A stream has the following cross-sectional data: Station Distance up the Stream Elevation of the Stream Bed (m) Cross-section 1 50 m 100 Trapezoid, B = 15 m, m = 1.50 2 52 m 101 Trapezoid, B = 14 m, m = 1.50 3 54 m 102 Trapezoid, B = 14 m, m = 1.25 4 56 m 103 Trapezoid, B = 13 m, m = 1.25 For a discharge of 150 m3 /s, the depth of flow at downstream Section 1 is 5.10 m. Assume n = 0.025. Using the standard-step method, compute the water-surface elevations at Sections 2, 3 and 4. (Assume gradual transition).

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.
