The present study presents the analysis of a moderate earthquake (Mw 4.0) and its largest aftershocks located along the Red Sea coast, southwestern Saudi Arabia, with the aim to understand the enigma of peculiar seismicity in the Arabian Shield. We analyzed a high-quality waveform dataset collected from ten well-recorded earthquakes of moment magnitude ranging from 2.0 to 4.0 in order to determine the hypocenter locations and focal mechanisms. The focal mechanisms were retrieved from the regiona...

Wadi Nisah which lies to the south of Riyadh city is an important source of groundwater supply and agricultural production in the central region of Saudi Arabia. Twenty-nine groundwater samples were collected from wells tapping the shallow alluvial aquifer as well as the Mesozoic Manjur and Dhruma aquifer in western Wadi Nisah. The interpretation of the results of the major ion analysis reveals that geogenic factors mainly rock–water interaction and mineral dissolution control the groundwater ch...

Regional groundwater modeling is a valuable tool for ensuring the sustainable development and management of groundwater resources as it allows the assessment of the aquifer behavior under different types of hydrological stresses. The objective of this study was to use 3D flow modeling to assess the best options for managing groundwater in the Wadi Baysh basin in Saudi Arabia. The model for the Wadi Baysh aquifer system was based on groundwater monitoring data for 10-year period from 2007 to 2016...

Hydrochemical processes have a great influence on the groundwater quality especially in arid regions where groundwater is the single most important source of water supply. The present study was carried out in the Wadi Ad Dawasir region of Saudi Arabia. The objective of this study was to determine the processes influencing the groundwater composition in the region by integrated hydrochemical and statistical assessment. Hydrochemical data from 140 groundwater samples were interpreted using hydroch...

The objective of the present study was to assess the deterioration in groundwater quality due to saline water intrusion in the Ad-Darb region of southwestern Saudi Arabia. An integrated approach using geochemical and geophysical methods was applied to assess the extent of saline water intrusion. Geochemical methods involved the determination of main groundwater facies present in the region using Piper and extended Durov plots. The geophysical methods used in the study included seismic refraction...

Groundwater samples were collected in May 2015 from 23 wells distributed in the western part of Wadi Nisah, mainly used for irrigation. Calculation of saturation indices showed that the samples were generally undersaturated with respect to halite, gypsum, anhydrite, calcite, and aragonite. Groundwater facies analysis showed that most of the collected samples were dominated by Ca–Na–SO4-type water. This water type indicates rock–water interaction, mainly gypsum dissolution. The second major water...

Twenty infiltration tests and 12 pumping tests were carried out in Wadi Baysh in southwestern Saudi Arabia. The objective of the study was to assess the soil and aquifer permeability from the point of view of artificial groundwater recharge. Infiltration tests showed that the soil permeability values ranged from 0.58 to 37.15 m/day and showed good recharge potential. The analysis of the pumping tests showed that the aquifer permeability values ranged from 2.6 to 57.4 m/day and were approximately...

The central region of Saudi Arabia is underlain by thick sedimentary formations belonging to the Mesozoic and Cenozoic era. These sedimentary formations form a prolific aquifer supplying groundwater for agricultural and domestic usage in and around Riyadh. The region south of Riyadh City is well known for agricultural activities. Wadi Sahba, which is an eastward extension of Wadi Nisah, has readily available groundwater resources in the Cretaceous Biyadh sandstone aquifer to sustain agricultural...
