3. Design a vertical drop structure in a lined canal carrying a
discharge to lower the canal bed by 2m. The canal sections in
the reaches U/S and D/S of structure are the same and the
details are given below:
-discharge = 5m³/s,
-bed width = 2.4m,
-Longitudinal slope = 17.7cm/km,
-Side slope = 1.5H:1V, and
-Manning's coefficient(n) = 0.015.
U/S and D/S depth of flow are the same.
Also design this drop structure as a USBR impact block type
basin. Compare the results of the two designs.
