A WCSPH Particle Shifting Strategy for Simulating Violent Free Surface Flows
TL;DR: An enhanced particle shifting strategy in the framework of weakly compressible δ+-SPH method is developed and a simple criterion based on the estimation of particle concentration is defined to limit the error’s accumulation in time caused by the shifting in order to achieve a long time violent free surface flows simulation.

The layout of submerged horizontal plate breakwater (SHPB) with respect to the tidal-level variation
TL;DR: The submerged horizontal plate is widely regarded as an open-type breakwater and shows a sensitivity to tidal level variation as mentioned in this paper, and nearly all existing studies assume a constant water level.
