Contracted rectangular crested weir. A contracted rectangular crested weir is one type of sharp crested weir, and is of the options that can be used to meter flow rate in an open channel. The head over the weir is measured and can be used to calculate the water flow rate over the rectangular weir (and through the open channel proach annel B Flow Weir plate Problem: A contracted rectangular sharp-crested weir 2.63 m long discharges water under a head of 87 cm. Compute the flow by using the Francis correction formula. Check by Cone formula

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.
