@article{Dhemi Harlan_Mohammad Bagus Adityawan_Dantje Kardana Natakusumah_Nur Lely Hardianti Zendrato_2019, title={APPLICATION OF NUMERICAL FILTER TO A TAYLOR GALERKIN FINITE ELEMENT MODEL FOR MOVABLE BED DAM BREAK FLOWS}, volume={16}, url={https://geomatejournal.com/geomate/article/view/2871}, abstractNote={<p>The dam break-induced propagation over a movable bed has given strong interest in numerical <br>modeling. The shock wave, generally found in the wavefront, is a challenge in numerical modeling since this <br>condition often leads to numerical instability. Additionally, the scouring beneath the wave requires coupling <br>of hydraulic and sediment transport models. The objective of this research is to develop a one-dimensional <br>model based on a finite element method to simulate an experimental case of a dam break-induced flow and the <br>bed scouring beneath it. The two-step Taylor Galerkin scheme is used to solve the governing equations. In <br>addition, Hansen numerical filter is used to handle shock wave and to increase the numerical stability of the <br>developed model. The results show good agreement to the experimental data. Additionally, the applied <br>numerical filter is able to reduce oscillation and improve the stability of the model.</p>}, number={57}, journal={GEOMATE Journal}, author={Dhemi Harlan and Mohammad Bagus Adityawan and Dantje Kardana Natakusumah and Nur Lely Hardianti Zendrato}, year={2019}, month={Jan.}, pages={209–216} }
