H3D multiband grid

Flanders is composed of an alternation of aquifers (sand, gravel, chalk, rock, etc.) and non-aquifers (e.g. clay). The sequence of these aquifers and aquitards was modelled in Flanders in the 3D hydrogeological model of Flanders (H3Dv2). The hydrogeological 3D model (H3Dv2) was modelled at 3 different levels of detail: main units, sub-units and base units. This grid model combines the different individual grids of the H3Dv2 model in a single grid file with the base layers in mTAW of the individual main, sub- and base units in the different bands.
