Spatial Multi-Criteria Evaluation (MCE) was used where sevencriteria layers have been evaluated to identify water-harvesting sites, such asslope, stream order, precipitation, potential evaporation rate, soil type, distanceto roads and the Normalized Difference Vegetation Index (NDVI). This methodhelps in locating water-harvesting sites in suitable places as well as improves themanagement of water resources in the study area. Fuzzy logic modeling was usedto standardize the criteria layers, and the Fuzzy Gamma overlay was used tocombine these layers together in ArcGIS 10.5. Specific criteria were used to unifyall these layers. Finally, the final suitability map for the potential waterharvesting sites in Salah Al-Din area was produced were twelve potential waterharvesting sites within the study area have been identified according to thespecific criteria used for this purpose and have a high potential for waterharvesting. This map will provide optimum sites to build dams in order to storethe water, especially in drought-stricken areas. The results illustrate that the GIScan be used as a decision-making tool in water resources management in ascientific approach, which makes the decision making easier and accurate.
