Catchment Factor given Run-off in Inches by Lacey's Formula Solution

STEP 0: Pre-Calculation Summary

Formula Used

Catchment Factor = (-120*Monsoon Duration Factor*Runoff Depth in Inches)/(Runoff Depth in Inches*Rainfall Depth-Rainfall Depth*Rainfall Depth)
S = (-120*F_m*R)/(R*P_RD-P_RD*P_RD)
This formula uses 4 Variables

Variables Used

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

STEP 1: Convert Input(s) to Base Unit

Monsoon Duration Factor: 0.0027 --> No Conversion Required
Runoff Depth in Inches: 4 Inch --> 0.101600000000406 Meter (Check conversion here)
Rainfall Depth: 5 Inch --> 0.127000000000508 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

S = (-120*F_m*R)/(R*P_RD-P_RD*P_RD) --> (-120*0.0027*0.101600000000406)/(0.101600000000406*0.127000000000508-0.127000000000508*0.127000000000508)

Evaluating ... ...

S = 10.2047244094078

STEP 3: Convert Result to Output's Unit

10.2047244094078 --> No Conversion Required

FINAL ANSWER

10.2047244094078 ≈ 10.20472 <-- Catchment Factor

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. Runoff can come from both natural processes and human activity. The most familiar type of natural runoff is snowmelt.
