Last two digit 30
Section factor (Z).
b) | A wide rectangular discharge channel is carrying flow 2.0 + (0.01* last two digits of your
student ID) m?/s/m. If a dam is constructed at the downstream side, this will raise the water
surface at the dam at a height of 1.5 + (0.01* last two digits of your student ID) m. If the
normal depth is 1.0 m, calculate the approximate upstream distance of influence of
gradually varied flow. Also state the type of profile.
