The document discusses various methods for measuring and simulating wave interaction with coastal structures. It describes a physical wave flume used to model rubble mound breakwaters and armor units. It also discusses numerical simulations of wave run-up, infiltration, and pore pressure using Navier-Stokes equations. A variety of instrumentation is presented, including particle image velocimetry, profilers, and wave run-up gauges to measure wave interaction in both physical and field settings.
