“…Vs profiles can be also used to simulate the groundwater flow in aquifers [56]. In addition, a number of researchers have employed Vs data to assess the potential of seawater intrusion into coastal aquifers [57]. This application originates from the fact that the presence of saline water affects the Vs of groundwater-bearing formations.…”

Shear wave velocity (Vs) has significant applications in geoengineering investigations. With the ongoing rise in carbon capture and storage (CCS) initiatives, the role of Vs in monitoring the CO2 sequestration sites is escalating. Although many studies have been conducted to assess CCS-induced risks, no inclusive research has been conducted integrating those investigations. This study strives to collate and integrate the applications of Vs in geoscience with an emphasis on CCS risk assessment. Based on this research, major CCS-induced risks were detected: induced seismicity, caprock failure, groundwater contamination, fault reactivation, and reservoir deformation. These risks were inclusively described, and the mathematical formulations incorporating the Vs parameter in risk analysis were elaborated. It was concluded that Vs applications can be further extended in monitoring CO2 plume migration, optimizing CO2 injection pressures, preventing shallow water contamination, and predicting CCS-induced seismic events. All these applications require fully coupled hydromechanical analysis based on poroelasticity theory. Hence, various factors including pore pressure, in situ stresses, faults distribution, and poroelastic parameters must be carefully determined before the CO2 injection phase. The mathematical formulations presented in the present study are quite applicable for granting the safety and long-term success of subsurface carbon sequestration.

This study aims to evaluate Rameshwaram's groundwater quality in terms of seawater intrusion. The pH ranged from 6.87 to 7.82, and The EC varied between 0.81 and 13.73, 90% below the allowable limit, TDS observed at 240 mg/L to 4103 mg/L with a significance of 70% in the permitted threshold, The range of the Ca hardness was 60 mg/L to 355 mg/L, with 58% exceeding the limit, the range of the Mg hardness was 50 mg/L to 560 mg/L, with 93% surpassing the permitted limit, and the range of the TH ranged from 180 mg/L to 915 mg/L, with 30% exceeding the limit. F-concentrations range from 1 mg/L to 1.78 mg/L, showing 35% are at harmful fluoride levels, while TS concentrations range from 330 mg/L to 4100 mg/L, with over 65% above the limit. According to statistical explanations by rotating component matrix, component 1 achieved 48.53%, component 2 reached 67.64%, and component 3 reached 90.52%. Under Kaiser normalization, the minimum Varimax value fell within the range of 0.81-330.0. The range of possible Varimax values is 8.73 to 25000.60. The standard deviation varied from 0.3264 to 3867.6154, while the mean deviation ranged from 1.8373 to 1661.0150. An identity of 65% found in one group remaining 35% in another cluster. GIS-based spatiotemporal values of water quality metrics confirm the intervention of sea water intrusion in coastal zone. In conclusion, investigation of water quality in the coastal region exhibits the seawater intrusion problem with supporting results of statistical analysis and GIS mapping.

“…Saudi Arabia has two coastlines, the western Red Sea and the eastern Arabian Gulf, as well as some islands. Scholars have assessed seawater intrusion, GW salinization, and pollution sources in some parts of the western coastal region of the country (Red Sea coast) [ 8 , 23 , 24 , 25 , 26 ]. The eastern coastal region, however, has yet to be covered.…”

Integrated Hydrogeological, Hydrochemical, and Isotopic Assessment of Seawater Intrusion into Coastal Aquifers in Al-Qatif Area, Eastern Saudi Arabia

Seawater intrusion (SWI) is the main threat to fresh groundwater (GW) resources in coastal regions worldwide. Early identification and delineation of such threats can help decision-makers plan for suitable management measures to protect water resources for coastal communities. This study assesses seawater intrusion (SWI) and GW salinization of the shallow and deep coastal aquifers in the Al-Qatif area, in the eastern region of Saudi Arabia. Field hydrogeological and hydrochemical investigations coupled with laboratory-based hydrochemical and isotopic analyses (18O and 2H) were used in this integrated study. Hydrochemical facies diagrams, ionic ratio diagrams, and spatial distribution maps of GW physical and chemical parameters (EC, TDS, Cl−, Br−), and seawater fraction (fsw) were generated to depict the lateral extent of SWI. Hydrochemical facies diagrams were mainly used for GW salinization source identification. The results show that the shallow GW is of brackish and saline types with EC, TDS, Cl−, Br− concentration, and an increasing fsw trend seaward, indicating more influence of SWI on shallow GW wells located close to the shoreline. On the contrary, deep GW shows low fsw and EC, TDS, Cl−, and Br−, indicating less influence of SWI on GW chemistry. Moreover, the shallow GW is enriched in 18O and 2H isotopes compared with the deep GW, which reveals mixing with recent water. In conclusion, the reduction in GW abstraction in the central part of the study area raised the average GW level by three meters. Therefore, to protect the deep GW from SWI and salinity pollution, it is recommended to implement such management practices in the entire region. In addition, continuous monitoring of deep GW is recommended to provide decision-makers with sufficient data to plan for the protection of coastal freshwater resources.
