The water exchange in estuarine lakes of the southern Baltic Sea as on the Gardno Lake example

The study of the Lake Gardno uses methodology that enables to estimate a magnitude of the sea inflows, their conditioning and timing as well as frequencies of their occurrence in lake estuaries. A three dimensional hydrodynamic model was applied to the linked regions of the Baltic Sea and the Gardno Lake. The quantitative estimates allow verifying the previous calculations of the water balance including long term changes.
