Abstract. The Coastal Observing System for Northern and Arctic Seas (COSYNA) was established in order to better understand the complex interdisciplinary processes of northern seas coasts a changing environment. Particular focus is given German Bight North Sea as prime example heavily used coastal area, Svalbard an coast that under strong pressure due global change.The COSYNA automated observing modelling system designed monitor real-time conditions provide short-term forecasts, data, data...

Abstract. Results of long-term measurements CTD, current velocity, turbidity, and dissolved oxygen from three stations in the mouth Elbe Estuary northern Germany are presented for period 2012 2013. The focus is on a station named HPA-Elbe 1, which part COSYNA coastal observing system arctic seas, but data two neighbouring also comparison to bridge gaps time-series 1. variations variables exhibit distinct tidal patterns related longitudinal estuarine gradients water constituents local...
The nautical bottom (i.e., the level at which contact with a ship's keel causes either damage or unacceptable effects on controllability and manoeuvrability of ship) should be associated to measurable physical characteristic. Bulk density is typically used as criterion for by many ports worldwide. However, rheological properties particularly yield stress mud are eventually more suitable parameters defining due their strong correlation flow navigability. density-yield depends significantly...
Measurements of wave transmission at two trapezoidal submerged structures are analysed and discussed with respect to the design formula d'Angremond et al.. Transmission coefficients agreed well within given range validity, however, an appropriate crest height width from rubble mound surface has be used. Special interest been put on results beyond upper limit formula, e.g. relatively high water levels, variation in mean transmitted periods, some numerical modelling.
Within the framework of different EU research projects (THESEUS and TIDE), investigations efficiency artificial sandbanks in mouth Elbe estuary for mitigation tidal energy a better storm surge protection were carried out. The was analysed by means two- three-dimensional hydro- morphodynamic models. models calculate water level current velocities as well transport dissolved constituents under mean conditions. To allow investigation effects on currents inner estuary, high spatial grid...
Large parts of the tidal estuary river Elbe (Germany) are characterized by regular patterns sand dunes. They presumed to evolve due complex transport mechanisms and show multi-faceted migration patterns. Direction magnitude their influenced hydrodynamic boundary conditions such as runoff tides. Dune Migration can lead residual rates, depending on its direction dune's characteristics. The understanding dune associated is basis an effective sediment management well important requirement for...
Large container ships approaching harbours via tidal rivers create strong currents and large ship waves. In the Elbe estuary near Port of Hamburg with a range about 2,85 m century old protection embankments show undulate shape even after frequent restoration. Analysis origin deformed embankment protections was done considering wind waves, waves flow conditions from varying river discharges flows by using numerical physical models which were calibrated local field measurements. The vary...
Tidal flat areas in estuaries are affected by strong morphodynamics. Changes of sedimentation and erosion occur on different temporal spatial scales. These changes challenge the responsible authorities due to high importance sufficient navigation channel depths ecological those unique zones. In cooperation with Hamburg Port Authority University Technology runs broad field measurements tidal Elbe estuary. The results provide a fundamental data set improve knowledge about morphodynamic...
For future strategies in water depth maintenance the Port of Hamburg, determining navigability limit (i.e. nautical safe depth) is major importance. this purpose, a project "Nautical Depth" was set up at Hamburg Authority (HPA), which dedicated to dealing with issue. The aim measure under various boundary conditions and identify limits for passage high concentrated soil suspensions. Among other things within monitoring data suspended sediment fluxes from multibeam echo-sounders sub-bottom...
