Can a ‘Mud Motor’ of dredged sediment help enhance salt marsh development naturally?

Following the Building with Nature concept, a pilot study was conducted introducing finegrained dredged sediments as a semicontinuous source of mud into a shallow tidal channel, naturally dispersing sediment to nearby mudflats and salt marshes.

Can a lake’s ecology be restored with unwanted sediment?
Can a lake’s ecology be restored with unwanted sediment?

In collaboration with the Natuurmonumenten (the Dutch Society for the Preservation of Nature), Boskalis constructed the Marker Wadden. The archipelago situated within the Markermeer enables processes which revitalise the natural ecology.

How navigable are fluid mud layers?

Safe navigation through ports and waterways is determined by the space available under a ship's keel, but a seabed of fluid mud can get in the way.

Mud waves
Mud Waves

Mud waves may occur when the subsoil of a reclamation area is soft, with low shear strengths and can result in inadequate fill mass properties.

Uncertainty Analysis of the Mud Infill Prediction of the Oklng Approach Channel
Uncertainty Analysis of the Mud Infill Prediction of the Oklng Approach Channel

To take well-founded financial decisions, help manage risks and reduce uncertainty, a model for calculating the probabilistic assessment of maintenance dredging volumes was developed using the Olokola LNG project near Lagos, Nigeria, as an example.

15 Years Experience with Fluid Mud: Definition of the Nautical Bottom with Rheological Parameters
15 Years Experience with Fluid Mud: Definition of the Nautical Bottom with Rheological Parameters

In the contract of 1954 between the German Federal Waterways Administration and the newly formed Water and Land Federation Emden-Riepe, the Federation relinquished agricultural land within the Emden-Riepe Lowland to the Association of Port Operators to accommodate sediment from the Port of Emd.
