Drought Utilization Management of Surface and Ground Water (Case study: Qaryat-Al-Arab Watershed)

Abstract

Inattention to water as a key parameter of sustainable development, leads the long-term and planned management for the water to be marginalized. In this regard, proper and optimal utilization planning and management of surface and ground water resources is very important. In this study drought utilization motitoring and management of surface and ground water resources for the Qaryat-Al-Arab watershed, located in Kerman, has been investigated. Kerman is among the regions of Iran that does not benefit enough precipitation. At first the region drought status was predicted and monitored using K nearest neighbor (KNN) model. The present model gave appropriate estimations of drought status for the study area, and reasonable values of the statistical coefficients showed that the present model is efficient and suitable. Finally due to the drought status and classification and also surface and ground water resources condition, the water resources allocation respect to the management modeling were proposed for the study area.
