Piezometers are to be placed at four separate locations in a soil deposit that serves as the foundation for a concrete spillway, including a cut-off sheet pile wall, as shown (next page). The exact locations of the piezometers are identified by the four (thick) black dots. (A) Determine the total number of flow lines, flow channels, equipotential lines, and piezometric (head) drops. (B) Determine the elevation head. pressure head, and total (piezometric) head at all four separate locations where piezometers are to be installed. NOTE 1: The labeling (or numbering) of these four points is left to your own discretion. NOTE 2: Unit weight of water-9.81 kN/m", or 62.4 lb/ft². Datum TKK 0.80m 4 012345 10 1.40m ↓ T 15 5.00m 20m

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.
