Fuseplug Spillway
Fuseplug Spillway
Data for an erodible spillway. Up to a 3 stage failure mode spillway system is allowed.
Fuseplug Spillway Width
Length of fuseplug spillway in metres.
Surcharge Depth
Surcharge depth to initiate failure in metres.
Sill
Level of Spillway Sill.
Base
Level of base of spillway. This level is assumed to be the final failure level.
Weir Coefficient
Weir Coefficient used in Weir equation. The default value is 1.7.
Decay Rate
Lateral decay rate of failure in m/hr. The time to fail is interpreted linearly after failure commences. Failure occurs
laterally over full depth while water level above base RL.
Basin Tailwater
Tailwater
Contains data necessary when considering interconnected basins.
