Benchmark Problem #1
The experiments chosen for this benchmark were conducted at the O. H. Hinsdale Wave Research Laboratory at Oregon State University. The goal was to measure debris movement of a small number of large particles over an unobstructed and obstructed beach. The debris consisted of rectangular plywood boxes and were placed unconstrained on a flat section of the beach. A single wave crest was generated, and the debris was allowed to move with and without obstacles.
Complete details of the experiment can be found in the accompanying journal paper:

This benchmark is ideal for testing models with debris-fluid coupling, FSI, and/or 3D hydrodynamics. While all are encouraged to attempt this problem, due to the finite and vertical-walled properties of the debris and the obstacle, those with shallow-water based models may find two-way coupling challenging.
Modelers are asked to simulate four different configurations in this paper; two with obstacles and two without. Modelers may use their own hydrodynamic models, or they may use the Boussinesq-predicted wave results given below (for one-way coupled debris models). Modelers may also find the data comparison scripts in the modeled Boussinesq results useful.
Modelers are to provide comparisons with the path positions and cross-shore velocity time series for the four configurations. Modelers are encouraged to discuss various parameter changes used during the comparisons, such as grid size, time step, friction, breaking models, material properties, and any initiation and stopping thresholds for debris motion.
