Enlargement of the Juliana canal

The enlargement of the Juliana canal is planned to enable larger ships passing through. It envolves deepening and widening of the present canal bed. The canal bed is hydraulically sealed off from the surroundings by a 60 cm thick, artificial clay layer. This clay layer needs to be temporarily removed to attain the new bottom level.

The Water authorities of the Netherlands requested a groundwater model to evaluate the impact of the excavation works on the surrounding groundwater and surface water system. The stretch of canal where the works will be conducted was divided in 8 subareas with distinct hydrogeological characteristics and specific construction variables.
