ABSTRACT
In Minden, a town in north-western Germany, a new lock is currently being planned to connect the country’s longest waterway, the Midland Canal with the river Weser overcoming a water level difference of around 13 m. The Department of Geotechnical Engineering at the Federal Waterway Engineering & Research Institute in Karlsruhe (BAW) has been involved in the planning of the new lock. In this paper the set up of a 3D groundwater-model (saturated/unsaturated) for the analysis of the effects of the dewatering on groundwater flow around the excavation will be presented. Figure 1 gives an overview of the existing lock and the future excavation pit for the new lock.
