The site selection of Rainwater Harvesting Systems for Sustainable Rural Development in Northern Savadkooh County

Rainwater harvesting systems is an effective method for the utilization of surface water resources in rural and agricultural areas especially and can be considered as a factor for the development of these areas. However, since site selection and identifying suitable places to implement this technology in rural areas is one of the most important and basic steps of using these systems, the main purpose of this study was to determine the location of rain water harvesting systems for sustainable rural development in Northern Savadkooh county. This research was carried out using remote sensing technology and using satellite images, meteorological organization data and geographic information system and Analytical Hierarchy Process. For this purpose, data were collected through pair wise comparison questionnaire by 16 samples among water sources and the paired matrix of criteria and the weight of each was estimated. Then the layers of each criterion were combined and the final layer of susceptible areas was determined. Based on the results, this county was classified into four categories: unsuitable, medium talent, good talent and suitable talent. According to the talent of the region, this city is classified into four categories: unfit, medium talent, good and suitable, and the suitable and good areas cover a total of 57.2 percent of the study area. Applying appropriate methods of rainwater extraction can be used to store rainwater and optimal management to prevent wastage of surface water.
