This document attempts to condense and summarize the vast body of existing information, provide a clear and concise synopsis of this information, and present a recommended course of action. This document is intended for use by personnel familiar with embankment dams and conduits, such as designers, inspectors, construction oversight personnel, and dam safety engineers."
