Environmental Effects of Dredging: Building, Developing, and Managing Dredged Material Islands for Bird Habitat.

摘要

This note describes the environmental considerations and techniques that have been developed and tested for building, developing, and managing dredged material islands for use by birds for nesting and other life requirements. The text of this note was taken from lectures presented from 1979 to 1986 at the Dredging Short Courses held each year by the Texas AM University Center for Dredging Studies and from information compiled for Engineer Manual EM 1110-2-5026 entitled 'Beneficial Uses of Dredged Material.' One hundred years of dredging and open-water disposal operations by the Corps of Engineers (CE), state agencies, and private enterprise has resulted in the creation of over 2000 man-made islands throughout US coastal waters, riverine waterways, and the Great Lakes. The CE continues to maintain an interest in developing such islands because of its responsibility in using environmentally acceptable disposal methods and sites, the increasing shortage of upland disposal sites, the need for wildlife habitats in waterway areas, and the islands' recreational potential.
