Hydrology Calculations for Design Storms (SEDCAD4)
Runoff estimates were calculated for three scenarios
• A two times a single. 10-yr/24 hr Storm during Operations to determine the size of
ponds and the expected volume and flow rates during operations.
• A single 100-year/24 hr. Storm during operations to determine the design flow
capacity of channels and spillways
• A two times a single 10-yr/24 hr Storm after Reclamation to demonstrate the change
in flow and volume after closure.
