A small stream is of rectangular cross section. At a certain section it divides itself, encloses an island and then re-joins to form a single channel again. The properties of the two paths past the island are as follows: At a short distance downstream of the confluence the discharge is found to be 160 m3 /s and depth of flow of 4 m. Find the discharge in each channel and the depth of flow at the point of division. Neglect the energy loss at the division and at the confluenc

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.
