Mississippi State University researchers working at the Center for Advanced Vehicular Systems (CAVS) are performing supercomputer simulations in an attempt to determine how much water levee systems can withstand before breaking and leading to flooding.

The researchers created computational models by developing algorithms that represent millions of particles of soil and fluid to create realistic simulations involving a variety of different soil types and fluids.

The CAVS researchers are using Mississippi State's High Performance Computing Collaboratory's large computer cluster to solve the complex problem at a faster rate.

"Using modeling and visualization, we can obtain a reasonable estimate of what will happen and eliminate the risk," says CAVS researcher Bohumir Jelinek. He is working with experts from Mississippi State's civil engineering department to explore applications such as the strength of saturated soil, sedimentation, and shear thickening by combining the three-dimensional Lattice Boltzmann Method (LBM), which models fluid, and the Discrete Element Method (DEM), which models solid particles.

In addition, the researchers are adding flexibility into the DEM/LBM system, which will assist in solving more problems from various applications, such as fluid injection, piping erosion, and the reliability of the flood-protection systems.
