Flow over Weirs and Hydraulic Jump
Groups of approximately four students test two or three different types of weir in the laboratory flume and determine a relationship between the head upstream of the weir and the discharge flowing over it, and to measure and comment on the properties of a hydraulic jump. One two-hour period is allocated to each group for the lab work. An individual report is required from each student, though it is expected that results and graphs are shared amongst group members. Discussions must be individual. A risk assessment is required for the laboratory.

Verbal Feedback on Tutorials on student&ęs request.
Laboratory Report returned after all students have completed it, at the end of the course. Degree Examination
