Abstract:
As a result of the considerable impacts of hydrological hazard on water resources, on natural environments and human activities, as well as on human health and safety, climate variability and climate change have become key issues for the research community. In fact, a warmer climate, with its heightened climate variability, will increase the risk of hydrological extreme phenomena, such as droughts and floods. The Special Issue “Hydrological Hazard: Analysis and Prevention” presents a collection of scientific contributions that provides a sample of the state-of-the-art and forefront research in this field. In particular, innovative modelling methods for flood hazards, regional flood and drought analysis, and the use of satellite and climate data for drought analysis were the main topics and practice targets that the papers published in this Special Issue aimed to address.

Abstract:
An index has been developed for the assessment of geographical distribution of susceptibility to hydrological hazards using easily available climate data. Catastrophe fuzzy theory and data clustering methods were used to avoid subjectivity in the estimation of the index of multiple climate indicators. The proposed index was used for the estimation of geographical distribution of hydrological hazard susceptibility index (HHSI) in Peninsular Malaysia using gauge-based, gridded rainfall and temperature data for the period 1948–2010. The results showed that the northeast regions of Peninsular Malaysia are more susceptible to hydrological hazard, which matches very well with the general conception of the hydrological hazard susceptible zones. Assessment of susceptibility for sliding different 30-year periods between 1950 and 2010 revealed that HHSI has increased in the south and decreased in the northeast of the peninsula. The decrease in temporal and spatial variability of rainfall in the northeast and the increase in other parts can become the causes of spatial changes in hazard susceptibility. The changes of HHSI in recent years compared to the base period revealed the increase of hazard susceptibility in the south in the range of 8.81% to 21.01%, while a significant decrease (>−31.84%) was observed in the northeast.

Abstract:
Geo-hydrological risk reduction policies are becoming a critical challenge for environmental sustainability, both at the national and international levels. The reason is twofold: On the one hand, climate change has increase rainfall frequency and intensity, while on the other, reckless urban expansion has increased exposure to such hazards over time. Italy is a country that is very vulnerable to flood and landslide hazard; the city of Genoa, which, in recent decades, has been frequently hit by severe floods, has risen to symbolize Italian geo-hydrological risk. Recent studies on Genoa’s geo-hydrological hazard have focused on the analysis of hydro-geomorphological features of the Bisagno stream basin, yet their main focus was on hazard control. Very little research has been done to enhance the understanding of the source of risk in such catchments. This paper presents a study on the increased urban exposure and vulnerability to geo-hydrological hazard along the Bisagno stream catchment area over the last 200 years. Morphometric analyses were coupled with historical documents showing the evolution of the urban layout in this area. The results show that the “Bisagno Master Plan”, a territorial planning strategy aimed at reducing geo-hydrological hazard and risk, has not produced the expected benefits. In spite of the plan, critical changes in land use and the hydrographic network, along with uncontrolled anthropization of the Genoa metropolitan area, has continued over the last two decades.

Snow metamorphism is revealed to be of minor importance in the observed events. The monitoring of water-pressure development in a saturated snow cover demonstrates that preferred release areas are within low-gradient valley sections, where meltwater inflow is higher than outflow.Slushflows consist of mudflow-like flowage of water-saturated snow along stream courses. They represent transitional processes between fluvial floods and avalanches. On the other hand, they possess unique characteristics concerning release and movement.

Abstract:
Abstract A method for supporting an operational regional risk and vulnerability analysis for hydrological hazards is suggested and applied in the Island of Cyprus. The method aggregates the output of a hydrological flow model forced by observed temperatures and precipitations, with observed discharge data. A scheme supported by observed discharge is applied for model calibration. A comparison of different calibration schemes indicated that the same model parameters can be used for the entire country. In addition, it was demonstrated that, for operational purposes, it is sufficient to rely on a few stations. Model parameters were adjusted to account for land use and thus for vulnerability of elements at risk by comparing observed and simulated flow patterns, using all components of the hydrological model. The results can be used for regional risk and vulnerability analysis in order to increase the resilience of the affected population.

