Runoff given W-Index Solution

STEP 0: Pre-Calculation Summary
Formula Used
Runoff Depth = Rainfall Depth-(W-Index*Rainfall Duration)
R = Pcm-(W*tr)
This formula uses 4 Variables
Variables Used
Runoff Depth - (Measured in Millimeter) - Runoff Depth refers to the vertical height of water from precipitation or irrigation that flows over land surfaces into water bodies, typically measured in centimeters (cm).
Rainfall Depth - (Measured in Millimeter) - Rainfall Depth refers to the vertical height of rainwater accumulated over a surface during a specific period, typically measured in millimeters (mm) or inches.
W-Index - (Measured in Meter per Second) - W-Index refers to the uniform rate of infiltration during a rainstorm after initial infiltration capacity has decreased, typically measured in cm/h.
Rainfall Duration - (Measured in Second) - Rainfall duration refers to the length of time over which a rainfall event occurs, typically measured in hours or minutes, affecting runoff and infiltration.
STEP 1: Convert Input(s) to Base Unit
Rainfall Depth: 12 Centimeter --> 120 Millimeter (Check conversion ​here)
W-Index: 1.714 Centimeter per Hour --> 4.76111111111111E-06 Meter per Second (Check conversion ​here)
Rainfall Duration: 3.5 Hour --> 12600 Second (Check conversion ​here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
R = Pcm-(W*tr) --> 120-(4.76111111111111E-06*12600)
Evaluating ... ...
R = 119.94001
STEP 3: Convert Result to Output's Unit
0.11994001 Meter -->11.994001 Centimeter (Check conversion ​here)
FINAL ANSWER
11.994001 11.994 Centimeter <-- Runoff Depth
(Calculation completed in 00.020 seconds)

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.

How to Calculate Runoff given W-Index?

Runoff given W-Index calculator uses Runoff Depth = Rainfall Depth-(W-Index*Rainfall Duration) to calculate the Runoff Depth, The Runoff given W-Index is defined as excess liquid flows across surface of land and into nearby creeks, streams, or ponds typically measured in cm. Runoff Depth is denoted by R symbol.

How to calculate Runoff given W-Index using this online calculator? To use this online calculator for Runoff given W-Index, enter Rainfall Depth (Pcm), W-Index (W) & Rainfall Duration (tr) and hit the calculate button. Here is how the Runoff given W-Index calculation can be explained with given input values -> 999.4001 = rainfall_in_cm-(4.76111111111111E-06*12600).

FAQ

What is Runoff given W-Index?
The Runoff given W-Index is defined as excess liquid flows across surface of land and into nearby creeks, streams, or ponds typically measured in cm and is represented as R = Pcm-(W*tr) or Runoff Depth = Rainfall Depth-(W-Index*Rainfall Duration). Rainfall Depth refers to the vertical height of rainwater accumulated over a surface during a specific period, typically measured in millimeters (mm) or inches, W-Index refers to the uniform rate of infiltration during a rainstorm after initial infiltration capacity has decreased, typically measured in cm/h & Rainfall duration refers to the length of time over which a rainfall event occurs, typically measured in hours or minutes, affecting runoff and infiltration.
