Abstract:
The aim of the study was to improve the productivity of the PADMA 108 F1 tomato grown in the field on gleysol in the off-season by the combined application of a water regime and an organic amendment. The study took place in the off-season (July-August) in 2022 at Yomian-Kouadiokro (7°49N, 5°9W) in the Gbêkê region and Diabo department of central Côte d'Ivoire. The methodology consisted in clearing a hydromorphic fallow (a gleysol) of about 10 years and delimiting microplots in randomized Fisher blocks of 3 replicates. In each replication, 12 microplots of 5m2 were distributed in 3 blocks, each comprising 4 treatments (poultry manure and sawdust composts, NPK12-22-22 fertilizer and the no-fertilizer control). In each microplot, tomato seedlings were transplanted into 10 pots. At transplanting, fertilizers were applied as a basal fertilizer at a rate of 0.5Kg/pack (poultry droppings and sawdust) and 85g/pack of NPK at the foot of the tomato compared with the control. After planting, a regular watering of 60 liters of water was applied to each block using a watering can (10L), subjecting the seedlings to a specific watering regime of 7 waterings/week, 4 waterings/week and 2 waterings/week. The results showed a highly significant specific effect of watering 7 times/week and of the organic amendment (poultry droppings) on the agromorphological parameters with the highest values compared with the other treatments. On the other hand, the best values for tomato agromorphological parameters were obtained with the combined effect of watering 2 times/week with organic amendments (poultry manure compost), NPK 12-22-22 mineral fertilizer and sawdust compost to some extent. In conclusion, this study shows that to improve the productivity of the PADMA 108 F1 tomato in the ecosystem studied in the off-season, a watering regime of 2 waterings per week is appropriate, regardless of the type of treatment applied (organic or mineral fertilizers).

Abstract:
The response of Ulmus minor Miller to Dutch elm disease was observed under combined heavy and light watering regimes. Ramets of two clones, planted in pots, were divided into two groups and each group underwent a different watering regime: heavy initial watering followed by light watering and light initial watering followed by heavy watering. The changeover in watering took place on May 29, 1998, 15 days after plants had been inoculated with a Ophiostoma novo-ulmi Brasier spore suspension. Greater wilting was evident in elms subjected to the heavy initial watering followed by light watering regime than those subjected to light initial watering followed by heavy watering. Non-inoculated plants subjected to heavy initial watering followed by light watering developed large vessel diameters during the heavy watering period and showed approximately 20% wilting during the light watering period. Non-inoculated plants subjected to light initial watering followed by heavy watering developed vessels with smaller diameters during the light watering period, and showed no wilting. The evidence suggests that large vessel formation prior to inoculation associated with water stress after infection increases Dutch elm disease symptoms. The role of water stress in the development of Dutch elm disease symptoms and the implications for elm resistance and breeding are discussed.Key words: field elm, Dutch elm disease, water relations, xylem vessels, breeding, Ophiostoma novo-ulmi.

This study was undertaken to investigate the antibacterial activity of A. vera and C. tora subjected to different watering regimes on S. typhi and S. pneumoniae. Leaves from A. vera and C. tora exposed to different watering regimes of Daily (Control), 2, 4 and 8 days was used to prepare methanolic extracts at a concentration of 100, 50, 25, 12.5 and 6.25 mg/ml using double-fold dilution method, using DMSO and Augmentin (625 mg/ml) as negative and positive controls. The antibacterial sensitivity was determined by measuring the zone of inhibition, followed by Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (MBC). The result showed that, on S. typhi, highest zone of inhibition of 21.5 mm and 18.0 mm on S. pneumoniae were observed at 100 mg/ml when C. tora received daily watering. There was no significant difference on the zone of inhibition of the extract across the watering regimes when the concentration was 100 mg/ml. Extract from A. vera resulted in the highest zone of inhibition of 22.3 and 16.8 mm on S. typhi and S. pneumoniae at 100 mg/ml at Daily watering regime. On both pathogens tested, the MIC of C. tora extract was found to be 50 mg/ml on Daily and 2-Day watering regimes, and increased to 100 mg/ml at 4 and 8-Days on S. typhi; while A. vera exhibited 50 mg/ml MIC across the watering regimes on both S. typhi and S. pneumoniae. The MBC was found to be 50 mg/ml of C. tora extract on both test organisms, while in A. vera was much specific at 4-Day watering regime. Both A. vera and C. tora extra

