Catchment Area given Peak Rate of Runoff and Rainfall Intensity Solution

STEP 0: Pre-Calculation Summary

Formula Used

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

Variables Used

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.
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.
Runoff Coefficient - Runoff Coefficient is a dimensionless coefficient relating the amount of runoff to the amount of precipitation received.
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.

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
Runoff Coefficient: 0.5 --> No Conversion Required
Critical Rainfall Intensity: 2.01 Centimeter per Hour --> 2.01 Centimeter per Hour No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

A_c = (36*Q_R)/(C_r*P_c) --> (36*4166.67)/(0.5*2.01)

Evaluating ... ...

A_c = 149253.850746269

STEP 3: Convert Result to Output's Unit

149253.850746269 Square Meter -->14.9253850746269 Hectare (Check conversion here)

FINAL ANSWER

14.9253850746269 ≈ 14.92539 Hectare <-- Area of Catchment
