Introduction

Welcome to E2-D2 (Environmental Effects & Dredging and Disposal). E2-D2 is a literature database comprised of technical references covering a diverse range of topics related to environmental effects of dredging and dredged material disposal projects. The database focuses on broad topics such as beneficial uses of dredged material, contaminated sediments, and effects of sediment resuspension and sedimentation on aquatic organisms and their habitats. Much of the technical literature pertaining to dredging and dredged material disposal is found in the "gray" literature, i.e., non-peer-reviewed federal or state agency publications, or proceedings of symposia and specialty conferences. Many other studies of dredging operations are documented in the form of unpublished contract reports frequently held in project files rather than libraries or archives.

A primary objective of E2-D2 is to facilitate searches for relevant references by providing a single source for this diffuse gray literature as well as important references in the peer-reviewed literature. A second objective is to make this information accessible to all interested parties, both within and outside of the Corps of Engineers. Accessibility is the underlying reason for locating this database on the Internet.

As currently configured, E2-D2 contains approximately five thousand references. Expansion of the database, will continue indefinitely. Submission of references not found in E2-D2 is encouraged. Provision of the complete document in digital format is preferred. Where copyright infringement is not an issue, or with appropriate waivers, complete documents can be added in downloadable format. Efforts to load large numbers at archived Corps-sponsored technical documents are ongoing, e.g., the Corps' Dredged Material Research Program (DMRP) series, which was concluded in 1979, the Disposal Area Monitoring System (DAMOS) series, and the Environmental Effects of Dredging Technical Notes, which are both ongoing. The database focuses on broad topics, such as beneficial uses of dredged material and effects of sediment resuspension and sedimentation on aquatic organisms and their habitats.

The database allows the user to perform simple queries for authors, titles, years, publications, conferences, journals, and keywords. Instructions are provided throughout the database for a user friendly experience.
