URBAN PLANNING

In our cities, along the coastline and along rivers, protection against high water levels is important for our safety. Extensive knowledge of the hydrologic system is of paramount importance in developing infrastructure plans, in urban planning and in the construction and maintenance of coastal and flood protection structures, such as levees and dams. Groundwater models and innovative measuring methods help to improve our understanding of what is going on beneath the surface. Geophysical measurements, for instance, provide insight into soil stability. This is significant, for example, when decisions need to be made as to which levee locations require urgent reinforcement and where this is less urgent. Preparing soil maps of large sections of soil along and underneath a levee structure will help to make these decisions.

In addition, knowledge of the subsoil and hydrology is important as the construction of a levee, for instance, may affect the water system in the surroundings. The new Hondsbossche sea wall, to name one example, has an impact on the groundwater system up to far behind the dunes. We develop hydrogeologic models in order to provide advice on the design of new infrastructure and levees.
