## Runoff Coefficient Calculator

Calculate the runoff coefficient to estimate the amount of water runoff from a specific area.

### What is Runoff Coefficient Calculator?

The Runoff Coefficient Calculator helps in estimating the fraction of rainfall that will appear as runoff from a specific area. It is an essential tool in hydrology for managing water resources effectively.

### Example of Runoff Coefficient Calculator

**Input:** Rainfall = 100 mm, Runoff = 30 mm

**Output:** Runoff Coefficient = 0.3

**Here are some typical values of runoff coefficients for different surfaces:**

- Grassland: 0.1 - 0.3
- Forest: 0.1 - 0.25
- Agricultural land: 0.25 - 0.5
- Paved areas (asphalt): 0.7 - 0.9
- Concrete surfaces: 0.8 - 0.95

### How Runoff Coefficient Calculator Works?

To calculate the runoff coefficient, divide the amount of runoff by the amount of rainfall. The formula is:

**Runoff Coefficient (C) = Runoff (mm) / Rainfall (mm)**
