Digital Elevation Model (DEM) from 1280 to 2120 water depth at 40 meters resolution. Bathymetric surface collected during the oceanographic cruise JAMMEGAIA22 on board of the R/V GAIA BLU by CNR.

A bubble Barrier that removes litter from rivers is being applied in the Ave estuary (Portugal) in the framework of the MAELSTROM Project. In order to identify the location where the technology could possibly best be applied and to assess the impact of the litter removal on marine life, MAELSTROM makes use of numerical models. Facing the limited field data and absence of available models, we carried out field campaigns, set-up a hydrological model for the Ave river basin and set-up a hydrodynamic model for the estuarine region. The hydrodynamic numerical model for the Ave estuary was implemented using D-Flow Flexible Mesh (D-Flow FM), which is the hydrodynamic module of the Delft3D Flexible Mesh Suite developed by Deltares (for more information see the project deliverable D2.2 Numerical modelling and field campaigns to support litter removal at the demo sites).
