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.

Hydraulics,.
Water flows down a spillway at a rate (per meter of width) of q = 5 m²/s and reaches the streambed elevation horizontally. A hydraulic jump forms due to a mild slope condition at the tail water, i.e., subcritical flow downstream. The flow velocity after the jump observed is v2 = 2.0 (m/s). Determine the water depth y₁ and velocity v₁ before the hydraulic jump and the loss of energy head (h) due to the jump?

The term alternate depths in open channel flow is used to designate the depths O at the beginning and end of a hydraulic jump. O at the beginning and end of a gradually varied flow profile. O having the same specific energy for a given discharge. O having same kinetic energy for a given discharge.

The trapezoidal channel below must maintain a discharge of Q = 20 x SN (m3/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 Dc. 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). ***SN=21
