National Dam Safety Program: Research Needs Workshops: Seepage through Embankment Dams   [open pdf - 4MB]

"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."
