Abstract

As a result of huge-scale irrigation project in the Soviet age, serious water scarcity has occurred in the Aral Sea Basin. Sustainable irrigation project is required and this has to be based on feasible water resource and water demand in irrigated farm. In this study, irrigation scheme in SiBUC was modified to consider irrigation types in the basin. These are drip irrigation and furrow irrigation and irrigation efficiency was quite different between them. As a result, the difference was clearly considered especially in soil moisture and evapotranspiration, and flexibility of land surface model was cleared. In addition, historical change of water and heat balance was analyzed by land surface model SiBUC, and it was integrated with the Aral Sea shrinking model and impacts of irrigation projects on the Aral Sea area and volume was physically reproduced.
