Abstract:
There is a number of famous theoretical and experimental works that oriented themselves
to solve actual problem of coastal change, including the change of coastline, under versatile
influence of oceanic wind waves. In this paper the author would like to give supplementally
a few new behaviours of that phenomena observed along the coasts of Vietnam, such as
coastal collapse & primitive on-the-spot accumulation, material hurl, etc. Most simple
theoretical explanation of them grounding on the Newton's second law has been presented
and as results of that there appeared such notion as indicator and criterion which could be
used for demarcation of different behaviours in initial stage of general coastal changing
processes.
