N2 - Geological structures be of great control groundwater flow and accumulation of groundwater, and should therefore be taken into account in studies related to groundwater studies. This study attempts to investigate the impact of geological structures on groundwater flow and groundwater quality in Al Jaaw Plain, United Arab Emirates. A set of thematic maps derived from digital elevation model (DEM), Landsat images, and ALOSPLAS SAR images were enhanced by applying Sobel filter with 10% threshold and equalization enhancement to map geological structures. Palaeochannels (wadis courses) were derived from DEM using a D8 algorithm. The trends of extracted geological structures and palaeochannels were spatially correlated against the hydraulic head, thickness aquifer, and groundwater salinity in the region. The result showed that the palaeochannels, thickness of the aquifer, and topography are structural controlled by NNW-SSE, NE-SW, and ENE-WSW trending fault zones, significantly influencing the groundwater flow and groundwater pollution in Al Jaaw Plain.
