| All dams need adequate spillway capacity. Learn more at DamFailures.org |
The hydraulic performance of a spillway is a function of many complex variables. Analyses related to spillway hydraulics include:
- Reservoir Routing
- Spillway Approach Hydraulics
- Spillway Control Structures
- Spillway Chute Hydraulics
- Spillway Terminal Structure Hydraulics
- Cavitation
- Stagnation Pressures
