National Engineering Handbook: Chapter 14 - Stage Discharge Relations
Natural Resources Conservation Service, 2012
In planning and evaluating aspects of watershed protection, it is necessary for U.S. Department of Agriculture (USDA) Natural Resources Conservation Service (NRCS) hydrologists and engineers to develop stage discharge curves at selected locations on natural streams.
Many hydraulics textbooks, handbooks (NRCS Nation-al Engineering Handbook (NEH) Section 5, Hydraulics, 1956), and others contain methods for developing stage discharge curves assuming nonuniform steady flow. Some of these methods are elaborate and time consuming. The type of available field data and the use to be made of these stage discharge curves should dictate the method used in developing the curves.
This chapter presents methods of developing these curves at selected points on a natural stream. This chapter demonstrates hand calculation methods. Many of these are now automated by computer programs such as HEC–RAS (2010b).
