The discussion concentrates on several items including assessment of the longshore sediment flux, modeling the storm-induced deformations and seasonal changes in a coastal profile and also prediction of long-term coast behavior. Based on available data the method is recommended to compute the longshore discharge of the sand, gravel and pebble sediments. When modeling the shortterm storm-induced deformations, the process-based models are most preferable. In particular, the author’s model CROSS-P is applicable to sand, gravel and pebble coasts. However for greater time scales the approach using approximation of coastal profile with one or two concave curves is more effective. The corresponding author’s models developed to describe the seasonal changes and long-term evolution of coastal profile are discussed.
