Environmental Windows Associated with Dredging Operations

Résumé du livre

This technical note summarizes the types of concerns that lead to requests for environmental windows for Federal navigation dredging projects in both marine and freshwater systems, as well as the frequencies of occurrence of these concerns among U.S. Army Corps of Engineer (USACE) Districts. The information presented is derived from responses received from a survey sent to all USACE District offices that perform operations and maintenance (O & M) dredging in either marine or freshwater environments. This note serves to update earlier surveys by LaSalle et al. (1991) for dredging operations conducted in coastal and Great Lakes areas and by Sanders and Killgore (1989) for seasonal restrictions associated with dredging operations in freshwater systems.
