Book Description
The problem of a vertical plane jet-plume in shallow water was investigated experimentally and analytically. The four distinct regions of flow are the jet-plume region, surface impingement region, internal hydraulic jump region and the stratified counterflow region. Only the first three were studied in detail. The experiments concentrated on the surface impingement and internal hydraulic jump regions. Velocity profiles and dye photographs were compiled for six runs. An additional 13 runs were done in which only dye photographs were taken. The velocity profiles and scale.data were then analyzed and plotted. The analytical portion of the study consisted of three parts. The first was the development of the plane jet-plume equations. The second part was a control volume type of analysis of the surface impingement region. This yielded an equation for the impingement depth of the surface layer. The third part was a momentum analysis of the internal hydraulic jump region. Two distinct equations were developed. The experimental data was compared to the predictions of the theoretical equations. The variations of the velocity and length scales were compared to the case of a plane non-buoyant surface discharge.

Book Description
The U.S. Environmental Protection Agency (EPA) was introduced on December 2, 1970 by President Richard Nixon. The agency is charged with protecting human health and the environment, by writing and enforcing regulations based on laws passed by Congress. The EPA's struggle to protect health and the environment is seen through each of its official publications. These publications outline new policies, detail problems with enforcing laws, document the need for new legislation, and describe new tactics to use to solve these issues. This collection of publications ranges from historic documents to reports released in the new millennium, and features works like: Bicycle for a Better Environment, Health Effects of Increasing Sulfur Oxides Emissions Draft, and Women and Environmental Health.

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.
