“…The drainage density is 0.433 km/km 2 and is typical of coarse drainage. Lithology, infiltration capacity, and topographic relief all influence drainage texture [70]. The low slope of the basement rocks has resulted in a coarse drainage texture (less than 2), which was calculated as 0.059, indicating further groundwater recharge from precipitation.…”

To detect groundwater-bearing potential zones in Wadi Fatimah, western Saudi Arabia, geophysical data from three profiles of two-dimensional electrical resistivity tomography (ERT) and remote sensing data were gathered, integrated, and evaluated. The DEM and slope maps indicate that Wadi Fatimah has a high potential to store great amounts of groundwater. The maximum elevations range from 0 to 933 m, with an average elevation of 466 m AMSL. The amount of surface water that infiltrates into the ground is affected by the slope. Rainwater can be collected in low-sloped areas and percolate into the subsurface, replenishing groundwater. In the study area, the slope ranged from 0° to 38°. The slopes of Wadi Fatimah ranged from 0° to 9.1°, with highlands having slopes ranging from 9.1° to 38°. Wadi Fatimah has a high stream density. Furthermore, because it is unconfined, the groundwater-bearing zone reaches the ground surface and recharges continuously during the rainy season. The drainage density is 0.433 km/km2, which is considered normal for coarse drainage. Lithology, infiltration capacity, and topographic relief all have an impact on drainage texture. Because of the basement rocks’ low slope, a coarse drainage texture of 0.059 was calculated, indicating additional groundwater recharge from precipitation. Moreover, based on the 2D inversion results of the ERT data, Wadi Fatimah’s unconfined aquifer has a high potential for groundwater. This aquifer is distinguished by a zone of low resistivity (less than 100 Ω.m) and a depth of up to 50 m below the ground surface. This aquifer is underlain by the weathered/fractured and/or fresh basement rocks. Wadi Fatimah basin is recharged by rainfall creating a promising or strategic area for groundwater supply for future planning and urbanization projects in surrounding areas.

“…Measurement of morphometric parameters is important, not only to establish the morphological differences of volcanic structures associated with different eruptive styles (Fornaciai et al, 2012;Kervyn et al, 2012;Dóniz-Páez, 2015;Zaidi and Mukhopadhyay, 2015;Bemis and Ferencz, 2017), but also to assign relative ages to these structures (Porter, 1972;Hooper and Sheridan, 1998;Guilbaud et al, 2012;Kereszturi and Németh, 2012b;Kereszturi et al, 2013a;Larrea et al, 2019;Nieto-Torres and Martin Del Pozzo, 2019). Morphometric studies of monogenetic volcanoes have been carried out for different volcanic areas worldwide, usually considering scoria cones (e.g., Hasenaka and Carmichael, 1985) and to a lesser extent, monogenetic volcanoes formed by magma-water interactions (e.g., Martín-Serrano et al, 2009;Graettinger, 2018;Grosse et al, 2020).…”

“…Several geological features make this region distinct: (a) the juvenile age of volcanism continuing into the present (ages <2 Ma), (b) volcanism along the Red Sea coast producing an elliptical-shaped harrat whose east margin is dissected by TGDZ of continental affinity, (c) a regionally extensive tectonic lineament, called the Red Sea Escarpment lies further . Geologic outline for the HAB and As-Sarawat mountains in SW Saudi Arabia (redrawn after Devès et al 2013); the harrat forms a part of the large igneous province in Saudi Arabia (Németh et al 2014;Zaidi and Mukhopadhyay 2015).…”

“…We have presented morphometric analysis on the cinder cones (by definition the cinder cones are steep conical hill formed by the accumulation of glassy volcanic fragments around a volcanic vent) based on satellite imagery to study their eruptive character in the large igneous province in Saudi Arabia (Zaidi and Mukhopadhyay 2015). Results on crustal investigation using the deep seismic refraction method by the United States Geological Survey (USGS) (Healy et al 1982;Mooney et al 1985) and their combined interpretation using geologic and gravity data (Schimdt et al 1983;Gettings et al 1986) led to an overall understanding on the crustal configuration under the Arabian shield and continent to ocean crustal transition under the southern Red Sea continental margin in SW Saudi Arabia.…”

The Harrat al Birk (HAB) of the alkali basalts of the post-Miocene age erupted through a thick Precambrian crust along the Red Sea coast. The 200 cinder cones scatter within HAB and three distinct Bouguer anomaly zones are identified as the coastal gravity high (CGH), axial gravity low (AGL) and a gravity high further east Jabal As-Sawda gravity high (JSGH). Interpreted satellite imagery for 150 sizeable cinder cones in three gravity anomaly zones (134 (90%) in CGH, 10 (6%) in AGL and 6 (4%) in JSGH) are morphologically analysed. The juvenile cinder cones (age <1Ma) are characterised by subvertical slope angles (<40 •) with a variable average geomorphic slope, 27 •-40 • in JSGH, 25 • in AGL and 2 •-15 • in CGH. The oldest cones of JSGH display a high H co /W co ratio with angular asymmetry at their base angles. The major feeder lineaments/faults are oriented NNW-SSE to NW-SE, and they supply volcanic material to cinder cones within a distance of 2 km. The results, when integrated with geological maps and gravity profiles, provide a probable root-plumbing system of the volcano edifice. HAB is the produce of the volcanic process from the source area in JSGH that hosts the major cinders, where the tertiary gabbroic dyke zone acts as a vertical magma sheet for the cinders.