Abstract:
Urban floods are detrimental to societies, and flood mapping techniques provide essential support for decision-making on the better management of flood risks. This study presents a GIS-based flood characterization methodology for the rapid and efficient identification of urban flood-prone areas, which is especially relevant for large-scale flood hazards and emergency assessments for data-scarce studies. The results suggested that optimal flood mapping was achieved by adopting the median values of the thresholds for local depression extraction, the topographic wetness index (TWI) and aggregation analyses. This study showed the constraints of the depression extraction and TWI methods and proposed a methodology to improve the performance. A new performance indicator was further introduced to improve the evaluation ability of hazard mapping. It was shown that the developed methodology has a much lower demand on the data and computation efforts in comparison to the traditional two-dimensional models and, meanwhile, provides relatively accurate and robust assessments of flood hazards.

Abstract:
In Sahelian countries, a vast number of people are still affected every year by flood despite the efforts to prevent or mitigate these catastrophic events. This phenomenon is exacerbated by the incessant population growth and the increase of extreme natural events. Hence, the development of flood management strategies such as flood hazard mapping and Early Warning Systems has become a crucial objective for the affected nations. This study presents a comprehensive hazard assessment of the Nigerien reach of the Sirba River, the main tributary Middle Niger River. Hazard thresholds were defined both on hydrological analysis and field effects, according to national guidelines. Non-stationary analyses were carried out to consider changes in the hydrological behavior of the Sirba basin over time. Data from topographical land surveys and discharge gauges collected during the 2018 dry and wet seasons were used to implement the hydraulic numerical model of the analyzed reach. The use of the proposed hydraulic model allowed the delineation of flood hazard maps as well the calculation of the flood propagation time from the upstream hydrometric station and the validation of the rating curves of the two gauging sites. These significative outcomes will allow the implementation of the Early Warning System for the river flood hazard and risk reduction plans preparation for each settlement.

This research presents the numerical simulation to reproduce the transport and deposition processes of the sludge flow on March 15, 2017, strongly impacting the town of Pampapacta in Punta Hermosa-Peru.The debris flow initiation process in the basin was represented by hydrographs obtained from the estimated volumes of stormwater runoff and solid materials. The sludge flow was modeled in Flo2D to calculate hazard maps with the discharge event and others with different return periods.The numerical simulation results show acceptable results in relation to what happened. The model used to assess the hazard due to debris flow can predict and delineate, with acceptable precision, potentially hazardous areas for a landslide. The application of the proposed methodology to assess the hazard of disasters due to debris flows in basins and streams is useful to understand the extent of the impact of the mud flow during extreme weather events, as well as to develop emergency plans and formulate disaster policies.

