The laboratory tests are performed in a 10m long oscillating water tunnel with a vegetative meadow made from eelgrass mimics. The water tunnel can be set-up with either a sediment bed or a vegetative canopy and the water can be run as unidirectional or oscillatory. The results presented here are for both a sediment bed and a vegetative canopy in still and unidirectional flow. We present statistics for where cylidrical model eelgrass seed particles are most likely to settle given various vegetation patterns, seed release points, and water conditions.
