Designing Spillways to Mitigate Failure Modes: On-Demand

This course will present potential failure modes for chute spillways and ways to design these spillways to minimize the potential for failure.

Key Takeaways:

1. Understanding of failure modes such as cavitation and hydraulic jacking that can affect chute spillways.
2. Evaluation of potential spillway design and construction details that could lead to failure modes.
3. Evaluation of potential spillway failure modes.
4. Understanding of design details that can help prevent spillway failures.
5. Importance of our concern for spillway chute failures.
