Influence of Saltwater Submergence on Geohydraulic Properties of Sand: A Laboratory Investigation

Saline water intrusion into freshwater aquifers is a major geohydraulic problem relevant to coastal environment. Apart from contaminating the fresh groundwater resources, saltwater alters geotechnical properties of aquifer materials, affecting resource planning and management. The present study focuses on an in-depth laboratory investigation influence submergence sand. fine sand sample was submerged under saline specified concentrations for specific periods, alteration in their engineering has been studied. It observed that gravity, dry density, permeability significantly affected by period concentration. gravity particles increase almost linearly with While density decreased fairly submergence, same not being increased nonlinearly both concentration; 14 days concentration 30,000 ppm, maximum value.
