Morphodynamic Evolution of Dredged Sandpits

Evolution of Marine Morphodynamic Modelling: Time for 3-D?

The question whether it is time for marine morphodynamic models to take into account the 3-D nature of water and sediment motion is discussed starting from practical demand and the state-of-the-art in basic knowledge and model development. This leads to the observation that there is a clear practical demand, and that suitable software environments and some 3-D model components exist, but that t...

Morphodynamic models of communication

Morphodynamics means 'the dynamics of form', and the purpose of morphody-namic theories is to describe and explain the birth, evolution, and death of form. The term 'form' is used differently in different sciences, but the notions of discontinuity and organisation seems to recur in most uses. A central question is: how can continuous changes of an amorphous substance, such as increasing the vel...

Substratum heterogeneity of dredged vs un-dredged maerl grounds

Maerl grounds are formed from loose-lying, normally non-geniculated, coralline red algae (Corallinaceae). Such grounds are found in areas characterized primarily by high water movements in the photic zone. Maerl grounds form shallow marine biotopes of high biodiversity, analogous to kelp forests and sea grass beds, all of which are habitats created by marine phototrophs (Birkett et al., 1998; B...

Dredged Material Disposal Economics

Recent difficulties in siting dredged material disposal facilities are increasing interests in alternative disposal or reuse of dredged material and the possible adverse consequences of any increases in the generation of dredged materials. This paper focuses on economic aspects of these issues. Simple methods are suggested for evaluating the economics of increasing or decreasing the rate of dis...
