%X Rainfall records of rainfall station including the
rainfall potential per hour and rainfall mass of five heavy storms are
explored, respectively from 2001 to 2010. The rationalization formula
is to investigate the capability of flood peak duration of flood
detention pond in different rainfall conditions. The stable flood
detention model is also proposed by using system dynamic control
theory to get the message of flood detention pond in this research.
When rainfall frequency of one hour rainfall duration is more than
100-year frequency which exceeds the flood detention standard of
20-year frequency for the flood detention pond, the flood peak
duration of flood detention pond is 1.7 hours at most even though the
flood detention pond with maximum drainage potential about 15.0
m3/s of pumping system is constructed. If the rainfall peak current is
more than maximum drainage potential, the flood peak duration of
flood detention pond is about 1.9 hours at most. The flood detention
pond is the key factor of stable drainage control and flood prevention.
The critical factors of flood disaster is not only rainfall mass, but also
rainfall frequency of heavy storm in different rainfall duration and
flood detention frequency of flood detention system.
