Abstract

Groundwater is a significant freshwater source due to rising water demand for agriculture, industry, rapid population growth, and home usage; however, coastal groundwater is at risk of pollution from seawater intrusion due to intensive pumping.

Heavy extraction of groundwater to meet rising demands has resulted in lower groundwater tables and less seaward freshwater flow. As a result, saltwater spreads further inland, threatening fresh groundwater supplies. Saltwater intrusion refers to the introduction of saltwater into an aquifer system. Around the world, there are several coastal and deltaic regions in which seawater intrusion occurs. Underground water supplies are made worthless when seawater flows inland to production wells. The most frequent cause of contamination in coastal aquifers is seawater intrusion. In order to safeguard the resources of groundwater in coastal aquifers, a variety of techniques have been employed to mitigate saltwater intrusion. A brief amount of research has focused on preventing seawater intrusion to safeguard coastal areas' groundwater supplies. To manage coastal aquifers and mitigate seawater intrusion, withdrawal procedures must be carefully planned. Thus, it is vital to effectively manage seawater intrusion to prevent the depletion of groundwater supplies.

New techniques for controlling seawater intrusion are given and discussed in detail. The SEAWAT code was used here to investigate the effectiveness of different controlling techniques to mitigate seawater intrusion. The outcomes of this research can be implemented to achieve sustainable development of groundwater resources in coastal aquifers.
