Daily Runoff in Smaller Catchments under SCS Solution

Follow our step by step solution on how to calculate Daily Runoff in Smaller Catchments under SCS?

FIRST Step Consider the formula

Q = \frac{{(P T - 0.2 \cdot S)}^{2}}{P T + 0.8 \cdot S}

Next Step Substitute values of Variables

∴

Q = \frac{{(16m³ - 0.2 \cdot 2.5m³)}^{2}}{16m³ + 0.8 \cdot 2.5m³}

Next Step Prepare to Evaluate

∴

Q = \frac{{(16 - 0.2 \cdot 2.5)}^{2}}{16 + 0.8 \cdot 2.5}

Next Step Evaluate

∴

Q = 13.3472222222222m³

LAST Step Rounding Answer

∴

Q = 13.3472m³
