On-Demand Webinar: Seepage Rehabilitation for Embankment Dams
Association of State Dam Safety Officials, 2015
This webinar will review the current state of the practice for rehabilitation of embankment dams to address seepage issues. Seepage rehabilitation measures can generally be grouped into two categories: seepage reduction / limitation measures and seepage collection measures. Seepage reduction /limitation measures include such features as foundation grout curtains, low permeability blankets, and seepage barrier walls. These measures are intended to reduce or limit the amount of seepage that occurs through, beneath, and around a dam. Seepage collection measures include such features as blanket drains, toe drains, chimney filters / drains, and relief wells. These measures are intended to collect seepage which occurs in a manner that maintains stability of the dam and prevents internal erosion. All of these measures will be reviewed along with discussion of their appropriate applications. Case studies and examples will be used to highlight the applications of the various methods.
