LONG TERM BEHAVIOUR OF THE SEDIMENT VOLUME INSIDE A TIDAL BASIN AFTER POLDERING

Ernst Schroeder, Roland Goldenbogen, Hans Kunz

Abstract


The development ofmorphological reactions over time as a result of polderings has been investigated for the Dithmarscher Bucht (Bay of Dithmarsch), a tidal basin which is located in the North Sea/Germany. Two methods of parametrization have been used: the first method is based on volume-differences and the second one refers to the vertical differences of the topography. The results have been used for an estimation of the stability of the tidal basin with respect to an accelerated rise of the relative sea level.

Keywords
