This dataset is part of the 2018 Belgian submission for the Marine Strategy Framework Directive (MSFD) linked to descriptor 7, criterion 1. This dataset describes the impact of an offshore windmills farm on the hydrodynamics in the Belgian part of the North Sea (BPNS). Originally, it is a NetCDF file with the results of the reference simulation made with the COHERENS (COupled Hydrodynamical Ecological model for REgioNal Shelf seas) hydrodynamic model only forced by tides (no wind effect). Model resolution : ~ 12.5m. It contains both the reference situation which is a simulation without any windmill and the modeling result of the influence by the windmills on the hydrodynamic in the BPNS. The dataset contains the results on the most inner nested grid level for one reference spring-neap cycle: - hourly sea surface elevation - hourly bottom shear stress - hourly 3D horizontal velocity components (u,v) - hourly 3D eddy viscosity - time-averaged bottom shear stress over the reference spring-neap cycle - percentile 90 of the bottom shear stress for the reference spring-neap cycle - percentile 90 of the specific kinetic energy at the sea bed - accumulated time during which sedimentation processes are dominant - accumulated time during which re-suspension processes are dominant.

The entities included in the dataset represent the physical network in the sense of the Inspire European directive. The dataset comprises several classes and is in accordance with the INSPIRE specifications. The Wetland class represents poorly drained or periodically flooded portions of land, the soil of which is saturated with water but where vegetation is nevertheless able to develop. The StandingWater class represents flooded areas that are, nevertheless, completely surrounded by land.

Top10Vector – Hydrography is the data set of the Belgian hydrography. This data set includes six classes. First class: waterway kilometre markers of the Belgian navigable waterways. Second class: watercourse surfaces. Third class: watercourse segments. Fourth class: water points, which means points where the water arrives at the surface or disappears into the subsoil. Fifth class: wetlands, which means zones where the soil is saturated or regularly flooded. Sixth class: water surfaces. This data set can be bought via the corresponding hyperlink.

CartoWeb.be is a Web Service (WMTS/WMS) containing cartographic representations covering 11 scale levels. CartoWeb.be offers a cartographic representation which has been developed specifically for on-screen viewing of the NGI’s most recent vector data sets. Three versions are available for the Belgian territory: 1) a TOPO layer containing a cartographic representation at all scales; 2) a GREY layer, which is the symbolisation in different shades of grey and blue of the TOPO layer. It constitutes an ideal map background; 3) an OVERLAY (1:2 500 - 1:25 000) layer destined to be used as an overlay on other data (orthophotographs for instance). This layer contains the symbolisation of a few layers only. A fourth layer, CROSSBORDER, is available in order to allow viewing (only on the smallest scales) the European context of Belgium. The extent of this representation is limited and could change in the following versions. It is best to combine the CROSSBORDER layer with the TOPO layer.
