The trapezoidal channel below must maintain a discharge of Q = 20 x SN (m/s). You may assume that the channel slope is negligible. Use MS Excel spreadsheet to plot the specific energy curve and determine the critical depth D. Hint: You should first set up a column of normal depth D (m) ranging from 0 to SN, and then calculate the area (A), velocity (V), energy (E) and Froude number (Fr).

Highway Drainage

Highway drainage is the process of extracting and regulating the excess surface water on the pavement by giving the desired slope. The construction of a highway drain helps to divert the water present on the surface, and sub-grade by the means of slope. Highway drainage systems are a necessary part of smooth functioning of traffic, since the highway drainage systems provide proper disposal of unwanted substances from the highways.
