Question

A pressure increase of 250 kPa is imposed across a wide region above the depicted soil profile. The clay stratum is initially under normal consolidation and has a coefficient of consolidation (cv) of 0.002 cm2/s. The groundwater level sits 3.5 meters beneath the soil surface. Determine the settlement of the clay layer, in millimeters, 40 days following the application of the pressure increase. noted that The final settlement at the end of primary consolidation is equal to 515 mm.

The owner of a small factory has installed a new well to supply process water. The well is 0.3 m in diameter and is fully screened for the entire 12 m depth of the aquifer, which is composed of coarse sand having a bulk density of 2 g/cm3, K of 0.1 cm/sec, porosity of 0.25 and organic content of 0.5%. The radius of influence of this well can be taken as 3,000 m. What is the steady state drawdown of the well, if the average water use by the factory is 360 L/min. A plume of TCE-contaminated groundwater lies 800 m from the well. How fast is the TCE plume moving towards the well? Neglect any movement that may be due to regional groundwater flow and consider only the influence of well pumping at hydraulic steady state. Please only use the equation I have provided to answer this question. Thank you
