Résumé
Population growth and ever increasing development of people activities cause to changes in natural ecosystem and water and soil resource. Nowadays reduction of groundwater resources, quality and quantizing of source water, incorrect management of water resources, fade of jungels, water and soil pollution, soil erosion and land use changes are the most important issues in world among iran. Present study is struggle to estimate of effect of land use change on hydrology regime and runoff and then estimate of risk and vulnerability of pollution surface water in basin astane-kuchesfahan swat program for estimate of effect of land use change on basin runoff validation of software in done by swatcup and correlation coefficient and nash coefficient in calibration course period are obtained 0.7 , 0.67 and iin validation course are obtained 0.69 , 0.61 that show acceptable accuracy of software. Land use change in each scenario cause to change in annual average discharge changing of farmland to pasture by reason of increase of contact of rain drops on soil surface and increases of penetrability and evaporation and perspiration is cause to decrease of average discharge and increase of water passing to aquifer and vice versa. Wrastic and nmed methods show that used method due to allocation were weight to contaminant resource with more risk is one of the appropriate method for the estimate of risk of pollution of surface water and its standard method for management and quality protection of surface water in quality course.
