CE 372 Final Exam Questions With Complete Solutions
A hydraulic jump occurs when there is a break in a grade from a
Correct Answer Steep Slope to mild slope
A unit hydrograph has one unit of Correct Answer direct
runoff
At a critical state, specific energy is at its Correct Answer
Minimum
Difference in hydraulics and hydrology Correct Answer
Hydrology focuses on the study of water distribution and
movement in natural systems, like lakes and rivers; hydraulics
focuses on the engineering principles of fluid flow in pipes and
channels.
