  • Meshless particle modelling of free surface flow over spillways

    A meshless Lagrangian (particle) method based on the weakly compressible moving particle semi-implicit formulation (WC-MPS) is developed and analysed for simulation of flow over spillways. To improve the accuracy of the model for pressure and velocity calculation, some modifications are proposed and evaluated for the inflow and wall boundary conditions implementation methods. The final model ...

  • Prediction of cavitation damage on spillway using K-nearest neighbor modeling

    Cavitation is a common and destructive process on spillways that threatens the stability of the structure and causes damage. In this study, based on the nearest neighbor model, a method has been presented to predict cavitation damage on spillways. The model was tested using data from the Shahid Abbaspour dam spillway in Iran. The level of spillway cavitation damage was predicted for eight ...

  • Comparison of water supply dams’ spillway performance in Malaysia

    This paper compares the risk of dam overtopping of two rolled compacted concrete (RCC) dams in Malaysia. Uniform methodology was carried out by selecting an appropriate probable maximum precipitation (PMP) series, performing a catchment PMP/PMF (probable maximum flood) rainfall runoff routing and finally, routing the inflow hydrographs through the reservoir water body. The critical PMP/PMF ...
