3.8.2 Phenomena of littoral drift
A wave from Deep Océan characterised by its height, H and length, L
when moves towards the shore, its length initially undergoes a réduction
till the wave reaches a depth of nearly 0.16 times its length. Thereafter, the
wave height starts increasing until the water depth is about 1 to 1.5 times
the water height. The cross-section of sédiment transport mechanism is
brought out in Fig. 3.11.