Abstract:
The global climate models predict changed precipitation patterns with frequent episodes of drought. Scarcity of water is a severe environmental constraint to plant productivity. Plants display a variety of physiological and biochemical responses at cellular and whole-organism levels towards prevailing drought stress. This study included container experiments with three flower crops aster (Callistephus chinensis), helichrysum (Helichrysum bracteatum) and echinacea (Echinaceae purpurea). Drought was simulated by reducing the number of watering’s to field capacity from 25–30 to 85–90 %. Three levels of watering were studied - three times, twice and once a week. The results showed that the cultivation of ornamental plants in containers under reduced watering conditions (twice or once a week) for a period of 3 months led to considerable inhibition of growth and even to plants death. The relative water content and the level of electrolyte leakage vary depending on the weekly number of waterings. The highest values of electrolyte leakage were reported in a single watering for aster -5107.1µS / g, for helichrysum -8314.9 µS / g and for echinacea -3722.8 µS / g. The high rates of conductivity, especially with one-time weekly watering, are evidence of the damage caused by the simulated water stress. This corresponds to the reported low percentages of RWC % and the low values for the height and diameter of the plants. The relative water content in plant tissues decreases depending on the irrigation regime. The lowest values for aster, helichrysum and echinacea were again observed in the variant with a single weekly watering, respectively 15%, 11.5% and 15.8%.

Abstract:
Five citrus proevancnes were subjected to watering levels in the nursery. The effects of watering regime were evaluated on the growth, physiological and biochemical attributes while the measured variables were deployed to rank tolerance to soil moisture deficits by citrus species. The watering regimes were 100 % field capacity (1.2 litres at four days interval), moderately watered: 75% field capacity (0.9 litres at four days interval) and 50% field capacity (0.6 litres at four days interval) which imposed at 16 weeks after transplanting. Data were collected on height and leaf development, root and shoot biomass, chlorophyll content, stomata architecture, proline, membrane lipid peroxidation and antioxidant enzymes (Superoxide dismutase (SOD), Catalase (CAT), Gluthathione (GSH). Citrus provenances differed in growth traits, stomata architecture, proline, membrane lipid peroxidation and and enzymatic activities. Watering regime induced significant changes in leaf chlorophyll and phenolic contents and enzymatic activities of catalase (CAT), superoxide dismutase (SOD), membrane lipid peroxidation (malonaldehyde (MDA) and Guaiacol peroxidase (GPx) in citrus. The 75 and 50% FC watering significantly enhanced MDA and proline and activities of enzymatic antioxidant in citrus seedlings compare with 100% FC watering. Activities of CAT and GPx were enhanced by 75% FC while CAT, SOD and GPx were enhanced by 50 % FC watering. Under water limitations, 75% FC watering can support citrus seedling growth and 50% FC for lemon under soil moisture limitation.

Abstract:
Three cultivars of evergreen azaleas, `Coral Bell', `Hinodegiri', and `Red Ruffle', were grown under four watering regimes in containers and placed outdoors or in the greenhouse. The water content of the growing medium was maintained at either 0.3 to 0.4 or 0.5 to 0.6 m3m-3 from June 16 to August 30, when half of the plants under each of these regime was switched to the other watering regime. Freeze tests were conducted on August 30 and October 9, 1993. Injury to leaves, lower, middle, and upper stems was evaluated visually. Acclimation of leaves and upper stems prior to the August test, in most cases, was not stimulated by reduced water content, while the response of lower and middle stems was cultivar and location specific. The lower water content treatment after August 30 generally increased freeze tolerance of all plant parts regardless of the previous watering regime. The higher water content treatment after August 30 either prevented or delayed acclimation.

