Tropical Storm Alberto Heavy Rains and Flooding, Georgia, Alabama, Florida, July 1994


Book Description

The United States Government Printing Office (GPO) was created in June 1860, and is an agency of the the U.S. federal government based in Washington D.C. The office prints documents produced by and for the federal government, including Congress, the Supreme Court, the Executive Office of the President and other executive departments, and independent agencies. The Coastal Zone Information Center (CZIC) collection provides access to nearly 5,000 coastal related documents that the U.S. Government Printing Office (GPO) received from the National Oceanic and Atmospheric Administration (NOAA) Central Library. The collection provides almost 30 years of data and information crucial to the understanding of U.S. coastal management and NOAA's mission to sustain healthy coasts. This is one of their documents.










Non-Conventional Energy in North America


Book Description

Non-Conventional Energy in North America: Current and Future Perspectives for Electricity Generation provides an analysis of the current state of non-conventional energy sources used in the United States and Canada. The book works through all non-conventional renewable energy power sources, such as solar, wind and nuclear, considers the associated pros and cons, their impact on society, the climate and the population, and their potential. As well as coverage on the amount of power generated from each source, this book considers various imposed policies and programs alongside public opinion to provide readers with an understanding of current and future potentials for sustainable energy. Readers in government, energy experts, economists, academics and scientists will find this book to be a great reference on which types of power generation they would like to develop in their regions to promote economic and social development. The book will equip readers with the knowledge to make future decisions to diversity the energy mix in their respective regions. Includes information on the different types of non-conventional energy sources in the USA and Canada, analyzing their impact on climate and the population Presents the pros and cons of each power generation technology, along with public opinion Features policy and programs currently in force in the USA and Canada on each type of non-conventional energy source




Enhanced Abutment Scour Studies for Compound Channels


Book Description

Experimental results and analyses are given in this report on bridge abutment scour in compound channels. Experiments were conducted in a laboratory flume with a cross section consisting of a wide floodplain adjacent to a main channel. The embankment length, discharge, sediment size, and abutment shape were varied, and the resulting equilibrium scour depths were measured. Water-surface profiles, velocities, and scour-hole contours were also measured. In the report, a methodology is developed for estimating abutment scour that takes into account the redistribution of discharge in the bridge contraction, abutment shape, sediment size, and tailwater depth. The independant variables in the proposed scour formula are evaluated at the approach-channel cross section and can be obtained froma one-dimensional water-surface profile computer program such as the Water-Surface Profile Program (WSPRO). The proposed scour evaluation procedure is outlined and illustrated, including consideration of the time required to reach equilibrium scour. The proposed methodology is applied to two cases of measured scour in the field.
