Hydrodynamic Modelling of Tidally-Influenced Fluvial Zone, a study case of Palembang, Indonesia

The development planning of a tidally-influenced fluvial zone poses complex interaction between river discharge and its effect on the tidal patterns, especially in dense population high economic activity like Palembang located South Sumatra Indonesia. Previous studies numerical modelling this area have focused flood; however, hydrodynamic described is not more detail. present study aims to better understand by using combination qualitative assessment situ measurement data. Hence, water level condition mix discharge. A 2D-hydrodynamic modeling has been successfully conducted assess their properly commercial software, called MIKE21 FM. This describes setting up computational model, boundary location, type forcing (tidal non-tidal), bedform roughness, turbulent viscosity extensive calibration validation. In indicates that site's flow characteristic complex, mixture force from downstream flows upstream which seasons play an important role. It found comparing model outputs data for validation verification process effectively fluvial-estuarine transition Palembang. As shows good reliability, long term line with transport should be developed support rapid development.
