peak | R Documentation |
Very simple estimate of peak discharge.
peak(intensity, area, c = 0.25)
intensity |
Precipitation intensity (mm/hr). |
area |
Field area (ha). |
c |
Runoff coefficient, related to slope, soil type, and land cover (0-1). Forest may be 0.05 - 0.25, while paved surfaces may be 0.95. |
Peak discharge (m^3/s).
