Rational Formula Runoff Depth Calculator

Calculate the runoff depth using the formula:
\[ D = C \times I \times t \]

* Enter the runoff coefficient (0–1), rainfall intensity (mm/hr), and duration (hr).

Step 1: Enter Parameters

Example: 0.5

Example: 20 mm/hr

Example: 1 hr

Formula: \[ D = C \times I \times t \] where \( D \) is the runoff depth (mm), \( I \) is rainfall intensity (mm/hr), and \( t \) is duration (hr).
