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.

Q: Water is flowing through an inclined aquifer (a=15°) as shown in the following figure. The depth of aquifer is H₁-3m. Two observation wells are constructed at 55m apart (S-55m) to reach the top of the aquifer. It is found that the head difference between the points, observation wells were constructed, is h=3m.

Water flows in a rectangular channel of width, w. In some cases, the water may suddenly increase in elevation as shown in the figure (from h1 to h2) through a highly disturbed region called a hydraulic jump. Assume the velocity is uniform at stations 1 and 2, and assume the pressures are distributed hydrostatically. (a) Using the conservation of mass and momentum, find the equation (cubic) for the downstream depth, h2, in terms of h1, V1, and g. (b) Using the Bernoulli equation and whatever other necessary equation(s), find the equation (cubic) for the downstream depth, h2, in terms of h1, V1, and g. In light of (a) and (b) above, does your answer to this part make sense? Explain.(c) For h1 = 1 m and V1 = 7:6 m/s, find the downstream height, h2, using whichever of the above approaches is the most correct. (Note that there are two valid solutions - explain.)
