Portuguese term or phrase:fuseplug
assessed a number of spillway upgrade options at XXX Dam to pass the PMP Design Flood. Options assessed included construction of a tertiary spillway, raising of the secondary embankment and provision of a fuseplug spillway.
Explanation: This is another option to using the term emergency:
In order to reduce the likelihood of a dam failure, consideration should be given to constructing a separate emergency fuseplug spillway (or auxiliary spillway) to carry part of the spillway discharge at maximum flows.
As the flood increases in size and exceeds the capacity of the dam's standard spillway, the fuseplug is overtopped and washes out. For the maximum probable flood, both the standard dam spillway and fuseplug spillways will discharge at the design discharges.
