Site selection flood Spreading for artificial rechargein the north of Andimeshk
Indiscriminate exploitation has been of groundwater aquifers in recent years causinga drop groundwater levels in the plains. Water storage in aquifers by flood spreadingon alluvial fans is a procedure that applicable in many area of Iran. In this Method,with floodwaters to infiltrate into the aquifer in addition to increasing the volume ofthe tank and prevent the severe drop in groundwater levels that are flood control andsoil conservation. Study area is Jarmh watershed this area of 314 square kilo meters innorth of Andimeshk. Alluvial zone is a 4356 ha that distinct by satellite imageprocessing and field works. Effective indices in flood spreading site selectionincluding slope, infiltration, alluvial thickness, transmisivity, flooding and electricalconductivity, selected and measurement in the study area and classified maps for all ofthem was prepared in GIS environment. In next step the maps incorporated by Booleanlogic and weighted overlay index finally the alluvial zone ordered in two classes, highsuitability 2059 ha in Boolean logic and 2485 ha in the weighted overlay index andmoderate suitability 2297 ha in Boolean logic and 1971 ha in the weighted overlayindex.
