The site shown below is initially saturated $($water table at the ground surface$).$ Dewatering will take place, and the water table will drop $4$ meters, as shown below. Consolidation of the clay will ensue. A specimen was obtained from point A and taken to the lab for testing. The following parameters were obtained: OCR$=1\mathrm{.}5,$ compression index $=0\mathrm{.}34,$ recompression index $=0\mathrm{.}05,$ void ratio $=0\mathrm{.}8,$ pre$-$consolidation stress $=130$kPa, coefficient of consolidation $=0\mathrm{.}06\frac{m^2}{?}$ day. Determine the consolidation settlement of the clay layer $90$ days after dewatering. Show your work and circle your answer.
