TrilaWatt: Bathymetry (2005-2020)

Definition: “Bathymetry” means the measurement of the topographical shape of the sole of a water body. The term is also often used — analogous to the word “topography” — synonymous with the shape of the water sole. Waters in this context are seas, rivers or closed inland waters. As part of the TrilaWatt project, bathymetric data sets are those representing the elevation distribution in the 12 nautical mile zone, including the estuaries of Ems, Weser and Elbe. Through morphological activities of the water soil, such a bathymetric model is only valid for a certain period of time or time. Data generation: The basis for bathymetric products are gridded bathymetric models, which are created using the Functional Ground Model, a data-based hindcast simulation model, via spatial-time interpolation methods from a database of sea and land surveys of various data types. For selected years from 2005 to 2020, a gerasterised bathymetric model will be created in 10 m resolution (and additionally partially in 1 m resolution) for the trilateral Wadden Sea. Product: A 10 m (or 1 m) grid of the trilateral Wadden Sea valid on 01.07. for selected years from 2005 to 2020, with each grid node lying down the height. The product is provided in GeoTiff and Shapefile format. English: The open-access TrilaWatt (Digital hydro-morphological twin of the Trilateral Wadden Sea) data collection describes the geomorphology, surface sediments, hydrodynamics, waves, tidal characteristics, sea water salinity, sea water temperature, and suspended sediment concentration within the trilateral Wadden Sea area. This metadata set describes and refers to the Bathymetry products of the data collection.
