Abstract

Selection of a water harvesting dam site involves a complex array of decision criteria that may have conflicting values. Finding the optimum location requires integration of the capacities of Geographic Information Systems (GIS) and Multi-criteria Decision- Making (MCDM). In this paper, a GIS-based multi-criteria decision analysis approach is used to solve this problem. The approach is based on the extension of Analytical Hierarchy Process using fuzzy quantifiers-guided Ordered Weighted Averaging operators (GIS-based AHP-OWA).  This approach is applied to determine the optimal site of a water harvest dam in Qassim region, Saudi Arabia. Several factors affect the selection of the best location of the target water harvesting dam such as: slope, landuse, soil type, geology, rainfall, drainage network, distance from the road, and distance from the cities, are used. The results showed that using a combination of GIS-based AHP–OWA is proper approach for optimal water harvesting site selection, where this approach provides a generic powerful decision-making tool that allows decision-makers to define a decision strategy on a continuum between pessimistic (risk-averse) and optimistic (risk-taking) strategies. إختيار مواقع سدود حصاد المياه هو عملية اتخاذ قرار معقدة. حيث إن إيجاد الموقع الأفضل يتطلب دمج تقنية المعايير المتعددة مع نظم المعلومات الجغرافية. في هذا البحث تم استخدام  نظم المعلومات الجغرافية بالاعتماد على تقنية AHP-OWA لايجاد أفضل مواقع لبناء السدود في منطقة القصيم في السعودية. تم اعتماد انحدار الحوض، استخدامات الأراضي، نوع التربة، جيولوجية السطح، توزع الأمطار، المسافة إلى الطرق، والمسافة للمناطق المخدمة کمعايير لاتخاذ القرار. أظهرت النتائج أهمية هذه الطريقة في إيجاد أفضل مواقع لبناء سدود حصاد المياه، مع السماح لمتخذ القرار أن يأخذ في الاعتبار سيناريوهات مختلفة بين المتفائلة والمتشائمة.
