“…Under steady state environments, the SWI was modeled in coastal region of Saurashtra, Gujarat. Hele-Shaw model of SWI was studied around Surat city, Gujarat [115]. The mode Hele-Shaw was used in this study to assess the progress and shifting of seawater interface both the condition (with and without) of recharge state for three different regions of Surat City.…”

Seawater intrusion (SWI) is a universal concern, intensified and aggravated due to over-exploitation of groundwater, sea-level rise, and climate change in the coastal province. According to the Ghyben-Herzberg principle, the stability between freshwater and saltwater is caused by the density difference between the two, until the pressure equalizes. The keystone of India's geography, economy, biodiversity, and the environment are its extended and vast coastline, which occupies the most precious as well as potential aquifer system. This review mainly fascinated on the status, knowledge, and vulnerability of SWI within the aquifers of the coastal region of Gujarat, India. Foregoing investigations reveal that the meteoric intensification in the salinity of coastal regions of Gujarat is the chief provenance of socioeconomic development and environmental degradation. Different studies are performed to analyze and mitigate the SWI problem. In this region, groundwater over-exploitation is the foremost driver of SWI. There are miscellaneous developmental and management skills and techniques to diminish the SWI in coastal regions of the world. Numerous models are fabricated and established to analyze and epitomize the complications associated with it. Numerical models suggest some valuable techniques to manage groundwater-related problems. This study also delivers some advanced management strategies such as dilution of salinewater by artificial recharge techniques, construction of physical barriers in the subsurface to reduce the intrusion etc. feasible to the coast of Gujarat.
