Preventing saltwater intrusion in the Coastal of Terengganu, can BRIS soil system help?

Abstract

Coastal zone is among the most heavily populated areas across the world. The increasing population and rapid development in this area could lead to the possibility of over pumping groundwater. If the groundwater extracted excessively, the saltwater could intrude into the groundwater system and cause the problem. Thus, to prevent this situation from happen, the coastal wetland which known as the beach ridges interspersed with swales (BRIS) soil system area need to be taken care of, as it can recharge the groundwater. Even though this area has been neglected and undervalued for their ecosystem services (purifying groundwater), there are the potential of this area to prevent the saltwater intrusion from happened. Hence, this paper will highlight the potential of BRIS soil system in preventing the saltwater intrusion.

“…The composition of salt will lead to corrosion of civil engineering structure. Furthermore, salinity greatly affects the soil surface, contributing to soil erosion and reducing the ability of soil to absorb rainfall, which causes surface runoff and flooding [4]. SI also alters the decomposition of nitrogen, which is essential for plant growth in wetlands and crop plantations.…”
