The soil is A thick sandstone formatio lies below the soil. . • The depth to the water table is 5.5 m (18 ft). The silt has a capillary fringe 1.5 m (5 ft) thick. Based on this information, show the subdivisions of this cross section relative to the subdivisions of sub- surface water. Draw an appropriate hydrostatic pres- sure diagram for the cross section in keeping with Figure 13.2. 3. a. If an artesian aquifer is intercepted by a well drilled 36.6 m (120 ft) deep and the water rises in a stand- pipe to a height of 3 m (10 ft) above the ground surface, how many meters (feet) of artesian pres- sure exist for this well? b. What type of well is it? c. What was the pressure in kg/m² (psf and psi) for the water in the aquifer before entering the well? . d. If the piezometric pressure in the aquifer is reduced 4.6 m (15 ft) for every 1.6 km (1 mi) of horizontal distance, what is the hydraulic gradient for the aquifer? e. If the hydraulic conductivity of the sandstone is 4.7 m/day (15.3 ft/day), what is the average velocity of flow through the sandstone?
