using integrated remote sensing and GIS in southern parts of Iran

Water shortage in arid and semi arid regions is serious. Use of flood-water is asolution to provide water to agricultural and grazing lands and to recharge the groundwater.Groundwater development programs need a large volume of data from various sources. This study used integrated remote sensing and geographic information system (GIS) techniques to provide an appropriate platform for convergent analysis of multidisciplinary data and decision making for artificial recharge to groundwater. Thematic maps were constructed using remote sensing and field investigations. Remote sensing and the geographical information system (GIS) are used to integrate four contributing factors: land use, soil texture, streamflow, and slope by the means of Boolean logic. By using this method, the suitable sites for replenishing groundwater in the study area were identified. The resultant map of the groundwater potential zone, demonstrates that the highest recharge potential area is located towards the upstream regions in the plain because of the high infiltration rates caused by sandy clay and range land use. In contrast, the least effective recharge potential area is in downstream regions due to the low infiltration of fine sediment and high slope.
