Consider two strata of the same soil material that lie between two channels. The first stratum
is confined and the second one is unconfined, and the water surface elevations in the channels
are 24 and 16 m above the bottom of the unconfined aquifer. What should be the thickness of
the confined aquifer for which
1) the discharge through both strata is equal
A confined aquifer of 10-m thickness and 16.43 m/day hydraulic conductivity is fully
penetrated by a pumping well of 0.5 m radius operating at Q = 425 m3/day. Determine the
drawdown (Sw) under steady-state conditions in the pumping well and 50 m away from the
well. Take the radius of influence of the pumping as 300 m.
Use the unit load method to compute the horizontal displacement at A. Take E =29,000 ksi. Themoment of inertia of each frame member is shown in the figure. Assume that the support at D is a pinsupport, and a roller support at A. Ignore shear and axial deformations, i.e., assume that thedeformations are due to bending only.
Please show the actual steps and calculations/diagrams to solve. The last time I asked this question those were not provided.
