abstract prediction of input flow into water resources is regarded as one of the most important issues in optimum planning and management in producing electro-water energy and optimum allocation of water into different consumption sources. different parameters affect on input discharge into dams. climate variables including temperature and rainfall have the most effect on input runoff rate to w...

Water resources in arid and semi-arid regions are heavily influenced by climate change, water shortage, water regulations, and increased water demands. Monthly discharge is one of the most important factors in hydrological studies. Some of the basins are not equipped with adequate hydrometric equipment. In such a case, average monthly discharge could be estimated by regional monthly water balan...

the necessity of using discharge data in hydrological designs and regional programming is an unavoidable matter. unfortunately, malfunctioning of observation instruments, natural disasters and other problems sometimes result in incomplete or missing data. having of data related to time series is necessary for every investigation about hydrometeorology. thus missing data should be estimated in a...

there are different methods of reconstructing hydrologic data. depending on the conditions of the station a particular method can produce the best results. generally, in order to estimate the lost data in a station and its surrounding stations, hydrologic, climatologic and/or physiolographic similarities are used. recently, the fuzzy regression method has been used to reconstract the hydrologic...

monthly discharge is one of the most important factors considered in designs and hydrological works. some watersheds are not equipped with needed hydrometric equipment. in such a case average monthly discharge could be estimated from regional monthly water balance models of representative watersheds. in this study, thornthwaite & mather (tm) model were used in the pishkouh watershed in arid...