Abstract:
Le tiers de la population mondiale, vit dans des espaces où les risques potentiels sont liés plus ou moins directement à la nature ; Les inondations, sont responsables de plus de la moitié des risques dommageables. À l’instar le risque inondation affecte les villes marocaines et plus particulièrement celles situées sur les piedmonts dir. Les agglomérations de dir de Béni Mellal sont très menacée par les inondations. Ces catastrophes sont le fait de crues-éclair (flash flood) trouvant leur origine dans la structure des précipitations (intensités remarquables) et une topographie propice à la concentration des écoulements sur de petits bassins versants de forte pente.Ce travail est une contribution opérationnelle à la connaissance du phénomène « crue-éclair » affectant les agglomérations du "dir" de Béni-Mellal dont l’objectif est l’amélioration de la résilience du "dir" de l’Atlas de Béni-Mellal face aux inondations et aux "crues-éclair". À cause de l’absence des stations hydro pluviométriques, est vue la spécificité de dire comme une zone de transition, la démarche élaborée repose sur une étude fine des deux facteurs du risque, l’aléa et la vulnérabilité, sur des bassins versants représentatifs du domaine du dir de Béni Mellal. Notre approche, que l’on peut qualifier "hydrologique intégrée" considère l’aléa comme une solidarité hydrologique entre l’amont et l’aval ou plutôt la dépendance de l’aval vis-à-vis de l’amont. La gestion des risques dans le dir de Béni-Mellal, demande donc l’intégration des techniques hydrologiques modélisatrices et l’association des mesures non structurelles telles que, la conscience du risque, la réduction de la vulnérabilité, la maîtrise de l’occupation du sol, surtout la dynamique urbaine. Les solutions adoptées doivent être cohérentes entre elles. A cet égard, notre méthodologie s’articule sur la valorisation de données multi-sources. Elle s’appuie, d’un côté, sur une approche de l’hydrologie classique, qui consiste en l’étude analytique de « l’aléa historique » et l’étude hydrométrique dont les données hydrométriques et pluviométriques produites, seront utilisées pour la caractérisation de « l’aléa » et des crues torrentielles. Une approche hydrologique modélisatrice où les résultats seront utilisés pour la calibration et la validation d’une modélisation hydraulique et pour la production des cartes de risques. D’un autre côté, elle vise à intégrer le contexte socio-économique et cultuel, le degré d’organisation de l’occupation du sol, et les politiques publiques de la gestion des risques…etc
One-third of the world's population lives in areas where potential risks are more or less directly related to nature. Floods are responsible for more than half of the damaging risks. Like other countries, the flood risk affects the Moroccan cities and especially those located on the piedmonts. For instance, the agglomerations of Béni Mellal piedmonts are very threatened by floods. These disasters are the result of flash floods originating principally from a changing rainfall pattern (remarkable intensities) and a favorable topography conductive to the concentration of the flows on small watersheds of steep slope.This study is an operational contribution to the knowledge of the "flood-lightning" phenomenon that is affecting the agglomerations of the "piedmont " of Beni-Mellal. Its objective is to identify the resilience of the Atlas “piedmont” of Beni-Mellal in the face of floods and "flash floods".Because of the absence of hydro-rainfall stations, and the specificity of the study area considered as being a transition zone, the approach developed is based on a detailed study taking into account two risk factors, namely the hazard and the vulnerability..Our approach, which can be described as "an integrated hydrological approach" considers the hazard as a hydrological solidarity between upstream and downstream or rather the dependence of downstream towards the upstream. Therefore, risk management in the piedmonts of Béni-Mellalrequires the integration of modeling hydrological techniques and the association of non-structural measures such as, risk awareness, vulnerability reduction, controlof soil occupation, especially urban dynamics. For this reason, the adopted solutions a must be coherent with each other. In this respect, our methodology is based on the valuation of multi-source data. It relie, on one hand, on a classical hydrology approach, which consists of the analytical study of "historical hazard"and the hydrometric study whose hydrometric and rainfall data will be used for the analysis. Characterization of "hazard" and flashfloods events (The results of this modeling hydrological approach will be used for the calibration and validation of hydraulic modeling and for the elaboration of risk maps. On the other hand, it aims at integrating the socio-economic and cultural context, the degree of organization of the occupation of the ground, and the public policies of the risk management ... etc

