This book was released on 2008-02-08 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Mississippi River is, in many ways, the nation's best known and most important river system. Mississippi River water quality is of paramount importance for sustaining the many uses of the river including drinking water, recreational and commercial activities, and support for the river's ecosystems and the environmental goods and services they provide. The Clean Water Act, passed by Congress in 1972, is the cornerstone of surface water quality protection in the United States, employing regulatory and nonregulatory measures designed to reduce direct pollutant discharges into waterways. The Clean Water Act has reduced much pollution in the Mississippi River from "point sources" such as industries and water treatment plants, but problems stemming from urban runoff, agriculture, and other "non-point sources" have proven more difficult to address. This book concludes that too little coordination among the 10 states along the river has left the Mississippi River an "orphan" from a water quality monitoring and assessment perspective. Stronger leadership from the U.S. Environmental Protection Agency (EPA) is needed to address these problems. Specifically, the EPA should establish a water quality data-sharing system for the length of the river, and work with the states to establish and achieve water quality standards. The Mississippi River corridor states also should be more proactive and cooperative in their water quality programs. For this effort, the EPA and the Mississippi River states should draw upon the lengthy experience of federal-interstate cooperation in managing water quality in the Chesapeake Bay.

Zimpfer and published by . This book was released on 1988 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: A study was conducted from late April through mid- July 1985 to evaluate habitat quality of revetment eddies in the Lower Mississippi River. Sites were established at three locations: river miles 372 (Natchez, Mississippi), 192 (White Castle, Louisiana), and 35 (Port Sulphur, Louisiana). At White Castle, samples were taken a 3-week intervals throughout the study. The Port Sulphur and Natchez sites were visited once in large May/early June. The White Castle eddy was a persistent feature of the river's hydrology. Flow rates were slower in the eddy, and upstream currents were always present at one or more nearshore stations. Variation in current speed and direction was greatest at the eddy's periphery. The Port Sulphur and Natchez eddies were less well defined, and current directions within the eddies were variable. Most water quality perameters were not significantly different between microhabitats. Drifting insects, particularly dipterans, were most abundant in the mainstream at high currents in April and May regardless of diel period. Zooplankton densities were highest during April when adjacent floodplains were inundated, declining with decreasing river stage. Larval fish abundance was not significantly related to habitat or current speed. (fr).

Book excerpt: The ultimate purpose of sediment studies is to develop a workable knowledge of the basic principles controlling the transport of sediment in the Lower Mississippi River and to apply this knowledge toward effective and economical stabilization works for flood control and navigation. The more immediate purpose of this report, however, is to present the data that have been collected and analyzed to date (1929-1974) and to show what trends exist in the quantities and sizes of suspended and bed sediments for the Vicksburg District.
