Assessing Suitable Techniques for Rainwater Harvesting Using Analytical Hierarchy Process (AHP) Methods and GIS Techniques

The objective of this study is to produce suitability maps for potential rainwater harvesting techniques (RWHT) in the West Bank (WB), Palestine. These aim reduce water scarcity, which a major problem conservation resources area. Based on literature reviews and expert recommendations, seven RWHts were selected (runoff basin system, contour ridges, cisterns, eyebrow terrace, check dam, on-farm pond, bench terraces). Analysis methods performed Arc GIS environment include spatial analysis data reclassification. Other calculations multi-criteria assigning suitability. Five criteria (rainfall, runoff, land use, slope, soil texture) RWHt analyzed map each technique. results show that runoff systems northeast southwest WB are most suitable, with about 50% area moderately suitable technique, while 70% very ridge Furthermore, shows almost cisterns. Sixty percent puddling, especially north WB. areas high different comprehensively cover WB, as shown integrated map. Nevertheless, approach can help decision makers making an initial selection RWH their region.
