Abstract: Precipitation droughts were defined using monthly precipitation time series and different truncation levels—namely, 70%, 80%, 90%, and 95%—in which a 70% truncation level means that 70% of the recorded monthly precipitations ...

Abstract: For the purpose of irrigation and water resources planning, it is important to know the water loss for a drainage basin. Unfortunately individual measurements of elements of the total water loss are not realistic, at least ...

Abstract: Droughts are defined using daily streamflow series and different truncation levels including 30%, 50%, 60%, 70%, 80%, and 90% of recorded daily flows. Flow ratios, which are obtained by dividing subbasin flows of different ...

Abstract: The flood frequency analysis has been widely conducted where gauging stations are available and statistical distributions can be used to analyze historical data. On the other hand, flash floods usually occur at unexpected ...

Abstract: The loss of topsoil in the United States has resulted in low crop yield, reduction of reservoir capacity, cost increase of water treatment, and detrimental effects on aquatic life and wildlife habitats. An initial step for ...

Abstract: Soil erosion, more than any other factor, has more significant and direct impacts on a hydrological watershed in terms of environmental problems. After deriving the erosion hotspots, this study used them to investigate two ...

Abstract: During periods of drought, an important goal of water-resource management is the establishment of realistic reservoir operating policies for water allocation, especially for a river system involved with flood-control ...
