Selecting and Accommodating Inflow Design Floods for Dams   [open pdf - 1MB]

"In September 2010, the Federal Emergency Management Agency's [FEMA] National Dam Safety Program sponsored development of this document under the supervision of James E. Demby, Jr., P.E. of FEMA. During the initial phase of the study, research was completed regarding the history of the hydrologic design of dams as well as the current state of the practice. This effort included conducting a comprehensive survey of all state and federal dam safety agencies that own, regulate, and/or assist in the design or evaluation of dams and reviewing their current policies and guidelines. The findings of this research effort are summarized in FEMA P-919: 'Summary of Existing Guidelines for Hydrologic Safety of Dams' (FEMA, 2012). The main objectives of this document are to recommend appropriate procedures for selecting and accommodating the Inflow Design Flood for dams based on current and accepted practices and to promote a reasonable degree of consistency and uniformity among state and federal agencies. The wide variety of dams and watersheds require a variety of approaches that can achieve a reasonable balance of public protection, efficiency of evaluation, and efficiency of project operation."