Abstract:
The impact of water deficit severity and the specific growth stages at which water stress is applied have been found to have significant implications for both tomato yield and fruit quality. Recent findings have highlighted the influence of water deficits during the reproductive phase on tomato fruit quality. This study aimed to assess the effects of deficit irrigation on tomato fruit quality and overall plant productivity. Cherry tomatoes (Solanum lycopersicum var. cerasiforme) were grown in a greenhouse from August to November 2022. Three distinct watering regimes were implemented: Daily watering (T1), watering every 3 days (T2) and watering every 7 days (T3), starting from the flowering stage and continuing through subsequent plant development stages. The mean soil metric potentials (SMP) were −4.9, −29.7 and −52.8 kPa for T1, T2 and T3, respectively. Various traits of fruit size, fruit biomass, total soluble solids (TSS), water content, glucose content and lycopene content were measured. Additionally, the overall plant biomass and root-to-shoot ratio were evaluated. The results revealed that traits of the fruit size, such as diameter, length, volume and fresh weight, were most favorable when plants were subjected to the T2 watering regime, while higher and lower watering frequencies led to smaller fruit sizes. Interestingly, the TSS concentration had the most pronounced response to drought stress, indicating increased fruit sweetness. However, the fruit water content, glucose content and lycopene content remained unaffected by the different watering regimes. Furthermore, plants subjected to the T3 with the minimum SMP at −196.4 kPa exhibited enhanced development of the root system, prioritizing resource acquisition such as water and mineral nutrients over shoot components. In conclusion, this study provided valuable insights for agricultural practitioners, offering a range of alternatives that can inform optimal irrigation strategies that effectively enhance the quality of cherry tomato yields. HIGHLIGHTS Water deficits during the reproductive phase have a notable impact on tomato fruit quality Three distinct watering regimes, including daily watering (T1), watering every 3 days (T2) and watering every 7 days (T3), were implemented, with mean soil metric potentials for T1, T2 and T3 recorded at −4.9, −29.7 and −52.8 kPa, respectively T2 watering regime resulted in the most favorable fruit size (diameter, length, volume and fresh weight), while higher and lower watering frequencies led to smaller fruit sizes Total soluble solid concentration showed a pronounced response to drought stress, indicating increased fruit sweetness, while glucose content and lycopene content were unaffected by different watering regimes The study provides valuable insights for agricultural practitioners, suggesting alternative irrigation strategies to enhance the quality of cherry tomato yields GRAPHICAL ABSTRACT

Abstract:
Aims: This study was designed to examine the effects of watering regime and biochar on soil properties and performance of seedlings of urban forest tree species (UFTS) in the nursery. Study Design: The experiment was a 5 by 3 by 2 factorial scheme involving urban forest tree species, watering regimes and biochar amendment or not. Place and Duration of Study: seedlings of five UFTS were raised in the Nursery and Screenhouse of Wesley University, Ondo, a rainforest zone of Nigeria. Methodology: Seedlings of five Urban Forest Tree Species (UFTS) were subjected to watering at 80, 60 and 35% field capacity (FC) with or without biochar amendment. UFTS evaluated are: Bauhinia monandra, Delonix regia, Terminalia catappa, Dypsis lutescens and Veitchia merrillii. Results: Watering regime and biochar amendment exerted significant effects on soil physical and chemical properties, physiological attributes and biochemical constituents and performance o the UFTS evaluated. Watering at 60 and 35% FC increased bulk and particle densities but reduced significantly (P&lt;.05) soil moisture content at field capacity compare with watering at 80% FC. Further, the 60 and 35% FC watering exhibited low N, available K+, Ca2+ and Mg2+. Addition of biochar to the variously watered soil considerably reduced bulk density but remarkably increased porosity, field capacity moisture and plant available moisture. Biochar amendment increased soil pH, total and volatile organic matter contents, available K+ and Ca2+, extractable Mg2+ and dissolved phosphate (PO43+). The responses of growth traits and biochemical constituents of UFTS to watering regimes was species specific. Relative to 80 % FC watering, seedling growth attributes reduced significantly under deficit water application (60 and 35% FC) in addition to remarkable accumulation of osmolytes (osmoprotectants) and enzymatic activities. Biochar amendment enhanced accumulation of osmolytes and activities of superoxide dismutase, guaiacol peroxidase and catalase enzymes of UFTS seedlings. Conclusion: Differential watering and biochar amendment affected soil physical and chemical properties and growth of UFTS seedlings evaluated. Biochar amendment of the variously watered soil enhanced seedling growth, and appear as effective strategy for improving soil properties and UFTS performance, and for mitigation of adverse effects of suboptimal watering.

