TRANSCRITICAL FLOW SIMULATION USING SHALLOW WATER EQUATION MODEL

Abstrak

This paper shows the capabilities of DELFT3D-FLOW shallow water equation solver on transcritical flow. Two grid
configurations are tested using a shock capturing numerical schemes that available on the solver. The simulation shows a good
agreement with the analytical solution and proper grid resolution is needed to obtain a stable result. Implemented a shock
capturing schemes is found to be critical to obtain a stable result. The model then used to simulate a real scale spillway chute
channel of Logung Dam in Kudus-Central Java. The model could properly simulate the hydraulic jump, calculate the Froude
number and stilling basin performance.
