ResumoFlow features are studied in the NE part of the Gulf of Riga using a 2D hydrodynamic model forced by the wind and sea level data of 1999 as well as by some constructed stationary winds.Two flow patterns dominate in the Pärnu Bay.The most frequent of them has an inflow along the Liu and Tahkuranna coasts and an outflow along the trunk zone of the bay.Eastward motions predominate both in the Kihnu Strait and Valgerand.High flow velocities, participating (along with storm waves) in coastal erosion events, act 1-2 m above the average waterline and about half of the year's summary work of the flow by charging the coast is done during the 2-3 most stormy days of the year in the Pärnu Bay.
