What is Runoff Curve Number?

The Runoff curve number is an empirical parameter used in hydrology for predicting direct runoff or infiltration from rainfall excess. The curve number is based on the area's hydrologic soil group, land use, treatment and hydrologic condition.

What is Curve Number and on what factors it depends?

The Curve Number (CN) is a dimensionless parameter related to the potential maximum retention expressed in millimeters. It ranges from 0-100. A CN value of 100 represents a condition of zero potential retention and CN= 0 represents an infinitely abstracting catchment with S= ∞.
The Curve Number CN depends upon the following listed below
1. Soil Type
2. Land Use/Cover
3. Antecedent moisture condition
