Laboratory and Numerical Investigation of Saltwater Intrusion in Sandy Beach Aquifer Sloping under Transient Conditio

Abstract

The phenomenon of saltwater advance in coastal aquifers is a global problem. Until now, most of the laboratory studies carried out regarding the advance of sea saltwater have considered the beach boundary as vertical, while the penetration and advance of saltwater from non-vertical beaches to coastal aquifers is a common phenomenon. Laboratory models can simulate the phenomenon of saltwater advancing on sloping beaches. This research expands the past research by building a 3D laboratory model and creating sloping beach conditions. The main purpose of this research is to investigate the phenomenon of saltwater advance on a sloping beach in a laboratory and numerical 3D manner in permanent and non- permanent conditions. An image processing technique was used to analyze the images obtained from the progress of saltwater in the laboratory model. Validation of laboratory results was done with
