Groundwater plays a crucial role in supporting human activities and ecosystems. This study conducted a thorough evaluation of the significant of groundwater potential in the study area using Geographic Information System (GIS) techniques. Various thematic maps, such as those depicting lineament density, drainage density, slope, soil, precipitation, and land use land cover, were created and integrated into the analysis. The Analytic Hierarchy Process (AHP) method was utilized to assign weights to each thematic map, achieving a consistency index of 0.61.

The presence of sediment deposition and erosion in the Nun River significantly impacts water quality. While sediment deposition fosters habitats for aquatic life, excessive sediment can lead to pollution and turbid water, hampering photosynthesis and endangering organisms. Conversely, insufficient sediment diminishes habitat availability for bottom-dwelling organisms. This study aims to model sediment yield and river bank erosion in the Nun River Basin.
