THIS MONTH’S FEATURED FREE VIDEO - One of our Most Popular Civil Videos! - Water Res/Env NCEES Problem 510

On our website, we highlight our alternative (and we think better) solutions to selected problems in the NCEES Practice Exam in short videos created by our instructors. The selected problems are those that participants in our reviews have found problematic or confusing.

Problem 510 is a PM Exam problem found in the NCEES PE Civil: Water Resources and Environmental Practice Exam — but don’t be afraid to try it if you are just taking the AM portion as it’s a great problem to practice open channel flow computations!

This problem involves a channel and overbank area which need to convey a given design flood. The unknown in this problem is the width of the overbank needed such that the depth in the channel does not exceed a certain value. There are two given Manning’s n values for the channel and overbank area.

DTC HINT: Separate the main channel and overbank areas into two rectangular cross-sections, and be careful when you compute the wetted perimeter, including only the parts of the channel and overbank that are wetted.
