Characterization of paleodrainages in desert regions of Saudi Arabia multisatellite images with field based study by Mashael M. Al Saud

“…Hydro-geomorphological-based categorization of these paleodrainages was carried out, indicating the majority of SW-NE trending and the presence of routes, unconsolidated sediments and rocks. From the hydrological point of view, these paleodrainages are potential for groundwater storage; and they can be also suitable sites for artificial groundwater recharge; be-sides they represent routs for saltwater intrusion on-land; and these science-based clues represent supportive element for better water resources management in Saudi Arabia.…”
