Indiscriminate exploitation has been of groundwater aquifers in recent years causing
a drop groundwater levels in the plains. Water storage in aquifers by flood spreading
on 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 of
the tank and prevent the severe drop in groundwater levels that are flood control and
soil conservation. Study area is Jarmh watershed this area of 314 square kilo meters in
north of Andimeshk. Alluvial zone is a 4356 ha that distinct by satellite image
processing and field works. Effective indices in flood spreading site selection
including slope, infiltration, alluvial thickness, transmisivity, flooding and electrical
conductivity, selected and measurement in the study area and classified maps for all of
them was prepared in GIS environment. In next step the maps incorporated by Boolean
logic and weighted overlay index finally the alluvial zone ordered in two classes, high
suitability 2059 ha in Boolean logic and 2485 ha in the weighted overlay index and
moderate suitability 2297 ha in Boolean logic and 1971 ha in the weighted overlay
index.
