“…The stable isotopic formation of samples gathered from the Eocene and Nubian aquifers was plotted on the δ D−δ 18 O diagram (Figure 10) along with the global meteoric water line 53 and data from previous studies of the irrigation canals and drains of the Nile River, 54 the Nubian aquifer system of the Western Desert, 24 and the Pleistocene aquifer. 54 The isotopic composition of groundwater from the Nubian aquifer was depleted, indicating that it came from the same source as the samples from the Western Desert.…”

“…The same equation is used to calculate the stable isotope data for hydrogen but with the replacement of oxygen isotopes by hydrogen isotopes in eq 1. The reproducibility of δ values for δ 18 O is <0.1‰ and for deuterium (D) is <1‰. Uranium-series analyses were performed by α spectrometry.…”

“…The examined area was extensively studied to investigate hydrogeology and hydrogeochemistry, as well as to evaluate groundwater quality and its appropriateness for different purposes using numerous approaches. − Furthermore, many authors used isotope analysis to investigate groundwater sources in the Western Desert. − Groundwater is under serious threat of overexploitation in the study area, particularly for irrigation. Industrial and domestic uses have significantly increased groundwater pollution and abstraction, resulting in significant changes in the hydrologic system.…”

“…The study of environmental isotopes is used to solve many hydrological problems involving surface and groundwater resources, as well as to determine the source of groundwater recharge. New water can differ isotopically from water in the catchment area, and environmental isotopes (d 18 O and d 2 H) are useful tools for determining the old and new water contributions to a stream or shallow groundwater.…”

The groundwater of the west Assiut and El-Minia districts was evaluated in this paper using geoelectrical, hydrogeochemical, and stable isotope (oxygen-18 and deuterium) studies. In the studied localities, 42 vertical electrical soundings (VES) were taken to evaluate groundwater potential, and the analysis, as well as collection, of 74 samples of Eocene groundwater was carried out. In accordance with the vertical electrical soundings’ interpretation, there are four geoelectrical formations and two major water-bearing units that act as aquifers (Pleistocene and Eocene). To determine irrigation suitability, the sodium absorption ratio (SAR), electrical conductivity (EC), residual sodium carbonate (RSC), sodium percentage (Na %), magnesium hazard (MH), Kelley’s ratio (KR), and permeability index (PI) were evaluated as irrigation quality parameters. The EC, Na %, and the diagram of the US salinity laboratory indicated that most of the collected samples of groundwater were suitable for irrigation, whereas the RSC and PI pointed out that all of the collected water samples were safe for irrigation. The oxygen and hydrogen isotope values in groundwater samples showed that the Eocene aquifer was recharged by both surface water and the Nubian aquifer.

“…As a result, the recharge to the groundwater aquifers may not be sufficient to support future large-scale agricultural development, which leads to severe problems concerning the continuous decline in groundwater levels, which could be managed using a proper simulation model. Groundwater flow models were developed to address the groundwater conditions in the Nile valley on both sides of the River Nile, Egypt (Abd El- Moneim et al, 2016;Abdelhalim et al, 2019;El-Rawy et al, 2021;Sefelnasr et al, , 2015 This research aims to develop a groundwater flow model for the Quaternary aquifer in the desert area southeast of Sohag governorate to characterize the Quaternary aquifer system and investigate changes in groundwater levels in response to groundwater extraction future for better groundwater management in that area. In addition, groundwater flow direction, groundwater budget, and groundwater-surface water balance has been investigated using this model.…”

The desert area southeast of Sohag is a target area for development and agricultural expansion, where the Quaternary aquifer is the main water resource. In this study, a groundwater flow model was developed for groundwater management and forecasting groundwater levels and flow under different conditions. This model was calibrated under transient conditions for the period 2017-2021. The calibrated model was used to predict the groundwater conditions in this area through three different scenarios. The first scenario assumes that the groundwater extraction rates remain the same for 20 years, while the second scenario suggests that extraction rates were doubled. The third scenario considers the role of surface water in groundwater recharge. It supposes the decrease in the River Nile and the Eastern Nag Hammadi Canal levels by 1 and 0.5 m, respectively. The results of these scenarios indicated that the most drawdown is always in the southeastern part of the study area where the majority of wells were drilled, while the minimum drawdown is in the western side close to the Nile floodplain area where feeding from both surface water and adjacent aquifer unit is predominant. Moreover, the maximum drawdown of 10.5 m was observed in the second scenario in the eastern and southeastern parts. In contrast, the western part is expected to be significantly affected by the third scenario, where the flux from surface water to groundwater decrease. It is necessary to rationalize irrigated water consumption by using the appropriate irrigation method.
