Coastal topo-bathymetric DEM for the Gironde estuary - upstream (TANDEM project)
The coastal topo- bathymetric DEM for the coasts of the Gironde estuary - upstream with a resolution of 0.0002° (~ 20 m) was prepared as part of the TANDEM project.
It covers an area around the Gironde estuary, its Atlantic mouth and extends to Bordeaux (Garonne river) and Libourne (Dordogne river). The DEM takes the form of two complementary grids: 1) Downstream estuary (from the Gironde river mouth to Pauillac); 2) Upstream estuary (from Pauillac to Bordeaux on the Garonne river, and to Libourne on the Dordogne river).
The DEM is designed to be implemented in the hydrodynamic models of the TANDEM project in order to estimate the coastal effects of tsunamis for the Atlantic and English Channel, where French nuclear power plants have been installed for about 30 years.
This product is available with the Lowest Astronomic Tide (LAT) or the Mean Sea Level (MSL) as a vertical datum.

- Statement
-
In addition to the Shom data, the surveys of external organisms have been exploited, the contributors of which are as follows: IGN, Grand Port Maritime de Bordeaux, Grand Port Maritime de La Rochelle, DDE, DDTM33, Port-Medoc.
- Description
-
The main tasks involved in producing this range of solutions are based on 4 key aspects, each intended to reduce uncertainty for the DEM:
1) collecting, evaluating, pre-processing and selecting data from multiple sources after acquisition using survey systems from various eras;
2) homogenising the vertical and horizontal datums for data sets;
3) using interpolation algorithms suitable for a heterogeneous distribution and the variable density of data, and
4) evaluating and qualifying the final product and preparing documentation.
