In the eastern part of Missan, water is always hampered due to thelimited availability during the drought, while floods frequently and intensely occurin the wet season. This study aimed to choose the potential and suitable sites forapplied water harvesting system using remote sensing techniques and analytichierarchy process (AHP). Ali Al-Garbi city is divided into three watersheds (site1,site2, and site3), which have been characterized by flash floods that produce highquantities of runoff. The six parameters: slope, lineament density, drainage density,soil texture, rainfall, and runoff. These factors are selected based on previous studiesto detect the potential zones of water harvesting system in the study area.Pairwisecomparison method consistency index, consistency ratio, and parametersweight isevaluated. The result discovers that the highly probable zone is situated in the northand north-eastern portions in watershed no.1 and watershed no.2, while watershedno.3 located in the south portions. In contrast, the low to medium WH is situated inthe center and south portion in watershed no.1 and watershed no.2, whereas inwatershed no.3 located in the north.
