This brochure provides a summary of the information presented in FEMA P-484, Technical Manual: Conduits through Embankment Dams, including the effects of conduits on embankment dams, internal erosion and backward piping erosion, the factors that can lead to embankment dam failure, and best practices for conduits through embankment dams.
Today, tens of thousands of conduits through embankment dams in the United States are aging and deteriorating. Many of these conduits were poorly constructed and are not frequently inspected, if at all. With each passing year, deteriorating conduits pose an increasingly greater risk for developing defects that can lead to embankment dam failure. This technical manual provides procedures and guidance for best practices for the design, construction, problem identification and evaluation, inspection, maintenance, renovation, and repair associated with conduits through embankment dams. The technical manual is intended for use by personnel familiar with embankment dams and conduits, such as designers, inspectors, construction oversight personnel, and dam safety engineers. The technical manual includes more than 280 illustrative figures, 34 case histories, and an extensive glossary.
This technical manual provides procedures and guidance for best practices for the design, construction, problem identifcation and evaluation, inspection, maintenance, renovation, and repair associated with conduits through embankment dams. The technical manual is intended for use by personnel familiar with embankment dams and conduits, such as designers, inspectors, construction oversight personnel, and dam safety engineers. The DVD format includes an extensive collection of additional reading references.
This technical manual provides the procedures and guidance for best practices concerning the design, construction, problem identifcation and evaluation, inspection, maintenance, renovation, and repair associated with plastic pipe used in embankment dams. The manual provides in-depth analyses of loading conditions, structural design, and hydraulic design of plastic pipe, and is intended for use by personnel familiar with embankment dams, drains, siphons, and conduits, such as designers, inspectors, construction oversight personnel, and dam safety engineers.
