The proper use of natural resources can preserve these valuable assets. In line with the management of natural resources, land use optimization can be highly useful. The aim of the present study is to propose an appropriate integrative model for optimized allocation of lands for surface runoff and sediment load minimization and net income maximization in Bayg watershed, Iran. In this study, fiv...

Climate change is one of the most important challenges which has effect on river runoff. Warmer climatic conditions have intensified the water cycle, rainfall changes, runoff time and amount. There were several studies with different result on this subject all over the world. Due to the importance of karoun zone and lack of studies, the researcher tried to study the effects of this phenomenon o...

Run off resulted from rainfall is the main way of receiving water in most parts of the World. Therefore, prediction of runoff volume resulted from rainfall is getting more and more important in control, harvesting and management of surface water. In this research a number of machine learning and data mining methods including support vector machines, regression trees (CART algorithm), model tree...

Over the years, many storm water best management practices (BMPs) have been developed to reduce the runoff volume and pollutant concentrations. In general, the concept of BMP takes the four following steps to dispose on-site storm water (USWDCM 2001): (1) to reduce runoff peaks and volumes by minimizing directly connected impervious areas (MDCIA), (2) to provide water quality capture volume (WQ...
