The Federal Emergency Management Agency (FEMA) has released a technical manual that investigated the internal erosion occurring at embankment dams and levees and how it poses a threat of failure and potential risk to public safety. Evaluation and Monitoring of Seepage and Internal Erosion (FEMA P-1032), sponsored by the Interagency Committee on Dam Safety (ICODS), provides procedures and guidance for “best practices” concerning the evaluation and monitoring of seepage and internal erosion. It also outlines possible emergency response actions for short-term risk reduction and long-term mitigation approaches. P-1032 is the culmination of efforts from FEMA, the US Department of the Interior’s Bureau of Reclamation, the Federal Energy Regulatory Commission, the Natural Resources Conservation Service, and the US Army Corps of Engineers.
