Doesn the sand used to replenish the beaches simply get washed away during the next storm?
The sand put on a beach during replenishment is ‘sacrificial’. It is intended that some of it be washed away during the next storm. If this replenishment sand weren’t available to be eroded away, then beaches, dunes and foreshore reserves would be eroded instead. Much of the sand that is washed offshore during storms is washed back onshore during calmer periods, so it is not ‘wasted’.
