Abstract

Coastal reservoirs, located near the shores of either seas or oceans, play a crucial role in storing fresh water for residents in coastal regions. Enclosed by concrete walls to prevent seawater intrusion, these reservoirs face challenges due to porous ground layers and direct connections to the sea. This laboratory study delves into the initial stages of optimizing coastal reservoirs, with a specific focus on desalination during the initial water intake process. The investigation highlights that salt removal primarily occurs in the ecotone bed during the initial bed scouring process. After bed leaching in this section and its extension to a specified depth, leaching initiates from beneath the main reservoir area, connecting to the ecotone scouring area. Examination of the shape and pattern of the washed area reveals that the depth of the scouring area surpasses its length along the bed. This study contributes valuable insights into the desalination potential of coastal reservoirs, particularly during the critical phase of water intake, offering a foundation for further research and development in sustainable water supply practices for coastal communities.
