Abstract
Growing population and increasing water resources demand have caused to slump groundwater level in many plains. Therefore there is a necessary to improve the quantity and quality of the aquifers. One of the most important methods to increase water table in recent decade is groundwater artificial recharge. The main objective of this study is to select sites more suitable for groundwater artificial recharge in Ravansar plain. In view of this, the raster map layers of criteria including geology, slope, alluvial thickness, infiltration rate, permeability, erodibility, land use, percent of silt and clay were prepared. Then each of these criteria was ranked using analytic hierarchy process (AHP) and weighting liner component (WLC) methods for two artificial recharge methods including flood spreading and spreading basin. The results showed that based on the selected indicators and the zonation map in two methods, the best sites located in northern, northeastern and southwestern of the study area and fluvial fans adapted with the best sites for groundwater artificial recharge.