Abstract:
O aumento da ocorrência de desastres hidrológicos relacionados a inundações bruscas tem recebido maior atenção dos diversos órgãos em suas diferentes escalas, com o objetivo de reduzir ao máximo suas causas. Justamente por isso, as medidas não estruturais são medidas de extrema importância na prevenção de tais desastres. Uma dessas medidas deve ser o mapeamento de áreas de perigo de inundações. Portanto, o objetivo do presente trabalho foi propor e avaliar o perigo de inundações bruscas por meio de modelagem hidrogeomorfológica na bacia do arroio Forromeco-RS. Para isso, foi utilizado o modelo CAESAR-LISFLOOD, para representar os processos hidrológicos em escala de bacia e canal. Em escala de bacia foram gerados hidrogramas a partir da criação de chuvas de projeto para diferentes tempos de retorno (TR), considerando como base o maior evento registrado nessa bacia associado a um TR de 22 anos. Esses hidrogramas foram utilizados nas simulações em escala de canal para gerar os diferentes mapas de inundação em termos de profundidade e velocidade do fluxo da água. Para analisar as áreas de perigo de inundação, foram determinados os índices de perigo (IP) associados aos diferentes TR, a partir da profundidade e a velocidade d’água. Através das análises do resultado de IP foi criado o mapeamento final de perigo associado a três tempos de retorno (5, 22, e 100 anos). Além disso, estabeleceu-se três zonas para identificar os níveis de perigo, considerando o cenário mais crítico dos três mapas. Os resultados mostraram que a maior área inundada se encontra em alto perigo, ocupando 77% da área total, o que significa que as pessoas que moram nessa região estão em perigo tanto em casa, como fora delas. Ao mesmo tempo as construções estão em alta possiblidade de serem danificadas.
The increase in the occurrence of hydrological disasters related to flash floods has begun to be more important for several organs at different scales in order to reduce their magnitude and frequency as much as possible. Precisely because of it, non-structural measures are extremely important measures for preventing such disasters. One of these important measures might be the mapping of flood hazard areas. Therefore, the objective of the present work was to propose and evaluate the flash flood hazard by means of hydrogeomorphic modeling of the Forromeco river basin, Rio Grande do Sul state. Thus, the CAESAR-LISFLOOD model was used to represent the hydrological processes at basin and channel scale. At basin scale hydrographs were generated from the creation of hyetographs for different return periods (RP), considering the largest event recorded in this basin. These hydrographs were used in the channel scale simulations to generate the different flood maps in terms of depth and velocity of water flow. In order to analyze the flood hazard areas, the hazard indexes (HI) associated with the different RPs were determined from the depth and water velocity. Through the IP analysis, the final hazard mapping associated with three RPs (5, 22, and 100 years) was created. In addition, three zones were established to identify the hazard levels, considering the most critical scenario of the three maps. The results showed that the largest flood area is in high degree hazard, occupying 77% of the total area. It indicates that people are in danger both inside and outside houses. At the same time buildings are in high possibility of being damaged.

Abstract:
La ville de Toliara qui se trouve à l’exutoire du bassin de Fiherenana (Madagascar) est soumise chaque année aux aléas inondations. Les enjeux sont donc d'une importance majeure dans cette région. Cette étude débute par l’analyse de l’aléa avec les données hydro climatiques existantes. On cherche alors à déterminer les tendances en utilisant des modèles statistiques basés sur les séries temporelles. Une méthode de reconstitution des données manquantes est alors proposée. Ensuite, deux approches sont menées afin d’évaluer la vulnérabilité de la ville de Toliara et des villages alentours : une approche statique, à partir de relevés de terrain et de l’utilisation d’un système d’information géographique (SIG) ; et une autre avec l'utilisation d'un modèle multi-agents (SMA). La première étape est la cartographie d’un indicateur de vulnérabilité qui est l’agencement de plusieurs critères statiques propre à chaque maison comme la hauteur d’eau potentielle ou la typologie architecturale. La deuxième partie mettra en scène des agents afin de simuler un évènement catastrophique (montée des eaux et évacuation en simultanée). On cherche à savoir quelles sont les chances pour que les occupants d’une habitation puissent sortir indemne d’une inondation, en comparant divers paramètres et scénarios afin d’évaluer le degré de vulnérabilité de chaque ménage. Certains scénarios prennent en compte l’effet de certaines prises de décisions (Informations, sensibilisations etc.). Les indicateurs et les simulations permettent alors de mieux appréhender les risques inondations afin d’être une aide à la gestion des crises
Hydrological risks are recurrent on the Fiherenana watershed - Madagascar. The city of Toliara, which is located at the outlet of the river basin, is subject each year to hurricane hazards and floods. The stakes are of major importance in this part of the island. This study begins with the analysis of hazard by collecting all existing hydro-climatic data on the catchment. It then seeks to determine trends, despite the significant lack of data, using statistical models (time series). Then, two approaches are used to assess the vulnerability of the city of Toliara and its surrounding villages. First, a static approach, from surveys of land and the use of GIS are conducted. Then, the second method is based on a multi-agent model. The first step is the mapping of a microscale vulnerability index which is an arrangement of several static criteria. For each House, there are several criteria of vulnerability such as potential water depth or architectural typology. As for the second part, scenes of agents are simulated in order to evaluate the degree of housing vulnerability to flooding. The model aims to estimate the chances of the occupants to escape from a catastrophic flood. For this purpose, we compare various settings and scenarios, some of which are conducted to take into account the effect of various decisions made by the responsible entities (awareness campaign etc.). The simulation consists of two essential parts: the simulation of the rise of water and the simulation of the behaviour of the people facing the occurence of hazard. Indicators and simulations allow to better understand the risks in order to help crisis management. Key Words: Hy

