Hydrological information is the basis for conducting water balance studies in any region, and surface runoff one of most important hydrological parameters difficult process estimation prediction. This study aims to verification MIKE 11-NAM Model modeling using artificial neural network (ANN), fuzzy inference system (FIS), autoregressive integrated moving average (ARIMA) methods at Al-Jawadiyah ...

abstract this research investigates the effect of drought on ground water table of neishabour plain. the precipitation data of nishabour synoptic station during 1990-2001, the bar climatology station during 1964-2001 and the data of hydrometric stations of kherv and bar in 1996-2001 have been used as the base of analysis. the method of herbest et all has been used to analyze the drought. using ...

Water resources have always been a major concern, particularly in arid and semiarid parts of the world. Low precipitation its uneven distribution Algeria, along with fast population agriculture activity increase and, particularly, recent droughts, made water availability one country’s most pressing issues. The objectives studies reported this article are to investigate forecast meteorological h...

Abstract. The African continent is probably the one with lowest density of hydrometric stations currently measuring river discharge despite fact that number operating was quite important until 1970s. This new Database Hydrometric Indices (ADHI) provides a wide range indices and hydrological signatures computed from different sources data after quality control. It includes 1466 at least 10 years...

In a watershed, sediment arises due to the erosion and some factors such as pastures destruction,change users, no reasonable cultivation. That causes problems such as sedimentation in reservoirs andreduces their useful volume, reducing water quality in agricultural consumption; reduce the efficiencyof hydraulic structures and some other environmental problems. Changes in sediment load in a rive...
