Critical Rainfall Intensity for Peak Rate of Runoff Solution

STEP 0: Pre-Calculation Summary

Formula Used

Critical Rainfall Intensity = (36*Peak Drainage Discharge by Rational Formula)/(Area of Catchment*Runoff Coefficient)
P_c = (36*Q_R)/(A_c*C_r)
This formula uses 4 Variables

Variables Used

Critical Rainfall Intensity - (Measured in Centimeter per Hour) - Critical Rainfall Intensity is the precipitation rate at which surface runoff initiates, leading to increased risk of flooding or other hydrological hazards.
Peak Drainage Discharge by Rational Formula - (Measured in Cubic Meter per Second) - The Peak Drainage Discharge by Rational Formula estimates stormwater runoff using parameters such as rainfall intensity, catchment area, and runoff coefficient to determine the maximum flow rate.
Area of Catchment - (Measured in Square Meter) - Area of Catchment refers to the area of land where all water flows to a single stream, river, lake or even ocean.
Runoff Coefficient - Runoff Coefficient is a dimensionless coefficient relating the amount of runoff to the amount of precipitation received.

STEP 1: Convert Input(s) to Base Unit

Peak Drainage Discharge by Rational Formula: 4166.67 Cubic Meter per Second --> 4166.67 Cubic Meter per Second No Conversion Required
Area of Catchment: 15 Hectare --> 150000 Square Meter (Check conversion here)
Runoff Coefficient: 0.5 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

P_c = (36*Q_R)/(A_c*C_r) --> (36*4166.67)/(150000*0.5)

Evaluating ... ...

P_c = 2.0000016

STEP 3: Convert Result to Output's Unit

5.55556E-06 Meter per Second -->2.0000016 Centimeter per Hour (Check conversion here)

FINAL ANSWER

2.0000016 ≈ 2.000002 Centimeter per Hour <-- Critical Rainfall Intensity
