A few examples relevant to coastal engineering practice have been discussed in this section. Other examples are:
- Siltation of (dredged) navigation channels;
- Erosion near toe of breakwaters, sea-walls or offshore structures;
- Structural / gradual erosion of coasts;
- Impact of coastal protection tools, like groynes, offshore breakwaters and sea-walls and revetments;
- Behaviour of artificial beach and shoreface nourishments;
- Blockage of sediment supply by a river.
In all cases sediment transports due to waves and currents are important. Compared to sediment transports due to currents alone (like in rivers), the waves enhance the sediment transport and make the calculation of the transport rates more complicated. In Ch. 6, sediment transport due to waves and currents is discussed in detail.
