The U.S. Army Corps of Engineers released the Louisiana Coastal Protection and Restoration (LACPR) draft final technical report in March, 2009. In response to federal legislation, the Corps had to analyze hurricane protection, and design and present a full range of measures to protect against a storm equivalent to a category 5 hurricane. The request included measures for flood control, coastal restoration, and hurricane protection, and stipulated close coordination with the State of Louisiana and its appropriate agencies. This is the second and final report from the National Research Council (NRC) Committee on the Review of the Louisiana Coastal Protection and Restoration (LACPR) Program. The committee was charged to review two draft reports from the LACPR team and to assess the hurricane risk reduction framework, alternatives for flood control, storm protection, coastal restoration, and risk analysis. This report presents this committee's review and advice for improvements of the LACPR March 2009 draft final technical report.

A computer-based decision-support tool, called the Coastal Protection and Restoration Authority (CPRA) Planning Tool, provided technical analysis that supported the development of Louisiana's Comprehensive Master Plan for a Sustainable Coast through CPRA and community-based deliberations. This document seeks to provide an accessible technical description of the Planning Tool and associated analyses used to develop the Master Plan.

This report was prepared for the U.S. Army Engineer District, New York, to evaluate shore erosion in response to construction of the Federal navigation project at Mattituck Inlet, NY, under the authority of Section III of the River and Harbor Act of 1968, Public Law 90-483, approved August 1968. The original navigation project was authorized in 1896 and modified in 1935 and 1964. The report is organized into seven chapters and two appendixes. Chapter 1 gives an introduction to Section III authority and the physical setting at the study site. Chapter 2 discusses shoreline change and change rates in the vicinity of Mattituck Inlet. Shoreline change rates are calculated for the region and compared for shorelines adjacent to the inlet. Chapter 3 describes numerical simulations of waves, wave-induced and tidal currents, and sediment transport pathways at the inlet. Chapter 4 develops the sediment budget for the site and region. Chapter 5 describes estimated future conditions without a project. Chapter 6 evaluates the responsibility of the Federal government for downdrift shore erosion, and Chapter 7 presents alternatives for mitigation. Appendixes A and B document analysis results for shoreline change.

There has been an exponential increase in desalination capacity both globally and nationally since 1960, fueled in part by growing concern for local water scarcity and made possible to a great extent by a major federal investment for desalination research and development. Traditional sources of supply are increasingly expensive, unavailable, or controversial, but desalination technology offers the potential to substantially reduce water scarcity by converting the almost inexhaustible supply of seawater and the apparently vast quantities of brackish groundwater into new sources of freshwater. Desalination assesses the state of the art in relevant desalination technologies, and factors such as cost and implementation challenges. It also describes reasonable long-term goals for advancing desalination technology, posits recommendations for action and research, estimates the funding necessary to support the proposed research agenda, and identifies appropriate roles for governmental and nongovernmental entities.
