The BAW (Federal Institute for Hydraulic Engineering) carries out extensive R&D studies (research and development) on climate impact research and the effects of planned expansion measures on sea shipping routes on behalf of the WSV (Federal Waterways and Shipping Administration). For this purpose, high-resolution three-dimensional numerical simulation models are used. The meaningfulness and quality of the simulation results is decisively dependent on the quality of the control at the model edges. The model topography (= "computing grid") and the hydrological conditions used on the model edges should represent an identical time period if possible. Since the model topographies for the model areas of the "Jade-Weser" and the "Elbe" model of the BAW were rebuilt in 2012, a measurement program was carried out in summer 2012 to record the hydrological boundary conditions. For this purpose, the BAW - Dienstort Hamburg has set up a measuring network of a total of 13 observation stations along the control edges of the numerical model systems. At least over the period of a "Nipp-Jump-Cycle" (~ 14 days) the following parameters were measured in different device configurations: CTD measurements (Conductivity, Temperature, Depth): - water level deflection (tide curve) - salinity - temperature - turbidity (partly) For the purpose of model validation, ADCP measurements (Acoustic Doppler Current Profiler) were carried out on an approx. 10 km parallel shifted edge into the model area: - Current and - Sea state measurements (in part). Where available, data from the gauge stations operated by the WSV have been included. DWD data is available for meteorological information (source: Deutscher Wetterdienst).
