Abstract
This study aims to determine the optimal locations for rainwater harvesting in the Talandasht region of the province of Kermanshah. As a multivariate analysis, the Analytic Hierarchy Process (AHP) was used to determine the optimal sites. GIS identifies the optimal locations for the Talandasht region based on the biophysical characteristics taken into account. In this study, slopes between five and fifteen percent were given the highest score, while slopes below five and above sixty percent received the lowest score. The soil permeability was measured using soil hydrological groups, with hydrological groups 4 (D) and 1 (A) receiving the highest and lowest scores, respectively. Over 10,000 hectares of Talandasht's total area have a slope greater than five percent, and runoff is flowing in it. If the average annual rainfall is 400 mm, there will be 34285714 cubic meters of precipitation. By determining the optimal storage location, water can be stored and used for additional purposes, including supplemental irrigation and the creation of rainfed gardens. In various regions of the country, rainwater collection has a high executive potential. Conservation and integrated agriculture are excellent opportunities for conserving and storing rainwater in the region and reducing the region's yield gap.
Highlights
- This study determines Kermanshah's Talandasht region's best rainwater harvesting sites.
- Runoff flows in over 10,000 ha of Talandasht's slopes greater than 5%.
- Water can be stored for irrigation and rainfed gardens by finding the best storage location.
- Conservation and integrated agriculture can store rainwater and reduce the region's yield gap.
