Simulation of wave fronts on dry beds using Lagrangian blocks Available to Purchase

Simulations of wave fronts on a dry bed are conducted using blocks as the computational elements. The non-negativity of the blocks allows simulations of the wave fronts to be carried out without the oscillation problem that limits the applicability of many existing computational methods. At the leading edge of the advancing front, the velocity is maximum and friction dominates. Simulations of this dominant friction effect at the wave front are carried out for the release of water from a dam-break outflow, a levee overflow and a sump outflow. Despite geometric differences, the frontal dynamics of all three flows are similarly affected by friction.
