<br />3.3. Hydrologic Analysis
<br />
<br />CPC was analyzed using the TR-20 model (Ref. 1,2), The basin was divided into seven
<br />subbasins as referenced in Figure 3,1 for input into the TR-20 model. Table 3.2 shows the drainage
<br />area, CN and T c for each subbasin, The model also requires channel routing parameters to account
<br />for the movement and attenuation of the flood peak, Due to the extreme variability of the steep,
<br />upiand channels, channel travel times were determined for flow velocities near critical. I n the
<br />concrete-lined channel, supercritical flow velocities were allowed,
