Shoreface profile dynamics in different time scales

Leont’yev I.O.

Dynamics of the sea coast is characterized by both the short-term changes and the long-term trends mani-‎fested in the time scales of decades, centuries and milleniums. When modeling the short-term storm-induced ‎deformations the process-based models turn out to be most successful as those simulate the suite of primary ‎mechanisms responsible for sediment transport and bed deformations. Presented model CROSS-P is ‎applicable to calculate the storm-induced deformations on sandy coasts of the seas, large lakes and water ‎stores. To analyse the long-term coastal evolution the model SPELT is suggested determining the position and ‎form of the profile depending on changes in sea level and imbalance of sediment budget.
