Association of Dam Safety Officials

Monitoring programs provide the information necessary to understanding the on-going performance of the dam, as well as the ability to detect a change in this performance, which can be critical in identifying the need to take actions to avoid the consequences of a dam failure.

Effective energy dissipation of flows from outlet works and spillways is an extremely important component in dam safety.

Labyrinth weirs are widely used in spillway rehabilitation to upgrade existing dams to meet updated spillway design flood criteria. In addition to increasing discharge capacity, these weirs are also well suited to regulating upstream pool elevations for flood control or at intake structures.

The purpose of this webinar is to familiarize practitioners with the current state-of-the-practice in evaluating the stability of concrete dams.
