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...

The sustainable management of water resources, whether surface or underground, requires the identification flows involved and possibility achieving balance resource. These require knowledge main flow components with a sufficient level accuracy. Hydrological simulation models are valuable tools for studying at watershed scale but rely on data that rarely available; therefore, they implementation...

Assessing the status of water resources is essential for long-term planning related to and many other needs a country. According climate reports, change on rise in all parts world; however, this phenomenon will have more consequences arid semi-arid regions. The aim study evaluate effects groundwater, surface water, their exchanges Shazand plain Iran, which has experienced significant decline st...