Abstract:
Soils with scarce plant covering are very susceptible to water and wind erosion. Two species recommended for permanent cover of soil are Lotus creticus creticus and Cynodon dactylon. The performance of both species cultivated in pure stands and in mixture and with 2 watering regimes, high (12.64 L/bag) and low (8.36�L/bag), was analysed in polyethylene bags between March and July in greenhouse conditions. With low watering the growth of both species was lower but mortality of plants was not observed. Growth of stems in L.�creticus and stolons in C. dactylon did not stop with low watering. The growth of C. dactylon was higher than that of L. creticus at both watering regimes. Total root and green shoot biomass of each species was affected by watering. Green leaf area, root weight ratio, root hydraulic resistance, and watering efficiency (g biomass/L watering) differed with the combination of species. Green leaf area, root hydraulic resistance, and watering efficiency were higher in C. dactylon than in L. creticus. Root weight ratio was higher in L. creticus than in C. dactylon, but the specific length and area of roots were higher in C. dactylon than in L. creticus. Net photosynthesis rate of each species was only affected by watering regime. Performance of both species was not affected by the mixture and it has the potential to be a successful ground cover.

Digitization note: pgs. 62 & 91 missing from paper copy and not available for rescanning.<br>Effects of three levels of irrigation frequency; five levels of increasing NaCl (max 8000 ppm) in the irrigation water; and, two different soil types on the growth and survival of Italian Cypress Cupressus sempervirens, Oriental Arborvitae Thuja orientalis, and She-Oak Casuarina equisetifolia tree seedings were studied under greenhouse conditions. There were significant differences between the species throughout the stress period with regard to the evaluated parameters. Height, diameter growth, and leaf water potential in all species were reduced by increasing water and salt stress throughout the stress period. Reductions in total, shoot and root dry weight by water and salt stress were significant. Higher reductions were associated with higher water or salinity stress level. However, the species differed in their response to the stress treatments. Thuja had the lowest reductions in all measured growth parameters, followed by Casuarina and Cupressus. Water and salt stress treatments affected foliage tissue ion concentrations in all seedlings. N, P, K, Ca, Mg, Na, and Cl decreased as water stress level increased (except for, Na and Cl in Brazito soil). However, Ca, Mg, Na and Cl ion concentrations increased as the salinity level in the irrigation water increased. N and P decreased with increasing salinity and K was selectively accumulated. The seedlings' health declined with increasing stress treatment level. NaCl treatments caused foliar injury, which increased as the concentration of NaCl in the irrigation water increased. Thuja showed the least injury followed by Casuarina. Mortality was limited to Cupressus seedlings on both soil types. More mortality was noted with the increase in irrigation frequency and salinity level of the irrigation water. Thuja and Casuarina seedlings survived to the highest salinity level (8000 ppm NaCl), but with visible injury. Soil types affected all seedlings morphological parameters, total water potential, and foliage ion concentrations, except for P and Ca. All seedlings (except for Casuarina root dry weight) planted in Pima soil maintained higher growth and better overall health condition than on Brazito soil. Also, total water potential reached lower values in all species planted in Brazito soil rather than on Pima soil. Foliage Na and Cl concentrations on Brazito soil exceeded those on Pima soil. Survival of Cupressus seedlings was less on Brazito soil than on Pima soil. Overall, Cupressus growth was reduced the most on Brazito soil as compared with Pima soil. Growth of Casuarina was the least adversely affected on Brazito soil.

Seedlings were grown in two watering regimes and four salinities ( 0%,1%,2% and 3%). The results showed that water stress and 3% salinity did not cause plant death, but decreased plant growth. Increasing salinity did cause visual symptoms.Well watering increased height growth , dry matter weight , T/R ratio, water potential, and Ca content of plants and Na+ content of soil , but decreased leaves thickness, chloroplast content, Na content ,and Na+/Ca2+ ratio of plants , and Cl- and K+ content of soil. Other attributes of plants and properties of soil were not significantly altered by the two watering regimes. As salinity increasing, Cl , Na , and K content, Na+/K+ ratio, and Na+/Ca2+ ratio of plants , and salinity, Cl- and Na+ content of soil were increased , but height growth , water potential, and Ca and Mg content of plants were decreased. Dry matter weight , leaves water content and leaves thickness of plants that cultivated in lower salinity were enhanced. Cl , Na , and K content, and leaves water content of plants , and salinity and Cl- , Na+ , K+ , and Ca2+ content of soil were decreased with time during cultivation period. Cl and Na may accumulated in various tissues of seedling, Cl content were decreased as follows: drop leaves > leaves > shoot > root. Na content were decreased as follows: leaves > drop leaves > root >shoot. When old leaves aged and drop out, the salt accumulated in those left the tree. The experiment results also showed that plant growth were decreased when cultivated in water stress and 3% salinity . This implied that the well watering and 1% salinity was the optimum for seedlings growth.

