A concrete spillway, including a cut-off wall, is designed as shown (next page). Elevations of upstream and downstream water levels, taken from an undisclosed datum, are 260.3 ft. and 193.3 ft., respectively. The elevation of the base of the spillway, also taken from the same undisclosed datum, is 180.0 ft. (A) Report the total number of flow lines, flow channels, cquipotential lines, and piezometric (head) drops. (B) Compute the uplift pressure acting against the base of the spillway at its left corner (just the left corner: do NOT waste time calculating for any other intermediate point along the base). (C) Report the elevation head, pressure head, and total head at this particular point (just the left corner).

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.
