Modelling of the migration of tidal channels

With the advancement in the field of numerical models, the predictions of morphological developments in the tidal flats of the North Sea by the application of process based models are in our reach. In this study the predictive capability of a depth-averaged morphodynamic model in capturing the migration of a tidal channel on the German North Sea over a period of 10 years has been investigated.

Alternative measures for the improvement of the harbour entry conditions of Friedrichskoog, North Sea

The motivation for the investigation is the sedimentation of the entry to the harbour Friedrichskoog, North Sea, which is an unfavourable development for shipping and drainage of the hinterland. The investigation was conducted to evaluate the effectiveness of several constructive measures to improve the waterway situation by reducing sedimentation tendencies in the harbour entry and maintaining the inland drainage. To this end a morphodynamic model (Delft-3D) was developed and subsequently calibrated and validated with the help of field data.

Comparison of hydrodynamic models of the Baltic Sea (MUSTOK)

The study aims to compare the results of hydrodynamic simulations of a Baltic Sea model developed at FTZ on the base of the Mike-modelling system of the Danish Hydraulic Institute on the one hand with the operational model system of the North and Baltic Sea developed by the German Bundesamt für Seeschifffahrt und Hydrografie (BSH) on the other hand.

Numerical sensitivity studies on the physics of storm tides in the German bight, North Sea

The most relevant processes contributing to significant water level variations at the German North Sea coast are the tides, external surges, generated on the Northeast Atlantic, and surges generated by storms over the North Sea. If these processes occur in adverse combinations their effects might accumulate to scenarios of extremely high water levels. The aim of this study is to provide new insights into the nonlinear interactions between the different processes and to determine adverse process combinations.

Morphodynamic at Kieler Förde

Das Forschungsprojekt verfolgt das Ziel, die Auswirkungen von Strömung und Seegang unter Normal- und Sturmbedingungen auf die Entwicklung einer konzeptionell geplanten Strandaufspülung in der Kieler Innenförde zu simulieren und zu bewerten. Ferner soll geprüft werden, welche potentielle Effekte und Folgen abwandernde Sande einer solchen Strandaufspülung auf die daran angrenzenden Gebiete auftreten.

SYSMAR Integrated System for Cage Fish Farm Management

Pegametan Bay and Model Grids

In this project an integrated system for the sustainable environmental and socio-economic management of cage aquaculture in Indonesia was developed. The investigations were carried out within the bilateral cooperation SPICE “Science for the Protection of the Indonesian Coastal Environment”.

Influence of the wind drag coefficient in storm surge models

In hydrodynamic simulations the wind drag coefficient represents the effects of the sea surface roughness. It is closely related to the local wave field which is not always fully determined by the local wind. Accurate model-predictions of storm surge water levels along the coast remain difficult, and this is mainly associated with uncertainties regarding the variation of wind drag coefficients at high wind velocities. Wind drag formulations that are only a function of the wind, might therefore lead to inaccurate predictions of surge models.
