Protection of Transport Structures from Wave Action by Creating a Sandy Wave-Damping Beach

The design and operation of transport structures (railways, roads, bridges) located on the seashores in the zone of possible erosion by waves requires particularly careful consideration of shoreline protection measures. The article, using the example of a specific section of the Sambian Peninsula from Cape Taran to Cape Gvardeisky in Kaliningrad region, shows the problem of protecting a road running along the coast from wave action and suggests ways to solve it. The study describes results of laboratory studies on creation of a wavedamping sandy beach on the shores under conditions of material deficiency in the alongshore sediment flow. The research was carried out using the method of physical modelling in a wave basin. The research has proved the fundamental possibility of creating a local stable sandy beach to protect transport structures from wave action under the conditions of material deficiency in the alongshore sediment flow. The research results can be extended to other coastal sections of roads and railways.
