Modelling of shoreface nourishment in the Lithuanian nearshore of the Baltic Sea
Jūratė KRIAUČIŪNIENĖ, Brunonas GAILIUŠIS, Erika RIMAVIČIŪTË

Various measures have been used to protect coastal areas controlling beach erosion. During the last decades, all over the world there has been a gradual change from engineering to soft coastal defense techniques, among which artificial beach nourishment is particularly popular. This study evaluates the suitability of the shoreface nourishment, when borrow materials are placed to form a nearshore berm, for the Lithuanian coast of the Baltic Sea. The analysis is based on the results of the MIKE 21 modeling system for sediment transport, bottom erosion and dynamic equilibrium processes under varying climatic conditions, first of all in stormy weather that has the major impact on hydrodynamic and sediment processes. The current study aims to demonstrate the importance of the nourishment project assessment prior to its actual implementation and to provide an example of methodology for such an assessment which demonstrates the importance of climatic data and possibilities of modelling.

Keywords: sediment transport, shoreface nourishment, MIKE 21 model, Baltic Sea
