I thought this was a a good course. I used to design stilling basins for USACE. The hydraulic jump stuff was a good review of stuff I haven't thought about for a long time. I'm now in the private sector designing storm drainage systems. With regard to the long v-notch weir equation, I think there may be a missing left parenthesis or an extra right one.

Good course. I would make a correction to test question 12. An emergency spillway will be affected if a principal becomes clogged in that it would be activated. It's beneficial to have a separate emergency spillway structure in the event of a clogged PS, so that the flood may still pass without overtopping the embankment.

excellent test questions. they forced you to learn the material and apply it. The formulas in the examples need to be checked for proper use of parenthesis and the acceleration of gravity should be consistent at 32.2 ft/sec2. Sometimes its 32.0 sometimes its 32.2.

did what it needed to do, however, could not come up with the answer to question # 8. I Calculated 5.6, and the nearest answer was 5.2, got the answer correct, since there were not in that range.

For question 16 on the test the answer needs to be revised . . .
Portions of the reviewers comments have been removed because they inaccurately discuss the correct answers to test questions.

There are multiple problems with typing of the various equations in the curse document; specifically the number of left and right facing parentheses should be equal. Also check the solution for some of Kh's from chart decimal error? Spelling on p32 , "form" not "from" ?

I realize that trying to cover this topic for 4 pdh's can be difficult but I think that you could have covered more material on spliiway design by leaving out other topics such as dam classification, rainfall, energy dissipation, and spillway inspection. I know that these topics are related but each of the above topics could be another course. Dam classification varies from state to state so using two state guidleines to cover this seems wasted. FEMA has published a manual (FEMA P-679) that is 350 pages long on energy dissipation and you cover this subject in 6 pages. In touching on these subjects, you left out important issues in spillway design such as aeration under the nappe, submerged spillways, and broad crested weirs that function as sharp crested. Using only a single coefficient for each spillway type should be expanded to cover coefficients that vary with the head on the spillway. See Hulsing for proper coefficients that relate to the head over the crest.
When a engineer performs a calculation for design, he always uses references that the checker can verify. If an engineer is performing his first spillway analysis as you suggest he could from taking this course, he needs references. You should include references in your material that they could look up and use in their design. Good references for this subject include Chow (Open Channel Flow) Brater and King (Handbook of Hydraulics), Khatsuria (Hydraulics of Spillways and Energy Dissipators) and Hulsing (Measurement of Peak Discharge at Dams by Indirect Methods).
I found an error on page 12 of your material. At the top of the page, you used a head of 1.375 ft and it should have been 1.00375. On page 18, first paragraph, the words "are provided" are used twice in a row. The chart showing L/d2 vs Froude number on page 34 is used appropriately with the figure on page 33 (USBR Type IV) but the chart should not extend lower than F = 4.5 as a steady jump will not occur below this Froude number.
Question 16, Answer b on the test says the "dam has an area greater than 1000 acre-ft". The word "an area" should be replaced with the words "a storage volume". Acre-ft is a volume of water.
Overall, I think a better information could be offered for 4 pdh's.
