Abstract

Modelling of flows, sea level variations and bottom stresses in the coastal zone of West Estonia U. Suursaar, T. Kullas, & M. Otsmann Estonian Marine Institute, University of Tartu, Estonia Abstract Flow features and sea level variations were studied in the nearly tideless subbasins of the Baltic Sea, the Gulf of Riga and the Vainameri, using a highresolution (of order 1 km grid) shallow sea 2D hydrodynamic model. The model is forced by the wind stress calculated from single-point meteorological data, and the tide gauge sea level data applied along the open boundaries. The simulations based both on the realistic and idealistic forcing schemes were carried out. The aim of the study was to analyse circulation patterns during different meteorological conditions and to investigate the influence of currents, waves and sea level fluctuations on the littoral processes. In the Parnu Bay the high flow velocities, participating (along with storm waves) in the coastal erosion events, act 1.5-2 m above th
