Abstract One of the important steps towards optimizing land productivity and water availability for the semi-arid and arid areas is the identification of potential sites for water harvesting. Therefore, this paper uses the Geographical Information System (GIS) techniques to select the optimized sites for water harvesting in Al-Qadisiyah Governorate, Iraq. Geographic water management capabilities are applied as a spatial analysis model. Data from global data repositories are retrieved followed by rescaling them to a spatial resolution to acquire a manageable input data set. The Soil Conservation Service Curve Number (SCS-CN) model is used to calculate the potential runoff as an intermediate input. Multi-Criteria Evaluation techniques are adopted to identify the relative importance and suitability levels of the input parameters set to manage the water supply. The suitability for identifying irrigation pond and dam location(s) was considered in this study. To achieve this goal, the criteria for eligibility for water harvesting areas have been completed on the basis of the conditions in the study methods. Based on the hydrological and geomorphological standards of the study area, suitable sites for harvest areas were identified and it was divided into four classes in terms of their suitability for water harvesting, namely very low, low, moderate, and high suitable for water harvesting. It can be concluded that the findings of this research can be used to assist in water resources management as an efficient planning tool to ensure sustainable development of the water in Iraq who suffers from water shortages.

Introduction Water is a significant and limited resource that has many uses. Global climate variability, growing population, and economic development increase the pressure on resources. Freshwater has become vulnerable to depletion and marginalization especially in semi-arid to arid zones when Responsible Editor: Broder J. Merkel * Marwah M.

rainfall rates are unstable. The Middle East is known as an arid to a semi-arid area where average annual rainfall does not exceed 166 mm/year (Al-Ansari, 1998). Due to this fact, water scarcity became an extremely important factor for the stability of the counties in the area and an integral element in its economic development and prosperity (Al-Ansari and Knutsson,
