Dispersive Model for Undular Hydraulic Jump behind a Weir

Abstract

In this paper, we investigate a suitable weir design which yields in an undular jump phenomenon using both hydrostatic and non-hydrostatic models. We solved the hydrostatic model using numerical and analytical methods. After that, we validated the output from both methods using the experimental data. In order to simulate the undular jump better, modification towards the hydrostatic model is needed. Hence, for the non-hydrostatic model, we consider the existence of hydrodynamic pressure and solved the model numerically. The outcome of this paper can be beneficial for hydraulic structures design and the management of water resources.