O recente aumento do número de inundações e movimentos de massa na região densamente povoada no sudeste do Brasil, o presente estudo analisa as alterações espaciais e temporais na precipitação durante o período de 1978-2014, nas regiões montanhosas dos estados brasileiros do Rio de Janeiro e Santa Catarina. Avaliou-se a presença de tendência nas series sazonais, anuais e do conjunto de índices extremos de precipitação onde foi usado o software Rclimdex. As series são calculados a partir das series precipitação diária. Com base nos resultados observou-se que nas escalas anuais e sazonais se tem um aumento de precipitação, exceto para a temporada de inverno na região montanhosa de Rio de Janeiro. Além disso, foram encontradas de mudanças abrutas em diferentes anos para as séries de tempo analisadas, diferenças espaciais nas tendências em estações individuais e tendências associadas com elevação sugerem que apesar da proximidade destas duas regiões, os impactos do clima não são uniformes em todo o sudeste do Brasil. Os mecanismos de clima responsáveis pelas tendências de precipitação observada são identificados, mas trabalho adicional é necessário para isolar as causas. Por outro lado, o número de desastres naturais de tipo hidrológico como os movimentos de massa/enchentes estão aumentando. Este tipo desastre mostrou correlações positivas significativas com os índices 1-day (máximo de precipitação anual em um dia) e o 5-dias (máximo de precipitação anual em cinco dias consecutivos), sendo assim índices que podem ser úteis indicadores de eventos de risco hidrológicos para estas regiões.
In order to understand the rising number of flash floods and mass movements in the densely populated region of southeastern Brazil, this study analyzes the spatial and temporal changes in precipitation from 1978 to 2014. We focus on the sensitivity of mountainous regions, specifically the Rio de Janeiro (RJMR) and Santa Catarina (SCMR) regions. Daily rainfall observations are aggregated into annual and seasonal indices, and RClimdex is used to evaluate a suite of precipitation and extreme event indices. Results show positive annual and seasonal precipitation trends during all seasons except for the winter season in the RJMR. Diverse change points in their time series, spatial differences in the trends at individual stations, and trends associated with elevation suggest that despite the close proximity of these two regions, climate impacts are not uniform across all of southeastern Brazil. Climate mechanisms responsible for the observed precipitation trends are identified, but additional work is needed to isolate the causes. Statistically significant positive correlations are discovered between mass movements/flash floods events and annual maximum 1–day and 5–day consecutive precipitation, and these indices may be useful indicators of natural hazard events for this region.

