Rainfall, topography and soil characteristics are considered to control spatial redistribution of phosphorus in catchments. To advance this research, a hydrology model is needed to describe spatial variation of soil moisture dynamics and runoff source areas in multiple runoff events. This study examined whether the spatially distributed, topographically based rainfall-runoff model, TOPMODEL pro...
Fire causes destructive effects on soil, water and components of wetland ecosystems. The aim of this study was to investigate the effects of fire on runoff amount and nutrient concentration of Zrebar Lake watershed between 2014 and 2017 and the return of burned areas to their natural conditions in the short, medium and long term. The results showed that in the fourth year after the fire, the am...
climate change is one of the most important problems in the present century. so assessing and prediction of future changes is important on water resources and so important for economics and socio-economic consequences. the purpose of this research is assessing the effects of climate change on surface runoff volumes under the scenarios: a1b, a2 and b1 using hadcm3 general circulation model and i...
