A site 80m40m will need to be dewatered for an excavation. The water level is 1.2 meters
below the ground surface, and the excavation needs to go 10 meters below the surface. An
additional 2 meters from the excavation is required in the drawdown for the safety of boiling.
Two wells will be used in this operation in the middle of the long-sided edge. Determine the
flow (Q) in m3? day for EACH well for a steady state operation. Given the bedrock is 23m from
the ground, the hydraulic conductivity for the site is 10-4cms, and the estimated radius of
influence is 400m for this operation.
