Research Workshop-Seepage535.jpg

Seepage through Embankment Dams (FEMA 535) 
Report from a FEMA workshop held October 17-20, 2000 in Denver, CO. This workshop report documents expert consideration of (1) potential seepage problems and solutions associated with penetrations through embankment dams, e.g., outlet works conduits; (2) filter design criteria and observed performance; (3) inspection of dams for detection of seepage problems, failure modes associated with seepage and internal erosion, and analysis of risks associated with seepage and internal erosion; (4) investigation of seepage problems and concerns at dams, including the use of geophysical techniques, and instrumentation and measurements for evaluation of seepage performance; (5) remediation of seepage problems through cutoff, reduction of flow, and collection and control of seepage, including the use of geosynthetics; and (6) impacts of the aging of seepage control and collection system components on seepage performance

Research Paper-EmbankmentDamFailureAnalysis.jpg

Embankment Dam Failure Analysis (FEMA 541)
Synopsis of findings from a research workshop held June 26-28, 2001 in Oklahoma City. (2005)


FEMAP-1016.jpg

Summary of Existing Guidelines for Hydrologic Safety of Dams 
The purpose of this report was to document the available data and to present the state of the practice for evaluating the hydrologic safety of dams, including inventorying current practices used by state and federal agencies.  This work included a review of hydrologic guidelines currently used in each state and federal agency that regulates dams, and was guided by an independent steering committee and reviewed by the Research Work Group.  A subsequent publication will include new federal guidelines for the evaluation of the hydrologic safety of dams that could be applied nationwide.
