AbstractA laboratory program was carried out to measure the loads and seabed response due to a buoyant ice block scouring a representative seabed. The results complement previous experimental data carried out at the Canadian Hydraulics Centre, which used a rigidly affixed ice block to scour seabed material representative of the Grand Banks region. The present study used the same seabed material; however in this test series, the model was towed along an ice tank, free to move throughout the water column. Seven tests were carried out. Freshwater ice, built up into a large block with an overall dimension of 0.76m x 0.76m x 0.71m, was used to scour the seabed at depths up to 0.2m. The scouring loads, displacement and angular movements and resulting trenches were measured. This report provides a description of the test arrangement and the experimental results.
