The History of Large Federal Dams


Book Description

This history explores the story of federal contributions to dam planning, design, and construction by carefully selecting those dams and river systems that seem particularly critical to the story. The history also addresses some of the negative environmental consequences of dam-building, a series of problems that today both Reclamation and the U.S. Army Corps of Engineers seek to resolve.




The Historical Archaeology of Virginia from Initial Settlement to the Present


Book Description

The book includes six chapters that cover Virginia history from initial settlement through the 20th century plus one that deals with the important role of underwater archaeology. Written by prominent archaeologists with research experience in their respective topic areas, the chapters consider important issues of Virginia history and consider how the discipline of historic archaeology has addressed them and needs to address them . Changes in research strategy over time are discussed , and recommendations are made concerning the need to recognize the diverse and often differing roles and impacts that characterized the different regions of Virginia over the course of its historic past. Significant issues in Virginia history needing greater study are identified.







Hydrodynamics and Water Quality


Book Description

The primary reference for the modeling of hydrodynamics and water quality in rivers, lake, estuaries, coastal waters, and wetlands This comprehensive text perfectly illustrates the principles, basic processes, mathematical descriptions, case studies, and practical applications associated with surface waters. It focuses on solving practical problems in rivers, lakes, estuaries, coastal waters, and wetlands. Most of the theories and technical approaches presented within have been implemented in mathematical models and applied to solve practical problems. Throughout the book, case studies are presented to demonstrate how the basic theories and technical approaches are implemented into models, and how these models are applied to solve practical environmental/water resources problems. This new edition of Hydrodynamics and Water Quality: Modeling Rivers, Lakes, and Estuaries has been updated with more than 40% new information. It features several new chapters, including one devoted to shallow water processes in wetlands as well as another focused on extreme value theory and environmental risk analysis. It is also supplemented with a new website that provides files needed for sample applications, such as source codes, executable codes, input files, output files, model manuals, reports, technical notes, and utility programs. This new edition of the book: Includes more than 120 new/updated figures and 450 references Covers state-of-the-art hydrodynamics, sediment transport, toxics fate and transport, and water quality in surface waters Provides essential and updated information on mathematical models Focuses on how to solve practical problems in surface waters—presenting basic theories and technical approaches so that mathematical models can be understood and applied to simulate processes in surface waters Hailed as “a great addition to any university library” by the Journal of the American Water Resources Association (July 2009), Hydrodynamics and Water Quality, Second Edition is an essential reference for practicing engineers, scientists, and water resource managers worldwide.




Delta Empire


Book Description

In Delta Empire: Lee Wilson and the Transformation of Agriculture in the New South Jeannie Whayne employs the fascinating history of a powerful plantation owner in the Arkansas delta to recount the evolution of southern agriculture from the late nineteenth century through World War II. After his father’s death in 1870, Robert E. “Lee” Wilson inherited 400 acres of land in Mississippi County, Arkansas. Over his lifetime, he transformed that inheritance into a 50,000-acre lumber operation and cotton plantation. Early on, Wilson saw an opportunity in the swampy local terrain, which sold for as little as fifty cents an acre, to satisfy an expanding national market for Arkansas forest reserves. He also led the fundamental transformation of the landscape, involving the drainage of tens of thousands of acres of land, in order to create the vast agricultural empire he envisioned. A consummate manager, Wilson employed the tenancy and sharecropping system to his advantage while earning a reputation for fair treatment of laborers, a reputation—Whayne suggests—not entirely deserved. He cultivated a cadre of relatives and employees from whom he expected absolute devotion. Leveraging every asset during his life and often deeply in debt, Wilson saved his company from bankruptcy several times, leaving it to the next generation to successfully steer the business through the challenges of the 1930s and World War II. Delta Empire traces the transition from the labor-intensive sharecropping and tenancy system to the capital-intensive neo-plantations of the post–World War II era to the portfolio plantation model. Through Wilson’s story Whayne provides a compelling case study of strategic innovation and the changing economy of the South in the late nineteenth century.

U.S. Marines In Vietnam: Fighting The North Vietnamese, 1967


Book Description

This is the fourth volume in an operational and chronological series covering the U.S. Marine Corps’ participation in the Vietnam War. This volume details the change in focus of the III Marine Amphibious Force (III MAF), which fought in South Vietnam’s northernmost corps area, I Corps. This volume, like its predecessors, concentrates on the ground war in I Corps and III MAF’s perspective of the Vietnam War as an entity. It also covers the Marine Corps participation in the advisory effort, the operations of the two Special Landing Forces of the U.S. Navy’s Seventh Fleet, and the services of Marines with the staff of the U.S. Military Assistance Command, Vietnam. There are additional chapters on supporting arms and logistics, and a discussion of the Marine role in Vietnam in relation to the overall American effort.
