Wave absorbers are used in wave basins to minimise the reflected wave height form the boundaries of the basin. This reports presents the results of a series of laboratory tests of permeable sloping absorber made of artificial horsehair material. They were carried out on the 0.9 m wide wave flume of the Water Research laboratory, UNSW. Results indicate that the employed absorber can be as effective as a beach absorber made of sand or gravel. The best performance was obtained for the minimum surface slope of the structure.
