Abstract:

A variety of mechanisms have resulted in the loss of coastal wetlands. Thin-layer disposal of dredged material has been proposed to maintain and restore wetland areas. Transport of this material into wetlands areas is problematic due to the sensitivity of the wetland environment. Hovercraft transport and distribution of dredged material has been proposed as an environmentally acceptable alternative to conventional transport methods. The objective of this study was preliminary evaluation of technical and economic feasibility of the use of hovercraft for dredged material transport and distribution in wetlands. Comparison was made to conventional transport alternatives.
