This manual presents basic principles and technical procedures for hydrologic engineering analysis of flood damage reduction measures. This manual applies to HQUSACE elements, major subordinate commands, districts, laboratories, and field operating activities (FOA) having civil works responsibilities. Procedures described herein are considered appropriate and useable for hydrologic engineering analyses required for planning and design of flood damage reduction measures. Basic concepts and procedures for analyzing selected flood damage reduction measures are presented. Emphasis is placed on hydrologic engineering analyses required for economic evaluations and performance criteria associated with various measures. The manual overviews the planning problem, identifies requirements for properly sizing, locating, operating, and maintaining flood damage reduction measures. The without-project conditions and measure-specific requirements are defined. Appendices provide references to additional technical guidance and summarize computer program capabilities for meeting the plan evaluation needs.

Reducing flood damage is a complex task that requires multidisciplinary understanding of the earth sciences and civil engineering. In addressing this task the U.S. Army Corps of Engineers employs its expertise in hydrology, hydraulics, and geotechnical and structural engineering. Dams, levees, and other river-training works must be sized to local conditions; geotechnical theories and applications help ensure that structures will safely withstand potential hydraulic and seismic forces; and economic considerations must be balanced to ensure that reductions in flood damages are proportionate with project costs and associated impacts on social, economic, and environmental values. A new National Research Council report, Risk Analysis and Uncertainty in Flood Damage Reduction Studies, reviews the Corps of Engineers' risk-based techniques in its flood damage reduction studies and makes recommendations for improving these techniques. Areas in which the Corps has made good progress are noted, and several steps that could improve the Corps' risk-based techniques in engineering and economics applications for flood damage reduction are identified. The report also includes recommendations for improving the federal levee certification program, for broadening the scope of flood damage reduction planning, and for improving communication of risk-based concepts.

This thesis documents the development and application of a branch and bound enumeration algorithm for the selection of an optimal flood control plan. An application is presented in which optimal reservoir flood control plans for a three reservoir system are selected. Computer program HEC-5 is used to simulate the reservoir system to determine the modified condition flow-frequency curves, EAD is used to evaluate expected annual damage reductions and the HEC-DSS programs are used to manage the large amounts of data required for the computations. The branch and bound enumeration algorithm provides a systematic evaluation of plans with the HEC programs and expedites identification of the optimal plan by eliminating the need to evaluate all alternative plans.
