Normally, nourishment takes place on the foreshore and backshore. However, nourishment of the inshore region is also a possibility (see Fig. 94). In the latter case, the sand is placed below water level. The waves then redistribute the sand over the entire beach profile. Inshore nourishment alone has seldom been performed. Yet, this method can be economical, since the sand is directly placed from the dredger without pipelines.
