“…Van Emelen [25] investigated the ability of numerical models to simulate dike failure by overtopping, comparing the results obtained by making use of different models and sediment transport formulations. An interesting model has been proposed by Mizutani et al [1], who also took into account the effects of saturation and sediment size of embankment materials on the erosion process and, specifically, the effects of infiltration and resisting shear stresses due to the suction of unsaturated grains. Two-dimensional (2D) full shallow-water models for embankment breach have also been recently developed by Guan et al [26] and by Kakinuma and Shimizu [27].…”

“…Their correct design and reinforcement is, therefore, crucial in risk management and damage prevention [1] on the occasion of extreme hydrological events, whose occurrence risk has recently been increased due to climate change [2]. From this perspective, it is very important to understand the mechanisms of internal and overtopping erosion and consequent failure of dikes.…”

Dike erosion is a crucial issue in coastal and fluvial flood risk management. These defense structures appear vulnerable to extreme hydrological events, whose potential occurrence risk seems to be recently increased due to climate change. Their design and reinforcement is, however, a complex task, and although numerical models are very powerful nowadays, real processes cannot be accurately predicted; therefore, physical models constitute a useful tool to investigate different features under controlled conditions. This paper presents some laboratory experimental results of erosion of a sand dike produced by the impact of a dam break wave. Experiments have been conducted in the Water Engineering Laboratory at the University of Cassino and Southern Lazio, Italy, in a rectangular channel: here, the sudden opening of a gate forming the reservoir generates the wave impacting the dike, made in turn of two different, almost uniform sands. The physical evidence proves that the erosion process is strongly unsteady and significantly different from a gradual overtopping and highlights the importance of apparent cohesion for the fine sand dike. The experimental results have also been compared against the ones obtained through the numerical integration of a two-phase model, which shows the reasonable predictive capability of the temporal free surface and dike profile evolution.

“…We verified the accuracy of the ASG method by comparing the results of an experiment for infiltration of water into an embankment conducted by Mizutani et al (2013) with the results of a numerical simulation of this experiment with the In the experiment, water level in the channel on the upstream side of the embankment was raised to 0.30 m, which was equal to the total height of the embankment, so that water infiltrated into the embankment.…”

“…Then we derived the dimensionless formulas of ASG method in this study. The next aim was to compare the movement of water and water saturation in an embankment composed of a porous medium as simulated by the AGS method with the results of a water tank experiment conducted by Mizutani et al (2013). Finally, we applied the ASG method to a practice problem to evaluate its ability to simulate the movements of gas and water when water flows over an embankment.…”

We developed a numerical method (ASG method) for simulating a coupled atmospheric gas-surface water system, simulated by Navier-Stokes equations, and groundwater system, simulated by water saturation equations. Here, we derived dimensionless formulas for ASG method to avoid the influence of a dimension of analytical domain, in this study. Further we used the ASG method to simulate the configuration and movement of the infiltration front in an embankment composed of sand and obtained results similar to those obtained by a water tank experiment in another study. In addition, in a practice problem using non-dimensional values, we simulated the movement of gas and water when surface water flowed over an embankment expressed in dimensionless form.Consequently the ASG method could simulate the movement of water and gas across the interface between a surface system and a porous medium including the practice embankment.

Embankments are usually constructed along rivers as a defense structure against flooding. Overtopping failure can cause devastating and fatal consequences to life and property of surrounding areas. This motivates researchers to study the formation, propagation, and destructive consequences of such hazards in risk analysis of hydraulic engineering. This paper reports a numerical simulation of failure processes in homogeneous embankments due to flow overtopping. The employed numerical approach is based on a double-point two-phase material point method (MPM) considering water-soil interaction and seepage effects. The simulated results are compared to available laboratory experiments in the literature. It was shown that the proposed method can predict the overtopping failure process of embankments with good accuracy. Furthermore, the effects of the cohesion, internal fiction angle, initial porosity, and maximum porosity of soil on the embankment failure are investigated.2 of 15 breach, since the real overtopping failure phenomenon is, in fact, an unsteady process involving large deformations, free-surface flows, moving boundary, and water-soil interactions. To deal with these challenges, several meshless methods, such as smoothed particle hydrodynamics (SPH) [13,14], moving particle semi-implicit method (MPS) [15], element-free Galerkin method (EFGM) [16], and material point method (MPM) [17,18], have been developed to model large deformation problems. For examples, Gotoh et al. [19,20] modeled embankment erosion due to overflow using MPS, Li et al. [21] simulated erosion of HPTRM levee based on SPH, Zhang et al. [22] modeled failures of dike due to water level-up and rainfall using SPH, Liu et al. [23] simulated piping erosion process of dike foundation by EFGM. Nikolic et al. [24] presented a discrete beam lattice model capable of simulating localized failure in a heterogeneous fluid-saturated poro-plastic solid. Zhao and Liang [25] applied MPM to model seepage flow through embankments, Martinelli et al.[26] modeled the failure of a sand dike due to seepage flow using two-phase MPM. In this work, the MPM was employed for modeling the overtopping failure of embankments because it has several advantages over other meshless methods such as EFGM, MPS, and SPH: The boundary condition realization is as easy as in the finite element method (FEM) for the use of background mesh in MPM [27]. Time-consuming neighbor particle searching is required in SPH, MPS and EFGM, but the MPM requires only the identification of particles relative to the background mesh. The MPM also avoids the tensile instability that is evident in the SPH [27].The MPM was first proposed by Sulsky et al. [17] in 1994, which uses the Lagrangian particle and the Euler background mesh to describe large deformation problems. The particles move freely across the background mesh and carry all physical parameters such as stress, density, mass, velocity, and other historical variables. The MPM combines the advantages of the Euler method and the Lagrangian method ...
