At a construction site, two piezometers have been installed. Piezometer A has a screen 8 m below ground surface and piezometer B has a screen 4 m below ground surface. The water level in piezometer A is 1 m below ground surface and the water level in piezometer B is 1.5 m below ground surface. Test pits at this site indicate that the water table is 1.55 m below ground surface. (5 marks) a) Is groundwater flowing up or down?...

Question 2 The soil profile at a level site consists of a 3-m thick layer of sandy clay, overlaying an 8-m thick layer of loose sand, overlaying stiff gravelly clays that extend to depths greater than 20 m. The water table is at a depth of 2 m and the ground water is initially hydrostatic. The total unit weight of the upper sandy clay, above or below the water table, is 18 kN/m3. The total unit weight of the loose...

The figure below shows the soil profile conditions below a 5-m deep pond. Water is seeping directly downward under steady-state conditions through the clay layer into underlying gravel. Assume the elevation datum at the top of the gravel layer and that the hydrostatic ground water table is also found in the top of the gravel and its position does not change with time or amount of flow. For these flow conditions, calculate the following: a. b. c. d. e. f....
