Abstract

This paper briefly reviews our knowledge to the year 2000 concerning the behavior of tidal inlets on littoral drift shores, with special reference to ebb and flood shoals and channels. Both are subject to high variances in accordance with weather and hydrodynamic climates. As tidal inlets are often developed commercially for port-entrances requiring greater depth than nature offers voluntarily, they are subjected to human attempts to improve depth and possibly also layouts. In this way humans interfere with nature's order, which may result in certain adverse effects including erosion on the downdrift side. Nature itself has developed certain bypassing procedures which may be improved by technical means. This paper mentions such improvements, including some innovative procedures, and suggests such measures to be tested. Relative cost figures are given.
