A. Interceptor drain - a drain that physically intercepts flow paths or fully penetrates water bearing strata. B. Pressure relief drain - a drain that produces an area of low pressure to which water will flow from adjacent areas of higher pressure. C. Filter material - a …
b. Basic requirements of an embankment dam. Dams are a critical and essential part of the Nation’s infrastructure for the storage and management of water in watersheds. To meet the dam safety...
The primary purpose of this document is to provide guidance for drilling in and near embankment dams and their foundations. Of special emphasis is the prevention of damage to the embankment, structures, and their foundations from hydraulic fracturing, heave, erosion, filter/drain contamination, or other mechanisms during drilling-related ...
The longitudinal transition embankment foundation condition is encountered where the alignment places the embankment alongside a hillside or where an existing embankment is to be widened. The newly placed fill tends to slide down the slope of the hillside or the existing embankment.

EMBANKMENT DAMS 219 sures within the embankment, (2) rapid drawdown of the reservoir from a high level, (3) earthquake shaking, or (4) deterioration of effectiveness of drains and other factors. Each of these conditions deserves careful attention when dam safety is evaluated.
Design procedures and concepts, with direction to appropriate chapters within Design Standard No. 13 - Embankment Dams for specific methods or analyses, are presented for both earth and rockfill dams. These guidelines are limited to design procedures for rolled-fill type construction.
