The coast and the nearshore is a resource of extremely high value to the
Baltic States and a location of major conflict of interests by different
user groups. It is an important ecosystem that supports human wellbeing,
incl. providing food and recreational opportunities. It also has an
important commercial function, supporting trade, the movement of people,
and recreation through the beaches, ports and marinas. It is the buffer
between land and sea, with coastal erosion and integrity of the
nearshore ecosystem being a particular concern.

Solutions to current and future problems on natural and constructed
shorelines, eastern Baltic Sea
is financed from the European Economic Area (EEA) Financial Instrument
2014–2021 Baltic Research Programme (project EMP480).

This research brings together specialists from Tallinn University of
Technology, Latvian Institute of Aquatic Ecology, Klaipeda University
and Norwegian University of Science and Technology, each with their own
internationally recognized expertise, to provide solutions to the
current and future problems that already and will affect how we use
coastal resources.
The major source of energy to the nearshore are waves. Many of the
problems we experience (such as erosion and port siltation) relate to
how sediment (mainly gravel, sand and mud) is moved. Much current
knowledge comes from open ocean and cannot be directly applied to very
different conditions of the Baltic Sea. This research will provide
environmentally friendly solutions to coastal problems in ways that very
specifically account for the wave, water level and sediment conditions
in the eastern Baltic Sea and are transferable for all similar water bodies.
This is accomplished using i) data and knowledge that we currently have
to provide much better and higher resolution knowledge about waves than
are presently available, ii) by measuring sediment transport using novel
sensors developed at TalTech, iii) by applying the new knowledge to
examine how the interactions of waves and sediment impact the natural
shores and coastal structures, and iv) provide tools so that coastal
managers can make use of the knowledge produced to estimate how
vulnerable are single coastal sections.