The City of Manhattan, Kansas is looking for possible solutions to mitigate flooding along Wildcat Creek within the Wildcat Creek Watershed. Recent flooding has caused substantial property damage. The project presented here brings recreation into the community by designing a golf course in a location along Wildcat Creek that addresses flooding issues, increases infiltration, and improves water quality. The golf industry has a long way to go to become more sustainable. The world is facing many challenges related to water and hydrology. Much of the opposition towards the golf industry is because critics see it as environmentally unfriendly. Golf has the potential to become a catalyst for change in the way we design and develop the landscape around us. The golf industry can become a leader in sustainable design while taking on hydrological concerns within the community. This project demonstrates the application of a golf course to help mitigate flooding along Wildcat Creek with the use of vulnerability and suitability analysis as a guide to site selection. This method of analysis illustrates the process of identifying and protecting areas vulnerable to degradation by designing a golf course in a suitable location to utilize water hazards to store flood water, provide more floodplain access to effectively increase infiltration capacity, reduce runoff rates, and improve water quality. The report explains the relationship between golf course design and environmental practices as they relate to hydrology on a theoretical site in Manhattan, Kansas. By integrating golf course design theory and environmentally sound stormwater management practices, water hazards on the golf course can become the fundamental elements used in strategizing the design of the golf course. A conceptual plan was created to maximize the infiltration capacity of the site as well as allow increased floodplain access, and provide a place to store flood water. A golf course can then be properly sited and designed hydrologically around the use of water hazards to help reduce flooding and improve water quality within the watershed.

Abstract:
The aim of this research is to assess hazards and risks associated with flooding in the city of Juárez, northern México, where there is a flood threat from active alluvial fans from mountains to the southwest and from the Rio Grande (Bravo River) to the northwest forming the northeast border of the city. Aims of this Ph.D. were addressed processing a digital elevation model (DEM) of the study area in a GIS platform to define the several alluvial fans, and thus to examine their history and palaeohydrology. Three OSL dates in the youngest parts of the fans show ages ranging from 74 - 31 ka. However, the fans were subsequently incised, broadly correlating with later Pleistocene to Holocene processes upstream, published in literature, in New México. These changes are not obviously linked to glacial-interglacial cycles, and there is indication of local controls of interplay of climate and topography, for which this work is a preliminary study. The flood threat to Juárez was addressed by using a classification of the uneven topography of the eroded alluvial fans, plus the Bravo River flood plain, into basins and subbasins. Field and laboratory work was used to define litho-facies of soils and rocks, location of structures such as, topographic and hydrologic apex and drainage system in the fans. The data were then used in association with published information on the parameters of the basins and sub-basins provided in published documents from the Mexican authorities to make flood models of the area, using standard models of HEC-HMS and HEC-RAS methods widely applied in semi-arid regions. The result was estimation of the ability of existing flood defences to resist high-flow floods that may be expected in upcoming decades. The modelling predicts that only a small number of the existing defences will hold in a catastrophic 1:100-year flood, and that substantial parts of the city are in considerable danger. Such results are important in relation to the expanded and dense population in Juárez, which is concentrated mostly on the most active part of the flooding system, the Colorado Fan, which is the subject of a focussed secondary study of vulnerability mapping. The map reveals that areas of the city of low socioeconomic development are under the greatest threat. Therefore there is a need for reconsideration of the city's flood planning, and remediation, plus the application of enforcements of areas which should not be built on, because of the threats.

