The curve number (CN) method for estimating direct runoff response
from rainstorms was developed to fill a technological niche in the
1950s. Since then, use of the CN method has extended to other
applications, and user experience and analysis have redefined
numerous features of the original technology. In ""Curve Number
Hydrology: State of the Practice"", an ASCE/EWRI Task Committee
investigates the origin, development, role, application, and
current status of the CN method. Topics in this report include: an
introduction to curve number hydrology; the curve number method;
findings and developments; structure of the basic equation; soil
moisture modeling; calibration methods; current usage and
professional practice; and recommendations. One of the Committee's
recommendations is assigning a keeper to serve as the central
source for responsible information and updates. An appendix
provides solutions to the curve number equation. This publication
will be valuable to water and environmental engineers involved in
hydrology, especially the analysis of rainwater runoff problems.
