The variation of the toe scours profile by the surface roughness
of a slope seawall was investigated experimentally in this
research. The effects of the roughness on the wave
characteristics, including the wave run-up on the slope, the
flow in the down-rushing wave and the wave reflection from
the wall, are also explored. Two types of the toe scours, named
the L-type and N-type, were performed in the experiments. It
was found from the experiments that the surface
roughness was potentially reducing the intensity of the down-
rushing flow and the wave run-up height, even the reflection of
wave. The maximum depth of the scours as well as the scouring
distance was thus reduced in the light of the surface
roughness. The scouring depth and the values of the wave
characteristics on the slope were descended obviously due to
the surface roughness, from comparing with the smooth surface.
However,these descended values were limitedly increased as the
surface roughness became larger.