Abstract:
AbstractClimate affects the quantity of soil moisture within the surface of the earth and this is obtained by affecting the amount of radon flux density escaping from the land surface. This chapter contains the evaluation of climate change conditions as it affects the variability of soil water for the purpose of estimating the health effects of radon flux density within Ogbomoso metropolis. The simulated soil moisture content around Ogbomoso was done for a period of 34 years using the hydrological model, Soil Water Assessment Tool (SWAT). The calibration and validation of the SWAT model was done using the daily observed soil moisture content. The simulated daily soil moisture within Ogbomoso showed good performance when calibrated and validated. A 20 years prediction of the daily soil moisture content was done using the SWAT model. The estimation of the radon flux density for the study area was obtained using the simulated soil temperature and soil moisture from the SWAT model. In this chapter, the UNSCEAR radon flux formula was used for the radon flux estimate. The result showed that the UNSCEAR radon flux formula performed well in estimating the radon flux density in the study area. The mean value of the radon flux density of 15.09 mBqm−2 s−1 falls below the estimated world average of 33 mBqm−2 s−1 by UNSCEAR stipulated for land surface. The results showed that Ogbomoso region is not prone to high risk of radon exposure to the public. The estimation of the radon flux density value suggested that there is no radiological health hazard such as lung cancer or any other respiratory tract diseases to the inhabitant of Ogbomoso, Nigeria.

Abstract:
Drought can be defined in meteorological terms or in relative terms with respect to hydrology and ecosystems. Meteorological drought is not a necessary or a sufficient condition for fire, because fires burn during conditions of normal seasonal aridity. Drought occurs without wildfires in the absence of ignitions. However, when drought occurs, both live and dead fuels can dry out and become more flammable. Hydrologic drought as natural event is the result of long-lasting rainfall in the catchment area leading to the gradual depletion of water resources in the river network and the occurrence of a drought. Typically, hydrological drought is recorded as a river runoff below acceptable critical value. The authors explore the relationship between hydrological drought and forest fires. They present projections of fire-related drought indicators: the hydrologic indicator 7Q10 (the lowest 7-day average flow that occurs on average once every 10 years). The implementation of the hydrological drought as an approach for fire risk assessment has just started in Bulgaria. For this purpose, the assessment of the feasibility of using the hydrological 7Q10 drought index as a fire hazard indicator in real time is based on archive information on the variation of hydrological characteristics in the river network before and during an actual fire in an accepted pilot catchment. The Hydrologic Index 7Q10 for the pilot catchment of the Struma River was determined according to the rules for the last 15 years (2003-2017) using the daily water flows from all hydrometric stations The results of the presented study confirm the possibility of using the hydrological 7Q10 drought index to assess the risk of real-time fires by information on runoff from operational hydrological stations. One of the largest fires in the Struma River in 2017 occurred in an area identified as a fire on a highly hazard area according to the hydrological drought index 7Q10.

Abstract:
Natural hazards can be initiating events for accidents in oil and gas pipelines. Severe past incidents bear testimony to the risk associated with pipeline accidents triggered by natural hazards (natechs). Post-incident analysis is a valuable tool for better understanding the causes, dynamics and impacts of such accidents. To identify the main triggers of onshore transmission pipeline natechs in the USA, natural gas and hazardous liquid incident reports collected by the Pipeline and Hazardous Materials Safety Administration were analyzed. Potential natech incidents were identified by automated data-mining followed by expert review. The analysis covered ∼21,000 incidents, about 6% of which were identified as natechs. Geological hazards triggered 50% of the identified natechs, followed by meteorological (25%), climatic (11%), and hydrological (11%) hazards. Landslides are the main geological hazard with 43% of the incidents within the category. Among meteorological hazards, lightning is the major hazard with 36%. 84% of the hydrological hazard related natechs were found to be due to floods. Cold-related hazards make up 93% of the natechs caused by adverse climatic conditions. Some preliminary qualitative results on consequences are provided as well.

Abstract:
There is a characteristic phenomenon of mountain landscape in Avalanche. Mountain development entails the need to take into account the avalanche hazard. The important task of the Hydrometeorological Service of Ukraine is to increase the effectiveness of forecasting avalanche danger in mountainous areas of Ukraine. One of the elements on the way to its solution is the digital display of mountain areas in the form of thematic maps. The intensive development of modern GIS technologies and the availability of digital terrain models make it possible to create various thematic maps. The avalanche activity is affected by meteorological and geomorphological factors. Using DEM based on SRTM 1, an avalanche hazard map of Ukrainian Carpathians was compiled. The map is based on the average maximum snow height and the steepness of the slopes. The proposed map will improve the quality of avalanche forecasts and will allow you to determine the need for avalanche exploration if the intended area of construction falls into the avalanche zone and protect users from unnecessary danger. An algorithm for constructing thematic (avalanche) digital maps using satellite data SRTM 1 has been elaborated.

