Erosion/Energy Dissipation
From ASDSO Dam Safety Toolbox
The terminal end of an outlet works must be designed to resist erosion. Should the decision be made to rehabilitate a dam, lack of consideration of erosion in the stilling basin could result in damage to a newly installed system.
Types of Erosion
- Headcuts in stream can lead to failure
- Erosion that cuts into the toe of dam can cause embankment instability
