The Mud Motor is built by disposing the dredged mud at a specific location from where the mud is transported by natural processes, such as tidal flow, to nearby salt marshes. The mud is used as a natural building material for the salt marsh. This strategy reduces the recirculation of dredged sediment and it stimulates the growth of salt marshes.<\/p>\n <\/div>\n <\/div>\n

Traditional approaches to reduce the maintenance dredging involve disposal of dredged sediment at a location far enough offshore to limit the recirculation of dredged sediment. Other options are to dispose the dredged sediment onshore or to sell it.Traditional approaches to stimulate the development of salt marshes commonly involve structures to protect the salt marshes against waves and high tidal flows. The structures provide calm water in salt marshes and mud flats, which enables settling of the mud and growth of vegetation. <\/p>\n <\/div>\n <\/div>\n\n<\/div>\n\n
