Figure 5.8: Curve Number Gradient Calculation
The elasticity of the lag time to the curve number, -31.7/9.0, is –3.52. These results show that a 1% increase in CN will result in a 3.52% decrease in lag time.

Table 5.10 summarizes the results from the lag time elasticity study. Results show that the only elastic parameter is curve number. Both the longest flow path and slope are inelastic parameters.
