Variant consideration flood protection in the City Port of Rostock

2022
AQUADOT Consultants, Hydraulic Engineering, Coastal Engineering, Port Consultan
City Port Rostock

In the course of the urban development of the city port of Rostock, the Hanseatic and University City of Rostock is planning, among other things, the renovation of the quay edge in the area of berths 86 to 91. In addition, the flood protection for the area is to be expanded to the current design flood level for public flood protection.

Currently there is a concept that emerged as the winning design in a planning competition, which provides for a permanent flood protection wall with a crown height of +3.54 mNHN on the waterfront with a cycle path on the land side. The construction with a height of 1.64 m above the ground would lead to a permanent separation of the water and land-side areas of the waterfront. This would reduce the width of the promenade area with a direct connection to the shore and the existing and new buildings on the land side of the protective wall, commercial buildings, especially with restaurants and indoor and outdoor seating, would be separated from the water. The task of the variant consideration carried out by the AQUADOT Consultants was to summarize the natural boundary conditions for planning flood protective measures in the City Port of Rostock, to discuss the present draft for linear flood protection, and to develop, discuss and evaluate further designs and routes with regard to technical, logistical and urban planning aspects.

Hanseatic Town Wismar

Within the port expansion planning of the Port of Wismar the terminal facilities of the 2nd construction phase will be extended in northerly direction. The planning considers mainly vertical quay wall constructions with sheet pile walls for the new berths 1A to 1D of the Port of Wismar as well as for the new quay berth of the Waterways and Shipping Authority Luebeck, branch Wismar, which substitutes the existing jetty.

Commissioned by the Port of Wismar the Competence Centre for Construction M-V in cooperation with AQUADOT examined the wave load in the planning area based on numerical / analytical calculation methods in the current situation as well as considering the planned quay wall layout and different kinds of structural wave load reduction measures. For assessment of reflection coefficients of different quay wall constructions physical model tests have been executed.

To secure safe handling conditions at the planned berths of the Port of Wismar and calm conditions at the facilities of the Waterways and Shipping Authority a preferred option for the layout of the planned quay constructions and wave protection was developed on the basis of the wave evaluations in the year 2011. In 2013, modified plannings have been checked with respect to wave loads at neighbouring mooring locations.

The Port Olpenitz GmbH is converting the former naval port Olpenitz near Kappeln into a holiday resort including a marina. The construction works include amongst others the raise of ground level elevation, construction of waterfront structures as well as renaturation measures.

AQUADOT supports the works by providing the design of sloped waterfront structures using locally available armour stones. Furthermore, AQUADOT reviews the influence of deconstruction of military and civil used installations on the protection level against flooding and coastal decline. Additionally, morphological changes at the beach Weidefelder Strand south of the project area is monitored yearly by AQUADOT.

Climate change bears the potential of a significant and persistent impact on technical infrastructure. The effects will probably be widespread and costly in contrast to influences of regionally and temporary acting extreme weather conditions. Therefore, early involvement of climate change aspects in planning processes is important to relieve expected resource constraints.

Initiated by the Hamburg Port Authority, AQUADOT worked out a guideline for port planners and authorities as well as terminal operators to identify relevant climate change impacts on and vulnerabilities of seaport development and operation. Furthermore, climate change adaptation measures in seaports are described in detail.

Traffic junction Senator-Borttscheller-Straße in the Port of Bremerhaven 2008

The port and terminal operators of the Port of Bremerhaven have invested and will invest in future considerable financial means to enable a smooth handling of current and predicted cargo. With the reconfiguration of the Osthafen new berths and additional operation area have been created. In 2010, the extension of the Kaiser Sluice to an effective width of 55 m and length of 305 m will allow the passage of modern RoRo ships. Furthermore, four new berths for container ships have been provided with the completion of the CT4 in autumn 2008.

Besides the waterfront works relevant measures on the landside of the terminals and the reorganisation of the hinterland infrastructure are necessary. This includes rearrangements on container terminals, concerning especially storage areas and loading facilities for railway and truck as well as construction of new administration and social buildings. Furthermore, the terminal hinterland connections have to be embedded in an overall traffic concept of the Port of Bremerhaven requiring amongst others shiftings and reallocations outside the terminal areas.

AQUADOT collaborated in the preparation of a port infrastructure concept for the Port of Bremerhaven with special respect to container traffic.
