Environmental Effects of Dredging. Managing Dredged Material Via Thin-LayerDisposal in Coastal Marshes

摘要

This technical note describes how dredged material can be successfully managed inan environmentally sound manner in marshes by placing it in layers of 5 to 15 cm. (Unless otherwise indicated, all layer thicknesses indicated in this report refer to material that has undergone postdisposal consolidation.) Environmental studies of this process and of the regulatory history of thin-layer disposal in marshes are summarized. General planning and monitoring considerations are described, including descriptions of the types of equipment used to place dredged material in thin layers in marshes. (MM).
