Filter and Drain Design and Construction Details
Eligible for 2 PDHs
Guidance on gradation design of filters for dams is available from several Federal agencies and is widely used, although often not fully understood. However, successful design and construction of filters and drains is dependent not only on appropriate gradation design, but also on a number of practicalities – filter compaction methods and requirements; filter and drain zone dimensions and placement methods; material sources for filters and drains; filter fines content; drain pipe configurations; drain pipe materials; among others. Sources of definitive guidance information on many of these practicalities are more limited and less widely understood and applied. This presentation will cover best practices for these topics and how filter design and construction details can influence the evaluation of internal erosion risk. Speakers
