River typology in Germany
General description

All the information on the German stream typology was taken from an official German website for the implementation of the Water Framework Directive called "WasserBLIcK" in April 2010 (http://www.wasserblick.net/servlet/is/18727/?lang=en). Please note that the German stream typology slightly changed in 2008 but the English version was not updated, yet.
A description of these changes is available in German in Pottgiesser and Sommerhäuser (2008).
