Selecting and accommodating inflow design floods for dams
Evaluation and Monitoring of Seepage and Internal Erosion.
(FEMA P-1032) This document presents a summary of current Federal practices for monitoring and measuring seepage, identifying potential failure modes (PFMs) related to internal erosion, assessing risk related to internal erosion, and remediating internal erosion.

This discussion will help the engineer to understand the differences between the two types of analyses and the appropriate cases for use of each.
Development and selection of appropriate shear strength parameters are thoroughly discussed with regard to loading condition and analysis type. The rapid drawdown loading condition section has also been expanded.
Chapter 4 Embankment Dams (Revised Draft Version) The Division of Dam Safety and Inspections, Office of Energy Projects, has provided more detail and has included additional practical dam safety information as well as information on dam safety experiences in Chapter IV, Embankment Dams of the Federal Energy Regulatory Commission, Office of Energy Projects, Division of Dam Safety and Inspections Dam Safety Engineering Guidelines.
The draft guideline, though not completed, is available for use and preliminary review.
Included in the chapter is a detailed review of "drained" and "undrained" analyses (formerly referred to as "effective stress" and "total stress" analyses).

Technical Manual: Overtopping Protection for Dams (FEMA P-1015) The National Dam Safety Program sponsored the development of a technical manual, in conjunction with the Bureau of Reclamation, to collect and disseminate useful and relevant information regarding the design, construction, and performance of overtopping protection alternatives for embankment and concrete dams (2014).
Filters for Embankment Dams - Best Practices for Design and Construction This document provides procedures and guidance for best practices concerning embankment dam filter design and construction, and represents an effort to collect and disseminate current information and experience having a technical consensus.
Brochure: Conduits through Embankment Dams: Best Practices (FEMA L-266) A brochure that summarizes the procedures and guidance for best practices associated with conduits through embankment dams (2005).
Technical Manual: Outlet Works Energy Dissipators (FEMA P 679) This manual will focus on the methods by which energy resulting from the release of water through the outlet works is dissipated for safe discharge downstream.(2010) Risk Prioritization Tool for Dams (FEMA P-713) The Risk Prioritization Tool for Dams is a standards-based decision-making tool for risk-based dam safety prioritization to be used by state dam safety regulators throughout the country to identify those dams within a large inventory that most urgently need attention and then allocate resources accordingly.
