Abstract

Abstract. The Mayang watershed at Jember Regency is one of the areas prone to drought in the dry season and flooding during the rainy season. Management of water resources is very important for sustainable agriculture in this area. This article focuses on the implementation of WEAP to study the specific water balance for irrigation water use. The Water Evaluation and Planning (WEAP) model use to calcul water supply and demand for irrigation. The FPR and LPR methode used to calcul irrigation water demand. Irrigation water supply is measured from the measurement site or intake of Irrigation water distibution systems. The result shows that inbalance of supply vs demand exists both for dry and rainy seasons. The lack of water supply during the dry seasons, force the reduction of water supply for irrigation. Therefore, the smart scenario for water management for irrigation need to be implemented during the dry seasons.
