 GIS and Analytic Hierarchy Process for Siting Water Harvesting Reservoirs Track: Water Resources Author(s): Wael Jabr, Faraj A. El-Awar In this study, a methodology for siting water harvesting reservoirs was developed and applied in a 300 km2 area of Irsal-Lebanon characterized by low and erratic precipitation to improve the agriculture potential. This involved development and application of a three-step Hydro-Spatial Analytical Hierarchy Process (AHP). First ArcGIS was used to produce pertinent spatial coverages. In the second step, Watershed Modeling System (WMS) was used to simulate the runoff in the watersheds. Finally, in the third step, a decision hierarchical structure using the AHP was developed and implemented to rank various potential reservoir sites according to their suitability expressed in terms of a Reservoir Suitability Index. As a practical outcome of this study, a water harvesting reservoir was actually excavated at the outlet of the highest ranking watershed.
