Here is how the Runoff given W-Index equation looks like.

11.994 = 12 - (1.714 \cdot 3.5)

11.994cm = 12cm - (1.714cm/h \cdot 3.5h)

11.994 = 12 - (1.714 \cdot 3.5)

Runoff given W-Index Solution

Follow our step by step solution on how to calculate Runoff given W-Index?

FIRST Step Consider the formula

R = P cm - (W \cdot t r)

Next Step Substitute values of Variables

∴

R = 12cm - (1.714cm/h \cdot 3.5h)

Next Step Convert Units

∴

R = 120mm - (4.8E-6m/s \cdot 12600s)

Next Step Prepare to Evaluate

∴

R = 120 - (4.8E-6 \cdot 12600)

Next Step Evaluate

∴

R = 0.11994001m

Next Step Convert to Output's Unit

∴

R = 11.994001cm

LAST Step Rounding Answer

∴

R = 11.994cm

Note: Value should be greater than 0.

Formulas to find Rainfall Duration

Other formulas in Infiltration Index category

Go W-Index given Duration of Rainfall

W = \frac{P cm - R}{t r}

Go Precipitation given W-Index

P cm = (W \cdot t r) + R

Go Duration of Rainfall given W-Index

t r = \frac{P cm - R}{W}

Go W-Index given Runoff Coefficient

W = I \cdot (1 - C r)

How to Evaluate Runoff given W-Index?

Runoff given W-Index evaluator uses Runoff Depth = Rainfall Depth-(W-Index*Rainfall Duration) to evaluate 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 evaluate Runoff given W-Index using this online evaluator? To use this online evaluator for Runoff given W-Index, enter Rainfall Depth (P_cm), W-Index (W) & Rainfall Duration (t_r) and hit the calculate button.

FAQs on Runoff given W-Index

What is the formula to find Runoff given W-Index?

The formula of Runoff given W-Index is expressed as Runoff Depth = Rainfall Depth-(W-Index*Rainfall Duration). Here is an example- 999.4001 = rainfall_in_cm-(4.76111111111111E-06*12600).

How to calculate Runoff given W-Index?
