An existing channel is to be enlarged to increase its capacity. The enlarged channel cross-section is shown in Fig. below. The existing channel is of concrete construction with a Manning's (n= 0.012), and it carries a maximum discharge of (3 m³/s). The new channel will also be constructed with concrete lining with a Manning's (n = 0.012). If the total discharge after enlargement is (9 m/s), find the normal depth in the channel. 1.2 m Ealarged Channel 1.2 m Existing Channel

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.
