Completely updated and with three new chapters, this analysis of river dynamics is invaluable for advanced students, researchers and practitioners.
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.
This working manual covers everything from theory, practical design, templates, installation, filling, equipment, maintenance to removal. With the combination of the TVA Technical Monograph 75-Steel Sheet Pile Cofferdams on the Rock manual and the US Corps of Engineers manual - Theoretical Manual for Design of Cellular Sheet Pile Structures our Cellular Cofferdams handbook make for an excellent reference book. Cellular Cofferdams, the large, barrel-like, interconnected structures formed of steel sheet piling and filled with coarse soil. Generally utilized for dewatering large construction sites as well as building piers, quaywalls, bulkheads, breakwaters and artificial islands. Over the years, a few papers on design theory have come forth, but only one complete publication devoted to the entire subject.
This manual provides guidance on evaluating the condition of the concrete in a structure, relating the condition of the concrete to the underlying cause or causes of that condition, selecting an appropriate repair material and method for any deficiency found, and using the selected materials and methods to repair or rehabilitate the structure. Guidance is also included on maintenance of concrete and on preparation of concrete investigation reports for repair and rehabilitation projects. Considerations for certain specialized types of rehabilitation projects are also given.
"Henry Peter Bosse (1844-1903) is now recognized as the leading photographer of the Mississippi River during the late nineteenth century: he extensively photographed the Upper Mississippi from 1883 to 1893, a time of unprecedented environmental and social change. His work was practically unknown until five separate volumes of his photographs were discovered within the past decade. Since then, his photographs have been exhibited at the Smithsonian and other national museums and purchased by private art collectors around the world." "Views on the Mississippi brings together for the first time almost one hundred of Bosse's most stunning images. These photographs, tracing the river from Minneapolis to St. Louis, capture the Mississippi as it was being transformed from an untamed natural wonder to a modern commercial highway. Presenting wagon and railroad bridges, towns and villages along the banks, and the steamboats that served them, Bosse's photography depicts the river at the fulcrum between the nostalgic, romantic era recorded by Mark Twain and the coming century of industrial development and environmental alterations (the navigation projects of the Army Corps are among the changes documented by Bosse). Also included is a detailed reproduction of Bosse's rare landmark map of the river, first published in 1887-88."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.
