Abstract
A series of laboratory experiments has been performed to investigate the behaviour of interfacial layer of saltwater wedge in estuary. Experimental conditions have been established according to densimetric Froude number, which is a dimensionless number comparing inertia force with buoyancy due to the density difference. To observe the behaviour of saltwater wedge, conductivity meter has been used to detect salinity. Time averaged and temporal variation of observed properties have been analyzed to determine and investigate the interfacial layer. The location and profile of interfacial layers have shown the dependency on densimetric Froude number. The thickness of interfacial layer has been also dependent on the variation of densimetric Froude number.
