving robust fire performance through PBFE. This paper demonstrates the design process, computational modeling approaches, and main assumptions for PBFE of steel-concrete composite buildings using a streamlined and systematic methodology. Performance expectations are explicitly spelled out at the outset of the process. A set of design fires are generated using zone models based on high percentiles of the fuel load. Then, the thermal-structural response is modeled using nonlinear finite element analyses. Design alternatives are evaluated against the predefined performance expectations. While the prescriptive code design does not survive until burnout, PBFE alternatives can survive the fire, adopting selected structural upgrades and an optimized allocation of the thermal insulation on the steel members. The activation of tensile membrane action in the fire-exposed composite floor is captured by the model. Single bay models are compared to full building models, showing the beneficial contribution of the system restraints provided steel mesh continuity is ensured over the girders. Thus, the single slab model provides conservative results at lesser computational cost. The full building model allows investigating robustness under extreme scenarios such as multi- compartment fires or multi-hazard scenarios with fire following a column loss. Adoption of this design process by structural fire engineers can lead to robust PBFE designs with explicit evaluation of the response under a range of extreme events, for a demonstrated performance level that is pre-agreed between the stakeholders.</p>

Full textAbstract:
Hurricanes, floods, tornados and earthquakes create natural disasters that can destroy homes, businesses and the natural environment. Such disasters can happen with little or no warning, leaving hundreds or even thousands of people without medical services, potable water, sanitation, communications and electrical services for up to several weeks. The 2004 hurricane season ravaged the State of Florida, U.S.A., with four major hurricanes within a 6-week timeframe. Over nine million people evacuated their homes and damage to property was extensive. One proactive strategy to minimize this type of destruction and disruption to lives is the implementation of disaster-resistant buildings that are functional and operational. This approach uses the best energy-efficient buildings, fortified to the latest codes, and incorporates renewable energy systems. Businesses, government facilities and homes benefit from using photovoltaics to power critical items. This concept is a mitigation tool to reduce damage and cost of the destructive forces of hurricanes and other disasters. This past season’s experience showed that buildings designed and built to the latest standards with photovoltaic and solar thermal systems survived with little damage and continued to perform after the storm passed. Even following a disaster, energy conservation and use of renewables promotes energy assurance while allowing occupants to maintain some resemblance of a normal life.

Full textAbstract:
Based on the shock damage propagation distances and the median fragility limit of the equipments, the NEI 07–13 employs the shock damage rules for determining the potential for affecting safe shutdown and fuel cooling equipments. However, the NEI 07–13 does not provide more detailed guidance for performing the shock damage assessments, because both the shock damage distances and the methodology for developing the median fragility limit are not provided in NEI 07–13. This paper discussed methodology developed for performing simplified assessments for shock effects considering the material nonlinearity of the impact zone and the soil-structure interaction. Three different models (i.e., linear model, nonlinear mode, and SSI model) were developed to calculate the in-structure shock response. The results of the linear model show the shock response due to aircraft impact would completely propagate from the center of initial impact zone and then along a structure pathway (e.g. wall, floor, basemat) to the in-structure without any energy dissipation. As a result, the in-structure shock response spectra are considerably higher than the spectra associated with the design-basis earthquake in the high frequency range. In order to reduce the shock effects on the in-structure safety-related systems and equipments, the material nonlinearity of the impact zone and the soil-structure interaction were incorporated in the dynamic analysis. The numerical results show that both the material nonlinearity and the soil-structure interaction would obviously absorb the energy of the shock waves, so the in-structure shock response spectra were reduced due to these two factors. Finally, the representative shock response spectra were compared with those used in the seismic margin assessment in order to assess specific equipment survival.

Full textAbstract:
Designs for offshore structures that will be deployed in arctic regions have to consider ice forces, which can be the governing design load. In shallow-water areas (< ∼100 m), fixed bottom caisson designs and artificial islands usually offer the best solutions. In deeper water, however, moored floating systems such as the ship-shaped Floating Production Unit (FPU), the Spar and the Single Column Floater (SCF™) are practical solutions. Even in shallower water where earthquakes are a threat, a moored floater can be a better option because of its ability to avoid seismic effects of the quake due to its suspension in the water above the sea floor. It is estimated that about 30% of the remaining oil and gas reserves lie in the arctic regions of the world. Special care has to be taken to design offshore platforms to survive these extreme arctic environments. Along with severe environmental conditions, there is a possibility of icebergs and multi-year ice sheets as well. A practical solution is to remove the floating structure in case of the expected loads on the structure exceed the maximum design loads. The platform can be brought back to location after the extreme environmental condition has passed. This paper describes a design for a disconnectable mooring system that comprises of external fairleads, submerged chain locker boxes and diverter units along with quick release mechanism and a single handling winch for each group of lines. The system works in tandem with the rig’s ROV and an anchor handling tugboat when connecting the system, while disconnection is automatic without any external assistance other than an emergency release signal. The paper provides the rationale for selecting this configuration based on its strength, redundancy requirements, quick disconnectable ability, without interfering with normal operation and presents a range of applications for this design.
