Three-dimensional modelling of the upper 30 meters of the Dutch subsurface.

GeoTOP is a detailed three-dimensional model of the upper 30 to 50 meters of the subsurface of the Netherlands. It provides the user with a cell-based description of the spatial variability of geological, physical and chemical parameters in the subsurface. In this way, GeoTOP provides a sound framework for subsurface related questions on groundwater management, land subsidence, natural resources, and infrastructural projects.
