“…The Lower Miocene aquifer is represented by the Moghra aquifer that lies to the west of the study area and is composed of gravel and sand with a thickness variation from 50 to 250m (El-Fakharany, 2013). The groundwater flows toward the Qattara depression by a hydraulic gradient doesn't exceeding 0.2 m/km (Eltarabily & Moghazy, 2021) (Fig. 3b) while the recharge is from the Nile River.…”

ROUNDWATER is an important source of water in Egypt that has been heavily exploited in recent decades. This has led to the expansion of the west Nile Delta cultivated area through the New Delta project (in the area to the west of the old Nile Delta), that pose additional stresses on the water resources. Fourteen groundwater samples from the semi-confined and five samples from the unconfined Quaternary aquifers were collected, thirteen samples from the Miocene (Moghra) aquifer, and one sample from the deep Nubian aquifer were also collected and analyzed for various parameters. A comprehensive assessment of the four aquifers in the study area were done using statistical analysis, biplots, Piper and Gibb's diagrams, as well as temporal comparison of the water chemistry. The statistical analysis output indicates the interplay between human activities (anthropogenic factors) and the interaction with the bearing rocks (geogenic factors) that affect the water chemistry of the aquifers. The hydrogeochemistry of the different aquifers indicates that the semi-confined Quaternary and the Moghra aquifers are best used for irrigation, while the unconfined Quaternary aquifer belongs to the Na-Cl water type and the deep Nubian aquifer water is brine according to the salinity classification. Additionally, caution must be taken to mitigate the potential impact of contamination from the use of fertilizers and excessive pumping on the groundwater quality.

“…The main consumer of fresh water is agriculture, which accounts for 60% of crop production and 80% of the cultivated area in the world (FAO, 2021a). This circumstance forced developing countries, including Egypt (Eltarabily, 2022), to recycle drainage water for irrigation reuse, specifically for newly reclaimed land agriculture projects (Eltarabily & Moghazy, 2021;Gabr, 2020Gabr, , 2018aGabr & Elzahar, 2018). The long-term reuse of drainage water leads to deterioration of the water quality, which increases soil salinity (Gabr, 2018b(Gabr, , 2019.…”

Subsurface drainage is effective for not only controlling groundwater levels in agricultural lands but also alleviating soil salinity localized at the root zone, especially for arid and semi‐arid agro‐ecosystems. In this research, an optimization model that minimizes the overall costs of subsurface drainage systems subjected to design constraints was formulated. The Lagrange multiplier method for optimization was utilized to derive a general differential equation for obtaining the most economical design of the subsurface drainage system. Design charts for the minimum cost of the subsurface drainage network ($ ha−1) for lateral diameters (dL) of 2.5, 5, 7.5, 10 and 12.5 cm; hydraulic conductivities (K) of 0.5, 1, 2, 3 and 4 m day−1; different lateral lengths (LL) of 100, 150, 200, 250, and 300 m; a constant collector length (LC) of 1000 m (assuming laterals join the collector from both sides); drainage recharge (q) values of 1, 2, 3, 4 and 5 mm day−1; and excavation depths of 1.5 and 2.0 m were developed. The minimum computed subsurface drainage network (SSDN) costs observed at a lateral length (LL) of 300 m were 205, 246, 288, 331 and 374 ($ ha−1) for lateral diameters of 2.5, 5, 7.5, 10 and 12.5 cm, respectively, corresponding to lateral spacing of 175, 176, 177, 178 and 179 m. The suggested charts for the optimum design of a subsurface drainage system have lower overall costs than using conventional design approaches for pipelines and tube wells. The results will support solutions for designers to implement subsurface drainage systems with less and more affordable expenses in the old lands of the Nile delta of Egypt and other regions with similar agrosystems. Quality control during construction is very necessary for guaranteeing the effective and sustainable performance of subsurface drainage systems for many years.

Groundwater plays a vital role as a natural resource essential for supporting life. This study aimed to evaluate the suitability of groundwater for drinking purposes in the Sidi Alall Tazi region, Morocco, using water quality indices (WQI). Forty-five water samples were collected from different locations in the study area. The investigation focused on the spatial and temporal variations of physical parameters, such as pH, and electrical conductivity (EC), and chemical parameters, such as sodium (Na + ), magnesium (Mg 2+ ), nitrate (NO3 -), chloride (Cl -), potassium (K + ), calcium (Ca 2+ ), and bicarbonate (HCO3 -). The spatial distribution of Ca 2+ , EC, and Na + revealed poor groundwater quality in some wells located near the Nador Canal and the Esbou River. The spatial distribution of nitrates (NO3 -) was higher than the permissible limit in most of the study samples due to the excessive use of agricultural fertilizers in the study area. The results of WQI values ranged from 54.4 to 341. Specifically, samples W33 and W35 were found to be unsuitable for drinking purposes, with WQI values of 341.9 and 317.4, respectively, indicating poor water quality attributed to factors such as river intrusion, overexploitation, and harsh weather conditions. It is worth noting that the majority of the parameter values exceeded the recommended limits set by the World Health Organization (WHO) for safe consumption. By analyzing groundwater quality data and mapping the distribution of pollutants, officials can take measures to mitigate and prevent further pollution.
