5.What is the ideal slope range for the downstream glacis in a strong hydraulic jump with maximum energy to ensure optimal energy dissipation?
6.What is the term used to describe the gradual erosion and lowering of the riverbed downstream of a constructed weir?
7.Using Lacey's formula for the wetted perimeter, what is the value of the constant P in the equation P = ______ (Q)^{1/2} for determining the waterway of a weir?
8.What is the name of the water reservoir constructed downstream of a hydraulic structure to absorb the energy of falling water by forming a water cushion?
