Understanding and Managing Plant & Animal Intrusions in Embankment Dams and Levees: On-Demand

Plant and animal intrusions represent a common but often overlooked threat to the long-term safety of embankment dams throughout the U.S. In fact, these hazards have been attributed to dam failures and near dam failures in the past. Proper identification, treatment, and long-term management of these dangers are important to the overall health of embankment dams. This webinar will provide engineers, owners and dam safety officials with an understanding of these concepts to help everyone participate in the safety of embankment dams.

This webinar will cover both plant and animal intrusions in embankment dams. Topics covered include: the identification and diagnosis of problematic situations; typical treatment methods; and strategies for preventing problems in the future.
