@article{Ikha Magdalena_Leo Hari Wiryanto_2020, title={WAVE GENERATION ON AN INCLINED OPEN CHANNEL WITH A BUMP}, volume={19}, url={https://geomatejournal.com/geomate/article/view/1087}, abstractNote={<p>A uniform flow on an open channel is studied in this paper. Shallow water equations are used <br>as the model by involving the bottom topography. In this problem, we focus on incline bottom and put a bump <br>on it, so that the flow generates a surface wave. The model is extended by energy dissipation through tangential <br>shear and the energy dissipation by shearing normal to the flow. In non-dimensional variables, the profile of <br>the fluid surface is observed as waves growing to split and propagating, depending on the type of the bump, <br>parameters angle of the channel, Froude number and Reynolds number. When the angle is not zero, we found <br>that the waves propagate downward and possible appearing secondary waves or undular bore, that does not <br>occur for zero angles but agrees to the model of Boussinesq equations. To get the accurate result with purely <br>showing the damping effect from the equation, the finite volume method has been applied on a staggered grid <br>that is free from damping error to solve the equations numerically.</p>}, number={76}, journal={GEOMATE Journal}, author={Ikha Magdalena and Leo Hari Wiryanto}, year={2020}, month={Dec.}, pages={126–133} }
