Problem $2$: The initial conditions for a field site are provided below. Calculate the amount of settlement of the soft clay $($CL$)$ layer due to dewatering the site, in which the groundwater table drops $2\mathrm{.}1m($to the top of the soft clay layer$).$ Assume the following parameters: $C_c=0\mathrm{.}59,C_r=0\mathrm{.}19,e_0=1\mathrm{.}90,{}_c^{\text{'}}=75$kPa. Remember to calculate the initial and final effective stresses at the middle of the soft clay layer.
