Abstract
A set of macroscopic model equations for describing the interaction of dam-break waves and porous media is presented. A mathematical model based on spatial averaging theory proposed by Slattery [1] is derived. The large eddy simulation turbulence model and the moving-solid algorithm are incorporated for observing the wave behavior within porous media. The model is validated using two-dimensional experimental data for dam-break wave interaction with porous structures [2], three-dimensional dam-break wave evolution [3,4] as well as impact force of dam-break wave on an impermeable vertical column [5]. Numerical experiments of three-dimensional dam-break waves impacting porous media are subsequently performed. The net force on the structure and the horizontal velocity on a fixed point are also discussed.
