Curve Number Hydrology: State of the Practice

摘要

The Curve Number (CN) method is a simple and popular model used in many hydrologic applications. Since its inception in 1950s by the U.S.D.A Soil Conservation Service (SCS), today known as the Natural Resources Conservation Service (NRCS), the original method and its modifications have been widely applied in the U.S. and other countries. This book aims to compile a broad range of knowledge about the science, applicability, and limitations of the CN method, describes model limitations, and makes recommendations for its appropriate application.rnThe book consists of four chapters. History and the need for developing the original CN method to meet the mandate of the Small Watershed and Flood Control Act of 1954 (PL-566) is presented in Chapter 1.
