Assessment of groundwater suitability for drinking and irrigation purposes using physicochemical parameters at Al-Jouf Area, Saudi Arabia

Raid Alrowais1*, Mahmoud M. Abdel daiem2

(2025) 146–152 https://doi.org/10.5004/700086

pdf_ico.png Abstract

Al-Jouf region is one of the most agricultural areas in Saudi Arabia. Due to the increase in drinking and irrigation water requirements in this region, there is an urgent interest in studying groundwater quality. Thus, the main aim of this study is to analyze the physicochemical parameters of groundwater in the Al-Jouf region for irrigation and drinking purposes. Thus, this study investigated some parameters including total dissolved solids (TDS), pH, electric conductivity (EC), hardness, and various anions and cations were compared with national and international standards. The groundwater quality index (WQI) was estimated to evaluate the suitability of groundwater for drinking purposes. The electric conductivity (EC), sodium percentage (Na+ %), magnesium hazard (MH), sodium adsorption ratio (SAR), potential salinity (PS), and Kelley’s ratio (KR) were assessed to evaluate the suitability of groundwater for irrigation. The results of the water quality analysis showed the suitability of groundwater in most parts of the studied area for drinking and irrigation use except that of the Al Qaryat region. Moreover, the groundwater was dominated by alkali metals and controlled by rock–water interaction domain, and the ionic abundance ranking was Na+ Ca2+ > Mg2+ > K+ for cations, and Cl– > SO42− > NO3– for anions. Keywords: Groundwater; Drinking water; Irrigation.

Solar-driven desalination in Saudi Arabia for a sustainable future

Raid Alrowais1*, D. Ybyraiymkul2, M. Kum Ja2, Kim Choon Ng2

(2025) 30–34 https://doi.org/10.5004/700057

Abstract All primary (fossil) energy sources available on planet Earth emanate from the Sun, namely its photosphere (at 5700 K) where useful solar irradiance is acquired either directly or indirectly on a receiver surface. The maximum potential of a solar receiver is gauged by either direct normal (DNI) or global (HGI) irradiance. The literature has...

Fuel allocation in water and power cogeneration desalination plant

Ibrahim S. Al-Mutaz*, Meshari S. Aldalbahi

(2025) 22–29 https://doi.org/10.5004/700028

Abstract Most large thermal desalination plants are combined with power generation, using energy that would otherwise be rejected by the environment. Energy is usually one of the largest operating costs and can vary appreciably with fuel value, plant configuration, and operating mode. In independent or privatized power and desalination plants, the Power...

New developments in mathematical modeling of groundwater systems

Abdelkader Larabi

(2025) 78–80 https://doi.org/10.5004/700104

AbstractThe numerical modeling of groundwater flow in unconfined aquifers is much more involved than in confined aquifers. This is because the governing equation (i.e., Richard’s equation) is highly nonlinear and is subject to nonlinear boundary conditions as well. This nonlinearity is related to the dependence of the relative permeability and the water...