Abstract:
Ecosystem Response Modelling in the Murray-Darling Basin provides an overview of the status of science in support of water management in Australia’s largest and most economically important river catchment, and brings together the leading ecologists working in the rivers and wetlands of the Basin. It introduces the issues in ecosystem response modelling and how this area of science can support environmental watering decisions.&#x0D; The declining ecological condition of the internationally significant wetlands of the Murray-Darling Basin has been a prominent issue in Australia for many years. Several high profile government programs have sought to restore the flow conditions required to sustain healthy wetlands, and this book documents the scientific effort that is underpinning this task.&#x0D; In the Southern Murray-Darling Basin, the River Murray, the Murrumbidgee River and their associated wetlands and floodplains have been the focus of the Murray-Darling Basin Authority’s ‘The Living Murray’ program, and the NSW Rivers Environmental Restoration Program. The book documents research aimed at informing environmental water use in a number of iconic wetlands including those along the Murray – the Barmah-Millewa Forest; the Chowilla Floodplain and Lindsay-Wallpolla Islands; the Coorong and Murray mouth; and the Murrumbidgee – the Lowbidgee Floodplain.&#x0D; Within the Northern Murray-Darling Basin, research conducted in support of the Wetland Recovery Plan and the NSW Rivers Environmental Restoration Program has improved our knowledge of the Gwydir Wetlands and the Macquarie Marshes, and the water regimes required to sustain their ecology.

Abstract:
AbstractAs forestland and grazing land grow scarcer and rural poverty persists in developing countries, sustainable natural resource management (NRM) for income generation and poverty reduction is imperative. Although securing property rights on forestlands is fundamental for sustainable resource management, the conditions under which one institution outperforms the others in the efficiency of forest management have not yet reached a consensus. In contrast, forest management under common property regimes (e.g., community forest management) is commonly adopted in developing countries in Asia and Africa. As argued by Ostrom, community forest management is effective in protecting forest resources, but it may fail to provide proper incentives for intensive forest management activities. This paper argues that the community management system performs efficiently for non-timber forests, whereas a mixed management system of private and common ownership is a desirable institution for timber forest management in developing countries. This empirical research conducted a randomized experiment in Ethiopia and confirmed that the mixed management system significantly stimulated intensive forest management activities, such as pruning, guarding, and watering.

Abstract:
This experiment was conducted at El-Obeid ARC Farm, Sudan, covered hot summer, rainy, winter and warm summer seasons for 310 days. Thirty-six non-pregnant Desert goats were used in this experiment. One group was randomly allocated to a shaded condition and the other to unshaded condition. Each group was randomly subdivided into two groups, one group receiving water every day and the other receiving water every other day. Does were mated by using two healthy Desert bucks. For both shaded and unshaded conditions, respiration rate (RR) and rectal temperature (RT) were significantly (P&lt;0.001) higher in unshaded than shaded condition. Watering regime seemed to have no effect. Conception and kidding rates were lowest with the every other day watering regime under both shaded and unshaded conditions, while abortion rates was highest with the every other day watering regime under unshaded condition. Does mortality rate was highest in the shaded condition with the everyday watering regime and under unshaded condition with the every other day watering regime. Kids’ mortality rate was 100% under unshaded condition with the every other day watering regime. Kids’ birth weights were higher under shaded condition with every day watering regime or under unshaded condition with every other day watering regime. Key words: Desert goat, shade, watering regime, respiration rate, rectal temperature, seasons.

Abstract:
‘The watering of the West’ describes the 1902 Reclamation Act (or Newlands Act) that established a National Bureau of Reclamation charged with constructing dams and irrigation projects in the western United States to reclaim the region from arid nature, open new lands for farmers, and restore the American dream for generations to come. The watering of the West required belief in new “scientific” propositions—many dubious—and entailed assigning added responsibilities to experts, often employed by the federal government, who took charge over not only the manipulation of western waters, but also the management of western lands and the regulation of other natural resources. This made westerners ever more dependent on federal stewardship and federal expenditures—and ever more resentful of federal oversight.

