The natural behaviour of coastal seas and estuaries along the german North Sea as well as Baltic Sea coast is dominated by various phenomena.

Simplified schematic representation (available in PDF-format, 47k) of many important physical processes in estuaries. This graphical representation is available in Encapsulated PostScript (colour) format (105k) and Encapsulated PostScript (black and white) format (105k).

The relevant processes can be normally described using conceptual models written in the form of ordinary or partial differential equations. These equations are exact from a scientific point of view. On the other hand side they are only very simplified models compared to the complexity of the natural system under investigation.

The interested reader may find further information under the following link. The documents are provided by the University of the German Armed Forces (Bundeswehr) and are only in German available.


This page contains a comprehensive list which shows all the mathematical models currently used at the BAW-DH.
