Chapter 9
Dredging and Disposal
Publication: Inland Navigation: Environmental Sustainability
Abstract
Dredging in the inland waterways is performed primarily with hydraulic pipeline equipment or mechanically by cable-suspended buckets. Dredging removes sediment from recent deposits in a navigational waterway (maintenance) or from a long-time natural state to create new navigation access. The dredging project is a function of site conditions, dredged material type and quantity, equipment availability, operations, and logistics for the discharge of dredged sediment. Special-purpose dredging systems have been developed during the last few years to pump dredged material slurry with high solids content and/or to minimize the resuspension of sediments. A long-term management strategy (LTMS), dredged material management plan (DMMP), or dredged material management strategy (DMMS) describes a plan for managing sediment removed during maintenance dredging. Although management of typical navigational dredged material allows for few design specifications, these specifications can be critical in managing the impacts and engineering for benefits, such as ecological function or flood protection.
