Runoff Volume Calculator

Runoff Volume Calculator calculator can be used to estimate the volume of runoff from a given area based on rainfall intensity and duration.

Input Parameters

Calculation Results

Calculation Formula

Runoff Volume (m³) = Area (m²) × Rainfall Intensity (mm/hour) × Duration (hours) / 1000

Where:
Area (m²): The area of the region from which runoff is being calculated.
Rainfall Intensity (mm/hour): The rate at which rain falls.
Duration (hours): The length of time the rain falls.

Result

Runoff Volume: 0 m³

Runoff Volume Calculator Calculator Usage Guide

Learn how to use the Runoff Volume Calculator calculator and its working principles

How to Use the Calculator

  1. Enter the area of the region in square meters (m²).
  2. Enter the rainfall intensity in millimeters per hour (mm/hour).
  3. Enter the duration of the rainfall in hours.
  4. Click the "Calculate" button to compute the runoff volume.
  5. The runoff volume in cubic meters (m³) will be displayed.

Working Principle

The runoff volume is calculated using the formula:

Runoff Volume (m³) = Area (m²) × Rainfall Intensity (mm/hour) × Duration (hours) / 1000

This formula estimates the volume of water that runs off an area during a specific rainfall event by multiplying the area by the rainfall intensity and duration, then converting the result from milliliters to cubic meters.

Example

If you have an area of 1000 m² and it rains at a rate of 50 mm/hour for 2 hours, the runoff volume would be:

Runoff Volume = 1000 m² × 50 mm/hour × 2 hours / 1000 = 100 m³
