abstract major of hydrological systems are very complicated and it is not possible to understand them completely, therefore simplification is necessary to understand or control of a part of the system behavior such as water balance relationships. hydrological models are simple structure of complicated systems in water cycle in the nature. the first goal of a hydrological model is function predi...
abstract the aim of this study, is to evaluate the effect of loss methods application on run-off volume and hydrograph shape used by hydrologic models. in this research, four loss methods including constant loss (φ index), initial loss-loss rate, scs and constant fraction approach were applied to be evaluated. to do this, clark rainfall-runoff model was applied for 24 storm events from kasilain...
estimate of sediment load is required in a wide spectrum of water resources engineering problems. the nonlinear nature of suspended sediment load series necessitates the utilization of nonlinear methods to simulate the suspended sediment load. in this study artificial neural networks (anns) are employed to estimate daily suspended sediment load. two different ann algorithms, multi layer percept...
evaluation of sediment yield in watershed scale is considered so important for implementation of soil conservation, watershed management, environment, dam construction and water resource management. using empirical model is one of the approaches of evaluating sediment yield. this research in kasilian watershed evaluates sediment yield by using geomorphology method and epm model with arc view gi...
