Coastal Research Center

What Coastal Research Center does

Forschungszentrum Küste (FZK), also known as the Coastal Research Center, is a joint non-commercial research institution of Leibniz Universität Hannover and Technische Universität Universität Braunschweig, established in 1996 and headquartered in Hannover, Germany. Its operational centerpiece is the Großer Wellenkanal (GWK) — a Large Wave Flume built 1979–1983 with a usable length of approximately 300 m, width of 5 m, and depth of 7 m — which is one of the world's largest facilities of its kind for physical hydraulic modeling of waves, tidal currents, and their interactions with coastal and offshore structures.

The institution's technology platform was materially upgraded between late 2020 and summer 2023 via the BMWK-funded marTech project (35 million EUR), producing GWK+. GWK+ integrates a 7 m piston-type wave board with active absorption (max wave height ~3 m, stroke ~7.5 m), a current generation system capable of 20 m³/s flow with programmable tidal hydrographs, and a deep section with maximum bedding depths of ~6 m for soil-structure interaction studies. Measurement instrumentation is continuously expanded to capture complex wave-current-structure processes. These combined capabilities support research programs covering offshore wind foundation loading, scour and seabed interaction, floating structure stability, wave and tidal energy systems, and tsunami/storm surge loading.

FZK does not generate commercial revenue. It operates as a publicly funded research center, with funding flowing from federal ministries — primarily BMWK, BMBF (through DAM research missions including CoastalFutures at 5.5M EUR), and the German Research Foundation (DFG) — as well as from EU-level programs such as ESFRI via the MARINERG-i consortium. Customers are academic institutions, government agencies, and (via project partnerships) industry participants seeking large-scale physical model testing. Distribution is direct institutional collaboration rather than commercial sales; outreach runs through the FZK Colloquium series, the Forum Küstenforschung, peer-reviewed publications, and a multilingual website.

Revenue model

1. Public Research Funding: FZK operates as a publicly funded joint research institution of Leibniz Universität Hannover and Technische Universität Braunschweig. Core funding comes from federal and state government research grants. Project-specific funding has been secured from BMWK (35M EUR for marTech/GWK+ upgrade), BMBF (e.g., ~25M EUR for DAM research missions, 5.5M EUR for CoastalFutures), and DFG. Revenue is not commercial in nature; the center provides research services to the scientific community and governmental bodies.
2. Research Project Grants and Contracts: Competitive research funding awarded through national and European programs including ESFRI (MARINERG-i included on ESFRI-2021 roadmap), DFG priority programs (e.g., SPP1889 Sea Level & Society), and BMBF-funded DAM research missions. Funding supports specific collaborative research projects with multiple institutional partners.
