Runoff Coefficient given Runoff Rate of Rainwater from Bridge during Rainstorm Solution

STEP 0: Pre-Calculation Summary

Formula Used

Runoff Coefficient = Peak Rate of Runoff/(1.00083*Intensity of Rainfall*Catchment Area for Rainstorm)
C_r = q_p/(1.00083*I*A_catchment)
This formula uses 4 Variables

Variables Used

Runoff Coefficient - Runoff Coefficient is a dimensionless coefficient relating the amount of runoff to the amount of precipitation received.
Peak Rate of Runoff - (Measured in Cubic Meter per Second) - Peak Rate of Runoff is the maximum rate of discharge during the period of runoff caused by a storm.
Intensity of Rainfall - (Measured in Meter per Second) - Intensity of Rainfall is the ratio of the total amount of rain (rainfall depth) falling during a given period to the duration of the period.
Catchment Area for Rainstorm - (Measured in Square Meter) - Catchment Area for Rainstorm is the total area of the catchment from where total runoff water is collected.

STEP 1: Convert Input(s) to Base Unit

Peak Rate of Runoff: 1.256 Cubic Meter per Second --> 1.256 Cubic Meter per Second No Conversion Required
Intensity of Rainfall: 16 Millimeter per Minute --> 0.000266666666666667 Meter per Second (Check conversion here)
Catchment Area for Rainstorm: 9412 Square Meter --> 9412 Square Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

C_r = q_p/(1.00083*I*A_catchment) --> 1.256/(1.00083*0.000266666666666667*9412)

Evaluating ... ...

C_r = 0.500009981090959

STEP 3: Convert Result to Output's Unit

0.500009981090959 --> No Conversion Required

FINAL ANSWER

0.500009981090959 ≈ 0.50001 <-- Runoff Coefficient
