Uniform flow hydraulic parameters
short url for this page: http://go.usa.gov/0Eo
The following Microsoft Excel spreadsheet was developed by the NRCS Water Quality and Quantity Technology Development Team, has been tested, and correctly produces the results of Manning's equation for uniform flow in a cross-section. The spreadsheet employs macros which are safe in this version at the time downloaded. The user is cautioned that proper use of the spreadsheet requires training in hydraulics.
These files require Microsoft Excel , Microsoft Word , or a zip program.