Abstract:
The transportation system for hydrocarbons consists of an important and complex network of pipelines used by oil and gas logistics companies, designed to quickly and efficiently transport oil and gas from its origin, to areas of some demand along territory where operates. Currently Brazil has 15,000 km of transportation pipelines within about 7,500 km of right-of-way pipelines. Along its territorial extension it faces several influences along its route, being the main ones influenced by the external hazards from nature and by third party actions. TRANSPETRO has about 450 water crossings in cataloged water bodies currently. These crossings are currently characterized only according to their geometric characteristics, not considering several aspects inherent to them. The inspections at these crossings are laborious and have a high cost due to necessity of divers and bathymetry in some cases. To monitor the condition of all pipeline water crossings it is important to ensure the pipeline integrity. Depending on hydraulic phenomena, it is possible result in an exposure of the pipelines, free spans, changes in the original pipeline or excessive vibration. These changes can generate high mechanical stresses with both static and dynamic loads. The present study was characterized by the development of a methodology for assessing the susceptibility to the exposure of pipelines as a result of the hydrological hazards present at the crossings in which they are found. Moreover, this evaluation methodology offers a tool to define inspection extent and frequency, as well as the corresponding risk control actions. For this purpose, a pipeline management program has been set up, which consists in the definition of water crossings that constitute a potential hydrological hazard and where they can interact with the pipeline considering the probability of a specific hydrotechnical hazard leading the pipeline the exposure. As a result of this research it was defined a methodology to characterize pipeline crossing areas as well as field survey, evaluation of the susceptibility of pipeline exposure at crossings and the programming of control actions were defined according to the susceptibility found. Finally, the study has also presented a cost analysis of crossings inspections comparing the traditional method to the new premises adopted in this project.

Full text
Abstract:
The Weather and External Forces hazard (WEF) is considered in ASME B31.8 as a non-time-dependent hazard due to its random nature and the high uncertainty of the effects on pipelines given the occurrence of natural events, especially associated with hydro and geotechnical processes. Although there is a wide range of events associated with geological, hydrological and hydraulic conditions (among other things) that can affect a certain infrastructure, only a limited number of these geohazards can cause direct damage to hydrocarbon transportation infrastructure. The identification and understanding of a ground failure process and its association with the susceptibility or physical fragility of the pipeline facing the potential adverse effects of a hazard event, allow to estimate the conditional probability of pipeline failure under loading stresses induced by the event and to estimate the actions needed to mitigate this hazard with methodologies ranging from approaches of structured expert knowledge to methods of structured analysis that incorporate incorporating subsurface investigation, detailed study of the results from terrain monitoring, pipeline and triggering agents through mechanical modeling. This document presents a technical proposal for the management of geohazards which, due to the nature and characteristics of the instability processes and its relation with the activity of triggering agents, and the vulnerability of the pipeline, allow them to be analyzed as time dependent.

Full text
Abstract:
Calculating scour potential in a stream or river is as much a geomorphological art as it is an exact science. The complexity of stream hydraulics and heterogeneity of river-bed materials makes scour predictions in natural channels uncertain. Uncertain scour depths near high-hazard flood-risk zones and flood-risk management structures lead to over-designed projects and difficult flood-risk management decisions. This Regional Sediment Management technical report presents an approach for estimating scour by providing a decision framework that future practitioners can use to compute scour potential within a riverine environment. This methodology was developed through a partnership with the US Army Engineer Research and Development Center, Hydrologic Engineering Center, and St. Paul District in support of the Lower American River Contract 3 project in Sacramento, CA.
