The assignment of suitable sites for water harvesting techniques is a promoted strategy to be introduced to the community, for handling the water scarcity and risk due to floods. In the eastern part of Missan, water is always hampered due to the limited availability during the drought, while floods frequently and intensely occur in the wet season. This study aimed to choose the potential and suitable sites for applied water harvesting system using remote sensing techniques and analytic hierarchy process (AHP). Ali Al-Garbi city is divided into three watersheds (site1, site2, and site3), which have been characterized by flash floods that produce high quantities of runoff. The six parameters: slope, lineament density, drainage density, soil texture, rainfall, and runoff. These factors are selected based on previous studies to detect the potential zones of water harvesting system in the study area.Pairwise comparison method consistency index, consistency ratio, and parametersweight is evaluated. The result discovers that the highly probable zone is situated in the north and north-eastern portions in watershed no.1 and watershed no.2, while watershed no.3 located in the south portions. In contrast, the low to medium WH is situated in the center and south portion in watershed no.1 and watershed no.2, whereas in watershed no.3  located in the north.

This research involves the application of spectral indices and GIS techniques coupled with the Analytic Hierarchy Process, to assess  Baglia site, eastern Missan, as a water harvesting potential site. The AHP and pairwise comparison have been used through select four criteria including TWI, TRI, MNDWI, and NDSI, which were deemed as impact factors for this study. All these criteria have been weighted according to their significance in the water harvesting system. The findings of the AHP analysis method explained that the WH potential zones in Baglia site were divided into three zones, namely, high,  medium, and low suitability. The findings demonstrate that  Bglia site, where the highly appropriate zone is located in the deep valley area, is the ideal location for setting up water harvesting operations. The low suitability zone, in contrast, is located in a higher terrain when there is a steep slope area.

Sentinel satellite images are enhanced using Erdas-2014 and analyzed by GIS techniques to distinguish the main geological features in the study area. The enhancement process and correct satellite image with Topography, Geomorphology, and Lithology characterize for landscape classify. GIS method environmental, geological, hydrological, and topographic analysis .to identified and assess the suitable location of Geopark in the eastern masian area. This study shows the east misan area has many suitable sites that can be developed as Geopark. By GIS method can choose the suitable Geopark that achieves the basic requirements set by UNESCO for the establishment of Geopark. It includes The existence of wildlife or watery Presence of geological, geophysical, or hydrological factors Hydrogeology is of importance in the region, and high Geodiversity, the area is of importance to ecotourism, The presence of archaeological sites in the region.
