NUMERICAL MODELING OF DIKE BREACHING USING SPH METHOD

Soil dikes along coasts are designed to protect harbors and cities from waves such as tsunami. However, overtopping from these structures is an old concern andstill a number of events occur yearly causing both monetary and human losses. In this phenomenon, flood flows and bed changes occur simultaneously. The maindifficulty in simulating the embankment erosion process is related to the modeling of solid transport, because there are intricacies between fluid flow and bed evolution. In the last few decades, many one-dimensional and two-dimensional numerical models have been developed to simulate the embankment breaching (e.g. [1, 2]). In this paper, a multiphase model based on SPH method has been developed to simulate the dike erosion process.
