Analysis
Runoff Coefficients
1. Long Term Runoff Coefficient: 2.55
Highest Monthly Coefficient: 0.432 Month: March
Lowest Monthly Coefficient: 0.038 Month: September
2. Flood Year Runoff Coefficient: 2.60
Highest Monthly Coefficient: 0.675 Month: July
Lowest Monthly Coefficient: 0.033 Month: October
3. Drought Year Runoff Coefficient: 0.390
Highest Monthly Coefficient: 0.143 Month: March
Lowest Monthly Coefficient: 0.002 Month: September
4. 30-day Flood Runoff Coefficient:
Different years produce different runoff coefficients within the same
drainage basin because precipitation and evaporation values vary from
year to year. If a year is experiencing heavy precipitation then the soil
moisture will be high, this will increase the runoff within the basin. On
the other hand, when there is a drought year the infiltration rates will be
higher. This will lead to a lower runoff coefficient. This also applies for
different times within one year. Each year experience wet and dry
seasons which will affect the runoff coefficients within the basin.

Discharge: 7,986,328 a.f. 117.35 in.
Residual: -7,536,226 a.f. -110.74 in.
The residual based upon Penman PET has a value of -128.97 inches. This
value explains how our basin would need an additional 128.97 inches to have a
net value of zero. Under the Thornthwaite PET our basin would only need an
additional 110.74 inches. The Thornthwaite value is less because it has a lower
PET value.
