Question 12 Water is flowing downwards through a vertical sand column as shown in Figure 6. The length of the column L 160 cm, the cross-sectional area A 220 cm2, the head difference Ah 130 cm (assume this head difference is constant). The sand in the column has a hydraulic conductivity k 25 m/d and the porosity n=0.32. Determine the steady state seepage velocity of soil.

1. A soil column has a sample of medium-grained sand 15-cm in height and 25 cm2is cross-section area. With a head of 5.0 cm, a total of 100 ml of water is collected in 12 min. Find the hydraulic conductivity and flux
A 100 cm long soil column containing packed sand with a hydraulic conductivity (K) of 100 cm/day is placed vertically with the bottom open to the atmosphere. A constant head of 10 cm of water is ponded continuously at the top surface. Calculate the steady state flux Jw through the column.
2. A cylindrical sample of soil is confined in a rigid-wall permeameter and measures 10 cm in diameter and 20 cm in length. The axis of the cylindrical sample lies in a horizontal plane. They hydraulic head at the left end of the specimen is controlled by a reservoir; the water surface in the reservoir is exactly 100 cm above the horizontal axis of the cylindrical soil sample and remains at 100 cm through a system that automatically adds water...

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 бс) of 1.7%, soil particle density of 2.6 g/cm3, and hydraulic conductivity (K) of 2.5 x 103 cm/sec The solvent has a log...
3. During a springtime rain event, flow develops through both the sludge and peat layers in the soil profile below. A piezometer with its tip at the base of the peat layer indicates a water rise to 0.6 m above the fill surface (an upward flow condition). What are the new total, elevation, and pressure heads at 0.6m below the top of the sludge layer? Assume head loss occurs through both the sludge and the peat layers. 0.6 m 1...
