The controlling effect of longshore sand transport was investigated by the numerical simulation using the BG model, when various types of groins were installed on a coast composed of two grain size populations. It was found that groins of low-crown height and submerged-type groin are ineffective to control longshore sand transport, because coarse sand (gravel) is apt to be selectively deposited near the shore-line, and thus sand will be easily transported away over the crown of the groins. Furthermore, groin with an opening at the landward end was less effective to control longshore sand transport. This condition corresponds to the case in which the shoreline retreats on an erosive coast, resulting in the formation of an opening at landward end of the groin.
