Short summary

This work is focused on the impacts of climate change on a complex water flow system in the southeastern (SE) Baltic Sea, covering the Nemunas river basin and Curonian Lagoon. The results show that lagoon and sea will receive more water coming from the Nemunas. This will lead to a decreased frequency of saltwater inflow to the lagoon, and water will take less time to renew. Water temperatures in the entire lagoon and the SE Baltic Sea will increase steadily, and salinity values will decrease.
