Problem: The given data are obtained from the hydrographic survey of a reservoir. The accompanying tabulation gives elevations of points over the area of 60m by 100m the surface area of the reservoir was divided into squares of 20m. Point A -1 is located in the northwest corner of the lot and D- 6 at the southeast corner. All elevations are in meters. Use contour interval of 0.50 m. The water surface elevation is 112.00m Points 2 3 4 6 A 113.7 113.2 113.5 112.15 112.3 112.7 В 112.2 110.6 109.3 109.9 110.7 112.8 C 112.7 110.4 109.5 109.2 110.5 112.6 D 112.55 112.6 112.4 112.4 112.8 112.9 1. Plot the data using a scale of 1cm = 5m. 2. Use pencil in plotting the squares. 3. Draw the contour lines. These contours represent the depth of water at every 0.50m interval. 4. Draw the longitudinal section of the reservoir showing the level of water at every 0.50 m interval.

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.
