| Abstract | Flocy model . The model is
developed to calculate the flood frequency at any station along
the study reach from Bangsai to the river mouth at Fort Chula
using theod frequencies in the Chao Phraya River have been studied
by means of a coincident flood frequen total probability theorem. The frequency and duration
relations of the upstream and downstream water levels are used as
the boundary conditions. The Single Reach with Loop Model is
applied to calculate a relationship of maximum flood level at any
station as a function of the Bangsai flood peak level and the
tides at Fort Chula. The calibration is made by adjusting the
duration curve to allow it to represent very large flood events.
Good agreement between the computed flood-stage frequency curves
and the observed one are obtained.
After calibration, the model is applied to determine the
effects of a flood control diversion channel which diverts flood
discharge at Pak Kret on the we s t bank of the Chao Phraya River.
This measure is found to reduce the flood level frequency in the
upper reach efficiently. For the lower reach , it is found not
capable enough to reduce the flood level frequency effectively . |
