Stratification model of seawater mass structure at the estuaries of Jeneberang River and Tallo River and the influences to current pattern in Makassar coastal areas

Abstract

The influences of periodically continuous tides and river discharges flowing from upstream will be responded by basic morphological form and geometry of estuaries and resulting in current pattern in estuaries. The current induced by tidal effect creates turbulences in estuaries which influence the change of configuration of stratification of seawater mass structure and suspended sediment. The intrusion of seawater from estuaries upstream in Jeneberang River and Tallo River will affect the pattern of water mass mixing which later generate patterns of current and sediments on the river. Mathematical model is a useful method to predict structural stratification of seawater mass flowing from estuaries upstream. The stages were to develop mathematical model of tidal current and mathematical model of water flow downstream.
