A concrete culvert is to be constructed in a bed of sand (e = 0.65) for drainage purposes. The crown of the culvert will be located 3.5 m below ground surface. Currently, the groundwater level is at ground surface. But, after installation of the culvert, the groundwater level is expected to drop to 2 m below ground surface. Calculate the change in effective stress on the roof of the culvert after installation. You can assume the sand above the groundwater level is saturated.
