This 2-hour interactive online course is the fourth of a RedVector.com series presenting the basic hydraulics of open channel flow, the field of engineering fluid mechanics encompassing free-surface discharge. This course explores water surface profiles associated with nonuniform flow, the flow state where depth changes with channel distance.

Nonuniform flow was introduced in the first course, but postponed computationally until we covered the fundamentals of uniform flow. If you are not familiar with the concept and use of specific energy, specific force and Manning's Equation, work on these basics first. This course will refer to earlier content. Subsequent RedVector.com courses will progress to more-complex profiles and then a variety of applications in both design and hydrologic analyses.

This course includes a multiple choice quiz at the end.

As mentioned above, RedVector.com does offer the first three courses in this series:
Open Channel Hydraulics I: Introduction and Energy Balance (2 hours)
Open Channel Hydraulics II: Force Balance and Critical Depth (2 hours)
Open Channel Hydraulics III: Uniform Flow (2 hours)
It is recommended that you take Part I, Part II and Part III before taking this course. If you are interested in these courses, please return to the course listing.

Course Objectives
Upon completion of this course, the student will:
  • Understand basic terminology and will have worked problems involving gradually varied flow on mild slopes
  • Have a qualitative sense of how flow profiles are shaped.
  • Better understanding of Manning's equation.
  • Learn how to compute normal and critical depths, E and Froude Number which will get you through much of the number crunching.

You’ll also quickly appreciate the efficiency of using a water surface profile computer package for design and analysis. You might have access to the U.S. Army Corps of Engineers public-domain routines HEC-2 or HEC-RAS. You might prefer another program. Computers save time and generate output that looks authoritive. After this course, you’ll be familiar with what the computer is doing. You’ll be better able to instruct the computer, relying on output not because it’s nicely formatted, but because you anticipate what it should be saying.

You’ll need no more than another cell or two in the spreadsheet you constructed in the previous RedVector.com open channel courses. If you have more computational power at hand, don’t use it before you’ve worked through the steps.
