Total Storm Runoff given W Index Solution

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

FIRST Step Consider the formula

R = P - I a - (W \cdot t e)

Next Step Substitute values of Variables

∴

R = 118cm - 6cm - (16cm \cdot 4h)

Next Step Prepare to Evaluate

∴

R = 118 - 6 - (16 \cdot 4)

Next Step Evaluate

∴

R = 0.48m

LAST Step Convert to Output's Unit

∴

R = 48cm

Other formulas in W Index category

Go W-Index

W = \frac{P - R - I a}{t e}

Go Total Storm Precipitation when W Index

P = (W \cdot t e) + R + I a

Go Initial Losses given W-Index

I a = P - R - (W \cdot t e)

Go Duration of Rainfall Excess given W Index

t e = \frac{P - R - I a}{W}

How to Evaluate Total Storm Runoff given W Index?

Total Storm Runoff given W Index evaluator uses Total Storm Runoff = Total Storm Precipitation-Depression and Interception Losses-(W-Index*Duration of Rainfall Excess) to evaluate the Total Storm Runoff, The Total Storm Runoff given W Index formula is defined as the flow of water occurring on the ground surface when excess rainwater, stormwater, meltwater, or other sources, can no longer sufficiently rapidly infiltrate into the soil. Total Storm Runoff is denoted by R symbol.

How to evaluate Total Storm Runoff given W Index using this online evaluator? To use this online evaluator for Total Storm Runoff given W Index, enter Total Storm Precipitation (P), Depression and Interception Losses (I_a), W-Index (W) & Duration of Rainfall Excess (t_e) and hit the calculate button.

FAQs on Total Storm Runoff given W Index
