Studies.of Hydrological Regims of Feral River & itʹs Role in Feeding Mashhad Plain Aquifer

In this paper, we use statistical methods and existing softwares to show the relationship between climatological and hydrological components of the watershed basin of ferezi river. This research shows that in the aforesaid basin, distribution of the precipitation in winter and spring is influenced by the altitude and geographical situation. Also, hydrological regim of the river is alternative and is affected b the kind and seasonal changes of rainfall and snowing which is over flowing with the beginning of snow fusion and spring showers. Analysis of pizometric map of alluvial fan area, shows that annually, increasing valume of flood water, infiltrate in lower part of river aquifer and feed it. With regard to continuous drawdown of underground water surface of the region and deficiency of water supply, it is possible to feed it artificially and strengthen potential of underground water with river flood.
