Stage-Frequency Data
I nformation leadi ng to a relationship between
the stage or elevation of the stream' s water
surface and the percent chance of occurrence
of t he flood caus ing it.
Standard Project Flood
The flood that may be expec ted from the more
s evere combinations of meterological and
hydrological conditions that are conside red
r easonably characterist i c of the geographical
area in which the dr ai nage basin is located,
excludi ng extremely rare comb inations .. Peak
discharges for t hese fl oods are generally
about 40 to 60 percent of the probable maxi mum
f loods for the s ame basin. Such f loods are
intended as practicable expressions of the
degree of protection that should be sought
in the design of f lood control works, the
failure of whi ch might be disas trous .
Structural Improvements
In t he context of f lood control , t he engi neering
construction for purposes of water r egulat ion,
control, storage or conveyance.
Time of Concentration
Time required for water to flow f rom the
hydraulically most remote point of a watershed
to the outlet or other point of
reference.
Water Sur face Profile
A graph of water surface elevations along
a stream for a given discharge or specified
f lood.
