The present study proposes a support vector machine (SVM)-based habitat model linked with evolutionary optimisation to balance the impacts of generating hydropower on downstream river habitats. This method was applied in Rajaei reservoir and Tajan River basin Iran mitigate environmental plants. SVM classified suitability at which sigmoid function considering different slopes applied. Nash–Sutcl...

the performance of the swat2012 model for estimation of hydrological budget in gharasou watershed, west of iran, during 1995 to 2005 was assessed. digital elevation model, hydro-climatological data, soil and land use maps with their properties relevant to the watershed were considered to fulfill the model. a branch program in swat-cup software (sufi2) program implemented to simulate and validat...

introduction: in spite of improving the water productivity due to development in water infrastructure systems, population increasing causing the water withdrawal is triple in the last fifty years. in this situation competition on water consumption especially in the agricultural sector which is the biggest consumer in the world and also in iran is a severe problem. water allocation has been asse...

The limited availability of the recorded rainfall-runoff data for many watersheds restricts development and management different activities water resources. To overcome this limitation, Natural Resources Conservation Service (NRCS) estimating storm excess rainfall momentum optimization methods were combined in a mathematical model to estimate optimal parameters Nash Instantaneous unit hydrograp...

land-use change affects a number natural processes such as soil erosion, sedimentation, flooding and destruction of soil physical and chemical properties. this change of ecosystem causes the degradation of soil quality which eventually leads to a severe decrease in soil fertility. therefore, various aspects of land-use change should be taken into account in national major decision makings. this...
