The figure below shows the soil profile conditions below a 5-m deep pond. Water is seeping directly downward under steady-state conditions through the clay layer into underlying gravel. Assume the elevation datum at the top of the gravel layer and that the hydrostatic ground water table is also found in the top of the gravel and its position does not change with time or amount of flow. For these flow conditions, calculate the following: a. b. c. d. e. f....

A constant-head permeameter has a diameter of 2.5 cm. A 5.0 cm soil sample with the same cross-sectional area is place in the permeameter. When a head difference of 5 cm is applied between the inlet and outlet ports, the permeameter discharges 50 cm3 of water in 90 s. (a) Calculate the hydraulic conductivity of the soil in m/s and in ft/day. (b) What is the intrinsic permeability of the soil at 20 ◦C? (c) What would be the soil’s...

Contaminant sorption and flow in subsurface environment (12 points) An aquifer is contaminated due to a recent spill of a certain industrial solvent. The aquifer has a hydraulic head difference of 0.01 m as measured by two piezometers about 2 m apart along the direction of groundwater flow. The aquifer has a porosity of 0.3, organic carbon (foc) of 1.7%, soil particle density of 2.6 g/cm, and hydraulic conductivity (K) of 2.5 x 10-3 cm/sec The solvent has a log...

3. The flow net shown below illustrates flow conditions beneath a concrete dam featuring an upstream "clay blanket" (an impermeable clay layer) and a downstream "cutoff wall", both of which serve to lengthen the flow path. The coefficient of permeability, k, of the permeable strata is 8 x 10 cm/s. a. Calculate the flow rate, q, per day beneath the dam (per m of dam out-of-plane). b. Calculate the total head, elevation head, pressure head, and pore water pressure at...
