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.

3. Water flows at a rate of 5 m3/s in a rectangular channel width of 10 m. The normal depth of flow in the channel is 5 m. If a sharp crested (suppressed) weir of height 5 m is installed across the channel, determine the new flow depth in the channel for the same flow rate. What would the flow depth be if the rectangular weir were contracted (on both sides) to a width if 7 m? What would the flow depth be if a 7 m wide Cippoletti weir is used?

(Problem 10.51) Water flows from a storage tank, over two triangular weirs, and into two irrigation channels. The head for each weir is 0.4ft and the flowrate in the channel fed by the 90-degree V-notch weir is to be twice the flowrate in the other channel. Determine the angle O for the second weir. .. (Ans: 2 = 53-degrees)
HYDRAULICS Convert all units in SI. Round off to 2 significant figures. Use Francis Formula. A rectangular channel 20 ft wide has a 3 ft depth of water flowing with a mean velocity of 2.45 ft per sec. Determine the height of standard sharp-created weir that will increase the depth in the channel of approach to 5 ft.
A triangular threshold is used to control the water depth which tends to be constant upstream of an open channel. Water flows on a V-notch weir with = 90^o and the magnitude of gravity is 9.81 m/s^2. What is the water discharge upstream of the threshold when conditions are normal with a water level of 0.24 m and during a flood with a water level of 1 m?
The head on a sharp-crested, rectangular weir was incorrectly observed to be 1.93 m. when it was actually 3.53 m. If the crest length is 4.83 meters, determine the percentage error (in percent) in the computed value of the flow rate. Use coefficient of discharge = 0.985. Round off to two decimal places.
2. Water flows over a sharp-crested triangular weir at a rate of 0.28m/s whose vertex angle 60°. Find the percentage of error in the computed value of the flow if the head measurement had been incorrectly observed as being 0.006m greater than its value. Use C = 0.58. Draw the sketch.
