Summary
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 the basic knowledge on 3-D morphodynamic processes and the necessary know-how for utilizing these models are still insufficient. Hence it is concluded that there is an urgent need for modelling-oriented research on 3-D marine morphodynamics, but that it is too early to develop modelling facilities for practical application.
Zusammenfassung
Die vorliegende Arbeit befa\t sich mit der Frage, ob marine morphodynamische Modelle auch die DreidimensionalitÄt von Wasser- und Sedimentbewegungen berücksichtigen sollten und geht dabei auf die bestehende Nachfrage sowie auf den heutigen Entwicklungsstand der Modelle ein. Sie gelangt zu dem Schlu\, da\ zwar eindeutig Nachfrage nach solchen Modellen besteht und bereits geeignete Software- und SD-Modellkomponenten vorhanden sind, aber die Kenntnisse über 3D-morphodynamische Prozesse und die Anwendung solcher Modelle bisher unzureichend sind. Es wird daraus gefolgert, da\ ein dringender modellorientierter Forschungsbedarf zu marinen morphodynamischen 3-D-Modellen besteht, es aber für die Entwicklung von Modellen für die Praxis noch zu früh ist.
