Beneficial use of dredged sediment to enhance salt marsh development by applying a ‘Mud Motor’

We test an innovative approach to beneficially re-use dredged sediment to enhance salt marsh development. A Mud Motor is a dredged sediment disposal in the form of a semi-continuous source of mud in a shallow tidal channel allowing natural processes to disperse the sediment to nearby mudflats and salt marshes. We describe the various steps in...

Experimental research on dynamic dredge overflow plumes

The overflow mixture of hopper dredgers contains fine sediment which when released in the environment forms a so-called plume. The spreading of this sediment and the related turbidity increase and sedimentation pattern can be of environmental importance. Understanding the behaviour of these plumes is therefore important. The first phase of the...
