One of the main reason of earth-dam breaks is inner erosion which is caused by washing fine soil particles and finally lead to seepage inside the dam. Seepage will decrease effective tension in the earth-dam's core and arching phenomena is occurred. More settlement of core than to shell is the consequence of arching and occurrence of cracking. In this paper, GeoStudio software based on finite e...

Due to the immense damage caused by dam failure, especially dams constructed near large cities, it is necessary to consider the breaking phenomena as well as studying and designing different parts of the dam. For this purpose, the hydrograph of the outflow due to dam failure must be identified according to size of the fracture and then flood routing, and flood zone must be determined based on t...

The purpose of this study is to model the flow movement in an idealized dam-break configuration. One-dimensional and two-dimensional motion of a shallow flow over a rigid inclined bed is considered. The resulting shallow water equations are solved by finite volumes using the Roe and HLL schemes. At first, the one-dimensional model is considered in the development process. With conservative fini...

A modified moving particle semi-implicit (MPS) method based on GPU acceleration technique is applied to simulate three-dimensional (3-D) free surface flow by using our in-house solver MPSGPU-SJTU in this work. In order to validate MPSGPU-SJTU solver, 3-D dam break and sloshing, two typical violent flows with large deformation and nonlinear fragmentation of free surface are simulated. For dam br...

A one-dimensional model framework of unsteady free-surface flow through a blocking-drag region is developed, tested, and applied to understand the dam-break past rectangular building. This achieved by studying steady-state, adjustment response region. Three steady regimes are identified based on Froude number upstream downstream region: subcritical state, choked state with subcritical-supercrit...

A three-dimensional (3D) non-hydrostatic model is presented for the simulation of dam-break flows. The solves Reynolds-averaged Navier–Stokes equations using projection method. 3D computational grids are constructed from a two-dimensional horizontal unstructured mesh by adding layers in vertical direction. Based on grid system, advection terms discretized momentum conservative scheme. proposed ...
