“…The constructed storage capacity of the Wadi Bih dam is 7.5 MCM. However, the dam displayed a maximum storage of 6.50 Mm 3 , encountered in July 1998 (Sherif et al 2018), and the dam storage ranges from 0.5 to 2.7 MCM in normal cases. The reservoir of the Wadi Bih dam is filled from time to time due to rain events; therefore, it acts as a mitigation measure and an MAR technique (Fig.…”

“…The catchment is marked by rough topography with steep slopes and very little vegetation. Elevations range from 2087 m above mean sea level at the highest point (amsl) to 65 m (amsl) near the outlet (Ebraheem et al 2012;Sherif et al 2018). The Wadi Bih drainage basin is rectangular in shape, and its drainage basin perimeter (water divide) is 113 km long.…”

“…A small portion of rainwater percolates into the subsurface, and thus, relatively large flood discharges are produced in wadi channels. The mean annual runoff of major wadis in UAE is approximately 120 MCM (Sherif et al 2018;Murad et al 2020). Factors affecting the recharge efficiency include, among others, the geological conditions, hydrogeology, and hydrogeochemistry of the recharge sites, physiography, hydraulic gradients, vegetation cover, types of soil, gravels and loose sediments, fractures and joints, and the secondary porosity of consolidated sediments and rocks.…”

In Ras Al Khaimah, UAE, groundwater from the alluvial aquifer in Wadi Bih was the only source of freshwater for various uses prior to the construction of a seawater desalination plant in 1998. This study was conducted to evaluate the effect of the Wadi Bih dam on groundwater resources and to increase knowledge of the hydrodynamics of the aquifer. A local-scale numerical groundwater flow model was developed and used to investigate the impacts of different groundwater management options on groundwater resources. The calibrated and validated model was defined as the base case, and subsequently, simulations were performed to analyze different management scenarios. The simulations indicated that maximum recharge occurred during years of high rainfall (1995–1998). Minimum recharge occurred in 2000, 2002, and 2004. The major contribution to the water balance was from subsurface inflows from the upper wadi zone and the two tributaries. Overall, the annual water balance was negative in most years, with an average net decline of 0.6 MCM per year, indicating a slow but continuous depletion of groundwater resources. At the end of the simulation, the total groundwater recharge due to rainfall and water storage in the ponding area was 9.81 MCM.

“…The northern Oman Mountains in the Khatt Springs area are composed of Jurassic to Cretaceous Musandam Group limestones. The western Jiri coastal plain consists of Late Tertiary to recent alluvial sediments overlying the Late Cretaceous Juweiza Formation (BGS and MOE 2006;Halcrow and Partners 1969;Sherif et al 2006Sherif et al , 2018. The Juweiza Formation is composed of a sequence of marl and shale with Quaternary aquifer: This aquifer is composed of gravel plains of recent silts and conglomerates and meets the mountain front at a high angle.…”

The Khatt, Madab, and Al Ghmour Springs are important springs in UAE. They are located in the foothills of the Oman Mountains. The water temperature of these springs is relatively high (approximately 39 °C). Overexploitation of fractured aquifers negatively affected the waterflows from these springs. The outflows from these springs are time-dependent and range from 10 to 50 L/s (until 1998) to 1–10 L/s (until 2010). To assess the current conditions of the spring areas, relevant data were carefully reviewed, analyzed, and stored in a GIS database. A 3D-geological model was developed for the Khatt Springs area, which allowed different types of visualizations, calculations, and predictions. In addition, a 2D earth resistivity imaging survey was performed to evaluate the available groundwater resources, characterize the major faults/fractures feeding these springs, and to determine the locations of saturated fractures and karsts and the thicknesses of the unconsolidated materials in the wadis. Borehole and drilling information from observation wells were utilized to enhance the analysis of the earth resistivity imaging data. The described procedures and acquired results indicated that it was possible to determine the locations of two production wells for feeding Al Ghmour Springs with water during drought periods to keep it alive.

“…Many studies were conducted on quantifying the changes in groundwater storage and simulating aquifer dynamics in the UAE. Sherif et al (2018) used the potential recharge method which is based on an empirical method involving multiple parameters, to estimate the recharge component from rainwater percolation to the Quaternary aquifer in the UAE. However, the internal flux, an important recharge component in the eastern region, along the border with Oman, was not considered in their estimation.…”