Abstract:
This chapter explores the notion of Riga as a “city of God” to which thousands of monk-knights and other warriors arrived to do battle with the pagans in Livonia, which the crusaders called the “Land of Mary.” Here, the chapter considers the city's role in the Baltic crusade as both a regional trading center and as a gathering point for military expeditions against pagans and Rus'. Riga was virtually surrounded by native tribes, and both pagans and newly baptized converts. And within the city was a military order dedicated to holy war. Riga was also, in every respect, a colonial city, dominated by strangers to the region who arrived in shiploads to make a comfortable living, conquer territory, and spread the faith.

Abstract:
Abstract During the hot, sunny summer of 1995, reservoirs in England’s West Yorkshire region ran dry. Despite restrictions on water consumption, demand soared to record levels. Yorkshire Water Services (YWS), the private company in charge of water supplies, obtained emergency permission to increase abstraction from local rivers. Amid concerns over deteriorating water quality and low flow levels, the environmental regulator of the industry carried out ‘fish rescues’ and artificially aerated some rivers (EA 1996&amp;lt;7). Local schools, hospitals, and councils made contingency plans in the event of a failure in water supply. Local officials warned of health epidemics and fire hazards. Unessential uses, such as garden-watering and car-washing, were banned throughout the region. Standpipes (public water taps for access by multiple households) were erected, and YWS warned of ‘rota cuts’ (periodic cut-offs in domestic water supply). The region’s reservoirs were empty, despite having been full only months before, after one of the wettest winters of the century.

Abstract:
Abstract For sludge washing to be conducted in existing Hanford carbon steel tanks, there must be an assurance that the tanks will be safe from failure by pitting, stress-corrosion cracking (SCC) or other failure processes when the corrosion inhibitors present in the waste are diluted during the sludge washing operation. Testing has been conducted previously to define safe operating regimes in concentrated waste environments and moderately dilute waste environments. Due to identification of unsafe operating regimes for moderately dilute waste environments, testing was conducted in more dilute environments to adequately capture the range of possible chemistries during sludge washing operations. Additionally, a small scoping study was performed to identify the corrosion effects of high levels of chloride in the waste environments. Six month exposure coupon tests, slow strain rate tests, and potentiodyuamic scans have been completed on a statistically designed test matrix of twenty-four tests. SCC was not found for the specimens in the static tests or the slow strain rate tests. Pitting and crevice corrosion was found for many of the solutions, but primarily in the vapor phase. Waterline attack at the vapor space/solution interface was common for the range of solutions tested. Gross general attack was found for the specimens exposed to the vapor space of the high chloride solutions.

Abstract:
Abstract Environment and corrosivity monitoring devices generate data that can be used to enhance asset corrosion management practices. Best practices and analysis methods are needed to simplify extraction of actionable conclusions from these datasets. The devices monitor multiple parameters through time to enable environmental severity characterization of locations, mapping of severity within a region, and evaluation of material response. Conclusions can be drawn from this data to inform material selection in design and maintenance actions in sustainment, decreasing corrosion costs over the asset lifecycle. This work begins to clearly define the methods for acquiring, reviewing, analyzing, and reporting corrosivity sensor data for comparison and evaluation of corrosion severity. Devices were deployed at outdoor sites to produce a dataset containing measurements from a spectrum of environmental conditions. Each device monitors relative humidity, temperature, electrolyte conductance, and structural alloy corrosion over time. Site-to-site comparisons of corrosion data show differences in alloy corrosion, consistent with environmental and contaminant data. For a marine site, sensor data was used to quantify the effect of contaminant deposition, as a function of distance from the waterline. With the appropriate processes, sensor-based atmospheric corrosion monitoring enables efficient characterization of environment severity and material performance to inform asset corrosion management.

Abstract:
Soil waterlogging due to excess moisture resulting in hypoxic soil conditions can have detrimental effect on development of many dryland plants growing in locations with temporary water logged soils. Oxygen stress in hypoxic soils can lead to decrease root water uptake and transpiration compared to well aerated soil conditions. In turn reduction of transpiration have a positive effect on soil water budget facilitating the preservation of waterlogged state of the soil. We investigate this phenomenon in a greenhouse pot experiment using sweet corn Zea mays var. saccharate as a model species. After establishment seedlings were subject to a differentiated watering regime ranging for now watering to heavy overwatering resulting in soil waterlogging and flooding. It was observed that the elongation rate of maize seedlings decreased once soil was waterlogged. However soon after soil flooding the elongation reassumed coinciding with appearance of new adventitious roots taping the water layer above flooded soils surface. It is concluded the ability of root system adaptation to change in soil water regime determines the plant species success in sites with periodically waterlogged soils. The feedback between soil aeration status and water uptake can result in swinging between waterlogged and desiccated soil conditions, providing competitive advantages to different sets of species during dry-land and wet-land phases.

