“…Artificial recharge techniques can be used for establishing hydraulic barriers to mitigate saltwater intrusion while recovering SGD [17][18][19]. These techniques have several advantages compared to traditional methods, including low cost, no inundation storage space, less water evaporation, and improved water quality [20].…”

Controlling the hydraulic heads along a coastal aquifer may help to effectively manage saltwater intrusion, improve the conventional barrier’s countermeasure, and ensure the coastal aquifer’s long-term viability. This study proposed a framework that utilizes a decision-making model (DMM) by incorporating the results of two other models (physical and numerical) to determine proper countermeasure components. The physical model is developed to analyze the behavior of saltwater intrusion in unconfined coastal aquifers by conducting two experiments: one for the base case, and one for the traditional vertical barrier. MODFLOW is used to create a numerical model for the same aquifer, and experimental data are used to calibrate and validate it. Three countermeasure combinations, including vertical barrier, surface, and subsurface recharges, are numerically investigated using three model case categories. Category (a) model cases investigate the hydraulic head’s variation along the aquifer to determine the best recharge location. Under categories (b) and (c), the effects of surface and subsurface recharges are studied separately or in conjunction with a vertical barrier. As a pre-set of the DMM, evaluation and classification ratios are created from the physical and numerical models, respectively. The evaluation ratios are used to characterize the model case results, while the classification ratios are used to classify each model case as best or worst. An analytical hierarchy process (AHP) as a DMM is built using the hydraulic head, salt line, repulsion, wedge area, and recharge as selection criteria to select the overall best model case. According to the results, the optimum recharging location is in the length ratio (LR) from 0.45 to 0.55. Furthermore, the DMM supports case3b (vertical barrier + surface recharge) as the best model case to use, with a support percentage of 48%, implying that this case has a good numerical model classification with a maximum repulsion ratio (Rr) of 29.4%, and an acceptable wedge area ratio (WAR) of 1.25. The proposed framework could be used in various case studies under different conditions to assist decision-makers in evaluating and controlling saltwater intrusion in coastal aquifers.

“…The flow rate of the Sevjur River water has decreased significantly from 26.1 m 3 /s in 1983 to 3.0 m 3 /s in 2013. As a result of lowering the groundwater level on 7.0 thousand hectares of irrigated lands, water consumption for crop cultivation increased by 25% (by 14.0 million m 3 ).The problem emerged in Armenia about the lack of drinking, irrigation and household water in the region requires an immediate solution, including by increasing the water inflow into the groundwater basin.International experience shows that the best way to solve this problem is artificial groundwater recharge[29][30][31][32]. Artificial groundwater recharge (hereinafter referred to as AGR) is not a new concept.…”

The goal of the present research is to figure out how to increase the efficiency with which water resources are used in mountainous relief regions on the example of the Ararat Artesian Basin of the Republic of Armenia. The accumulation of significant water runoffs in reservoirs under difficult hydrogeological conditions requires not only large investments in construction, but also in the transportation of water to the consumer, which is fraught with significant water infiltration losses. The paper shows that by the example of artificial recharge of the Ararat Artesian Basin, instead of building a new reservoir to collect 40 million m3 of water per year, which requires huge capital investments (5.75-6.25 USD/m3), the financial costs can be significantly reduced (0.05-0.075 USD/m3) by pumping the same volume of water into the groundwater basin. The obtained results can be used both in different regions of Armenia and in countries with mountainous relief.
