1. After a heavy downpour, the depth of water over the weir was 4m. If the total discharge through the weir was 1,000,000 m3, how long did the flow over the weir last? a. If a rectangular weir is used having a length of 200m. b. If a trapezoidal weir is used with its sides making an angle of 75°57'49" with the horizontal and the weir has a bottom length of 200m. c. If a rectangular contracted weir (both sides) is used with a length of 200m. Ans: a: 11.32 minutes, b: 11.21 minutes, c: 11.37minutes

Q: 2. Determine the discharge of the weir having a head of 1.2 m in L/s a) If a 90° triangular weir is…

A:

Q: Determine the discharge over a standard contracted weir when the upstream water depth is 2.1 m. The…

A: Step 1

Q: Design a weir according to the following data: Channel width = 6 m. Flow discharge = 5 m³/s.…

A: Channel width (b) = 6 m Discharge (Q) = 5 m3/sCd = 0.65

Q: 1. After a heavy downpour the depth of water over the weir is 4 m. If the total discharge through…

A: H = 4 mQ = 1000000 m3

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.
