Guide to Stream Hydraulics

What You'll Learn

check_circleUnderstand the key parameters of channel cross-sections, including flow depth, hydraulic depth, and hydraulic radius.
check_circleLearn how to calculate dimensionless numbers like Reynolds number and Froude number using flow data.
check_circleApply the continuity equation, Bernoulli equation, and conservation of momentum equation in stream hydraulics calculations.
check_circlePerform hydraulic calculations for uniform flow, normal depth determination, and Manning’s roughness coefficient.

About This Course

This course covers several topics related to and useful for stream hydraulics calculations, including: channel cross-section parameters; the Froude number and Reynolds number; the continuity, energy, and momentum equations; hydraulic computations for uniform flow, normal depth, and roughness coefficient determination; water surface profile calculation; weir flow; hydraulic jumps; and channel routing.

In this course, you need to review the material in the NRCS National Engineering Handbook, Part 654 Stream Restoration Design, Chapter 6 Stream Hydraulics, available at: https://directives.sc.egov.usda.gov/OpenNonWebContent.aspx?content=17782.wba

Once you complete your course review, you need to take a multiple-choice quiz consisting of fifteen (15) questions to earn 3 PDH credits. The quiz will be based on the entire document.

Topics:At the conclusion of this course, the student will:

  • Be familiar with the channel cross-section parameters: flow depth, hydraulic depth, hydraulic radius
  • Be familiar with and, able to calculate if given adequate flow information, the dimensionless numbers, Reynolds number and Froude number
  • Be familiar with the continuity equation, Bernoulli equation, and conservation of momentum equation, and their use in stream hydraulics calculations
  • Be able to make hydraulic calculations for uniform flow
  • Be able to calculate normal depth for uniform flow
  • Be able to determine a value for Manning’s n value if given suitable channel information
  • Be able to make water surface profile calculations as illustrated in the course document
  • Be familiar with weirs for flow measurement
  • Be able to make hydraulic jump calculations
  • Be familiar with channel routing procedures

Intended Audience:This course is intended for Hydraulic, Water Resources, Geotechnical, Civil, Environmental, and other engineers whose job description requires a general knowledge of stream hydraulic principles.
