“…It depends on the soil's composition, weathering processes, leakage rate, and surface runoff [73,74]. Most of the researchers [49,[73][74][75]85,86] represent the highest drainage density with low rank because they indicate low permeability and low recharge and vice versa.According to the geological investigation, 43% of the exposedrock issedimentary cover and Quaternary deposits (Figure 5). The remaining is distributed among hard rocks with low to moderate to high fractures and joints.…”

“…People who live in the coastal region rely primarily on groundwater resources, and for them, the water The main parameters controlling ARPZ are evaluated based on their impact and influence on water leakage and surface runoff. These factors are soil lithology, land use/cover, lineament density, hydrography expressed as slope, and drainage density [49]. These parameters have the most effective and reliable impact on the aquifer recharge potentiality.…”

There is an urgent need to explore and analyze new aquifer recharge potential zones (ARPZ) in arid regions exposed mainlyto hard rock local aquifers, whether fractured or non-fractured, for investment and fulfillment of the Saudi Vision 2030. Over-pumping, seawater intrusion, climatological changes, population growth, lack of traditional water supplies, expensive desalinized water, and excessive evaporation have characterized the Duba region of Tabuk province of Saudi Arabia (SA). Aquifer productivity and potentiality are affected by surface geology, rainfall, lineament density, drainage density, slope, elevation, soil, and normalized difference vegetation index (NDVI). This study aims to demarcate the ARPZ using integrated remote sensing and geographic information system (GIS) and (RS) approaches. The relative importance of each parameter was determined based on its impact on the aquifer’s potential through the analytical hierarchical process (AHP). The ARPZ zones are categorized into five classes starting from very low to very high potentiality. Southern, western, and northern areas have high to very high aquifer potentiality and recharge. They made up roughly 43% of the area that was examined. About 41.8% of the research area is comprised of low to very low groundwater potentiality, and this potentiality is dispersed over the western and central regions of the region. The medium aquifer potentiality level reflects about 15.2%. The high to very high aquifer potentiality areas coincide with low concentrations of total dissolved solids (TDS), electrical conductivity (EC), and nitrate (NO3). The outcomes emphasized the decisiveness of the entire study and its applicability to any place with similar groundwater aspirations and management.
