In many crowded coastal urban areas, land is being reclaimed from the sea to expand housing and other construction. The impact of such reclamation on coastal engineering, environment, and marine ecology have been widely studied, but Guo and Jiao (both earth sciences, U. of Hong Kong) look at the impact on groundwater level and seawater interface. They derive steady-state analytical solutions based on Dupuit and Ghyben-Herzberg assumptions to describe the modification of water level and the movement of the interface between fresh groundwater and saltwater in coastal hillside or island situations. Land reclamation increases the water level in the original aquifer, they conclude, and pushes the saltwater interface towards the sea. Thus the water resource is increased in two ways.
