Run-off in cm by Lacey's Formula Solution

STEP 0: Pre-Calculation Summary

Formula Used

Runoff Depth = Rainfall Depth in Centimeters/(1+(304.8*Monsoon Duration Factor)/(Rainfall Depth in Centimeters*Catchment Factor))
R_cm = P_cm/(1+(304.8*F_m)/(P_cm*S))
This formula uses 4 Variables

Variables Used

Runoff Depth - (Measured in Meter) - Runoff Depth at the measuring point in the receiving water results in the arithmetical mean of the values of the total runoff depth.
Rainfall Depth in Centimeters - (Measured in Meter) - Rainfall Depth in Centimeters is the total amount of rain falling over a catchment area in terms of depth.
Monsoon Duration Factor - Monsoon Duration Factor depends on the monsoon rains.
Catchment Factor - Catchment Factor are topography, shape, size, soil type, and land use (paved or roofed areas).

STEP 1: Convert Input(s) to Base Unit

Rainfall Depth in Centimeters: 10 Centimeter --> 0.1 Meter (Check conversion here)
Monsoon Duration Factor: 0.0027 --> No Conversion Required
Catchment Factor: 2 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

R_cm = P_cm/(1+(304.8*F_m)/(P_cm*S)) --> 0.1/(1+(304.8*0.0027)/(0.1*2))

Evaluating ... ...

R_cm = 0.0195511065926331

STEP 3: Convert Result to Output's Unit

0.0195511065926331 Meter -->1.95511065926331 Centimeter (Check conversion here)

FINAL ANSWER

1.95511065926331 ≈ 1.955111 Centimeter <-- Runoff Depth

What is Runoff ?

Runoff occurs when there is more water than land can absorb. The excess liquid flows across the surface of the land and into nearby creeks, streams, or ponds.