Full text
Abstract:
Abstract The Burgan sandstone reservoir in the Minagish field of Kuwait is a complex depositional sequence that makes targeting Upper Burgan sands unpredictable due to channeling limiting the reservoir exposure. The area is complicated further by oil-water contact (OWC) uncertainty due to the long history of oil production. The objective of the well was real-time OWC mapping to provide reservoir insight, maximize pay zone exposure and extend the well life through optimizing the completion and production regime. Recent production pulsed-neutron capture (PNC) logging in an offset well showed watering in the Upper Burgan reservoir. This might indicate a change in the level of the OWC or water coning. Utilization of an ultra-deep azimuthal resistivity (UDAR) mapping service was planned to help locate the OWC below the well trajectory and simultaneously identify and track the desired target sandstone sequence. UDAR has proven its capability to map reservoir boundaries and the OWC in real time, during drilling, earlier than with traditional methods. This facilitates real-time geosteering to drill the well in a single run in the productive zone. The wellbore was placed in the desired zone by using UDAR real-time 1D inversion services. While drilling it had been discovered that the OWC was deeper than expected. The reservoir management team obtained important information to update the oilfield development. UDAR services helped to increase reservoir exposure of the well in the Burgan sand of the Minagish oilfield and enhanced the understanding of the sand deposition structure. It was evident that PNC results in the producing offset well do not represent the OWC level throughout the field; instead, localized measurements may be affected by water coning in that specific area. This information led to a change in the field development strategy. The UDAR real-time 1D inversion enabled optimization of the completion design and perforation intervals, and the understanding of the reservoir potential has been improved. The accurate OWC level evaluation will allow to place more production wells in this location.

Abstract:
Siberian cedar, Siberian cedar pine (Pinus sibirica du Tour.)- a species that, in the conditions of the forest-steppe region of the European part of Russia, is able to increase the productivity of forests and their biodiversity. The purpose of this work is to examine Siberian cedar pine under conditions of introduction in the Lipetsk region. In a comparative analysis of the growth of the species in its natural range with its introduction results, it was concluded that Siberian cedar can be grown on fertile soils of the Central Chernozem region, taking into account the decision on the conditions of its placement on the area. In gardening, you can practice the creation of initially wings and curtains from it when watering, eliminating competition from fast-growing breeds.

Abstract:
Models of four Cape-Island style, and one Maine-type inshore fishing vessels were towed in calm water in the Centre for Marine Vessel Design and Research's (CMVDR's) towing tank at speeds up into the preplanning regime. The vessels have some of the characteristics of high speed displacement/semiplaning hulls, but are more typical of displacement hull design in other respects. Full scale resistance, sinkage, and trim characteristics were established at several LCG's and displacements. The data were compared and non-dimensional resistance curves plotted. An attempt was made to graphically 'collapse' the resistance data to a single line, and in so doing it was found that the resistance depends strongly on displacement and waterline length to beam ratio. Regression analyses were performed on the data at several speed ranges separately for the purpose of producing resistance prediction equations. The results are compared against published material.

Oden, Rikki. Effectiveness of Focused Water Conservation Messaging in the Clackamas River, OR. Portland State University, 2020. http://dx.doi.org/10.15760/mem.67.

Full text
Abstract:
The Clackamas River in Oregon is a drinking water source for upwards of 300,000 people living in the Portland metro region. This river experiences seasonal low flow during the annual dry season throughout summer and early fall when endangered salmon species return to the river to spawn. This dry season also coincides with the highest period of urban water use. Since precipitation is minimal at this time, water users choose to water their lawns to make up for the lack of rain which contributes to water use tripling during the driest part of the year. To promote local water conservation, the Clackamas River Water Providers (CRWP)—who manage source water protection and public outreach and education around watershed issues, drinking water, and water conservation for the eight water providers on the river—have created a water conservation campaign that they intend to promote each dry season for the next several years. First promoted during the dry season of 2019, the messaging focuses on the flow needs of endangered salmon and asks water users to cease outdoor watering altogether. Through focus group discussion and a survey of water users, this research investigates public perception and opinion of the CRWP’s summer water conservation messaging campaign with the goal of improving the effectiveness of the messaging in future dry seasons.
