| Research Abstract |
In this paper, we focus on the impact on sandy beaches due to tidal cycle variation, especially on the salt concentration of unsaturated ground. We demonstrate experimentally the simultaneous movement of water and salt concentration of unsaturated ground by water retention test using seawater and freshwater and experimental study of leaching by the surface brine variability and rainfall.
