Physical model tests on stability and interlocking of new breakwater armour block Crablock

This research focuses on the hydraulic stability and interlocking degree of single layer Crablock armour units. Physical model tests have been performed in the wave flume to determine the stability number. The behaviour of the units under wave attack is described by displacements, individual movement and rocking. Displacements and rocking were visually observed and the individual movement is determined from photo analysis. Also pull tests have been performed to determine the interlocking degree of Crablock. Pull tests have been done after exposure of waves and in dry conditions. An explanation about the values in the excel sheets can be found in the related publication: "Physical model tests on stability and interlocking of new armour block Crablock".
