Physical, Biological, and Chemical Inventory and Analysis of Selected Dredged and Disposal Sites, Middle Mississippi River.

Abstract

Sediments deposited in the channel by fluvial processes and material derived from the products of bank erosion pose a continuous dredging and disposal problem in the Mississippi River navigation system. Only a limited amount of data are available on the physical, chemical, and biological characteristics of the Middle Mississippi River as related to dredging and disposal operations. The study was undertaken: To provide background information on the physical, chemical, and biological characteristics of selected dredged and disposal sites; (2) to establish uniform procedures for sampling dredged material and biota in a riverine system; and (3) to describe the environmental impacts of dredging and disposal activities. Fifteen sites with prior histories of maintenance dredging and adjacent disposal operations and three river border areas with no history of dredging-disposal operations were sampled in September 1973.
