Integrated water resource managementfor in Khalifan river basin

This study comprises the application of integrated water resources management (IWRM) in Khalifan River Basin (KRB), north of Erbil province. The overarching goal of this study is to establish 15 years evaluating and analysis plan for Khalifan river basin. The interactions of water users competition have been identified in the basin. In the meantime, some action plans and strategies for the solution have been addressed. The thesis also highlights the top management issues addressing the obstacles to the implementation of integrated water resources management. The water evaluation and planning system (WEAP) model applied to the basin to determine the optimum KRB planning system and the optimum operating policy of the plan. The study compared five scenarios, (reference, high population growth, flow requirement, dam added and water saving). The comparisons show that April to September water demand is high, due to agriculture season. Maximum water demand is 3 million cubic meters, which occurs in August on the other hand the proposed dam only supplied 2 million cubic meters. In addition, for domestic water demand maximum is 0.4733 million cubic meters and the minimum is 0.36978 million cubic meters, and almost has the same level of water demand for each month. Accordingly, the government should start to complete the Gali Ble Dam with a reservoir capacity of 2 million cubic meters. The deficient water demand in the water saving scenario results for both sectors agriculture and domestic start from 1 million cubic meter during the year 2020 and arise to 3.26 million cubic meter in the year 2032.
