The impact of rainbow trout farm effluents on water physico-chemical parameters of Ryjab River was investigated. Five stations were considered at different parts of the river. Station 1 located at the headwaters of the river, station 2 after nearly 30 percent of fish farms, station 3 after 60 percent of fish farms, station 4 after the last fish farm and station 5 located one kilometer after the...

Land-surface models are widely used to simulate and predict the movement of momentum, energy, and matter between the biosphere and the atmosphere at local, regional and global scales. In this study, in order to evaluate the performance of this model in daily simulation of discharge in Gharesou watershed, using a spatial resolution of 0.125 degrees, satellite imagery and global databases to prov...
