Dynamics and analytical models of short-term coastal changes in the case of storms
Many occasions of violent coastal erosion along the coasts of Vietnam in the last years, especially the catastrophic destruction of the coasts of Thua Thien – Hue province, have presented themselves first of all as a direct consequence of powerful attack of storm waves upon the coastline plane. Repercussion of such attack is absolutely certain to create instantaneous crack of the coast, some big material masses have to split and separate from the coastline and either momentarily collapse right in front of collapsed position or hurl further in the wave acting direction. These dynamical processes make the coastline destroy quickly and move backwards to the main land, by that way and create a strong short-term change of the coast. In this paper the author wishes to present the dynamics of these processes and relative analytical models for numerical determining an individual broken material bodies when the waves rush to impinge upon the coastline plane during storms. Such calculations could be applied in the technical problems of shore-protection and relative basic investigation
