An oil tank is to be sited on a soft alluvial deposit of clay. Below the soft clay is athick layer of stiff clay. It was decided that a circular embankment, 10 m diameter,with wick drains inserted into the soft clay would be constructed to preconsolidateit. The height of the embankment is 6 m and the unit weight of the soil comprisingthe embankment is 18 kN/m3. The following data are available: thickness of softclay = 7 m, ks = 1 × 10−10 m/s and Ch = 0.6 m2/yr. The desired degree ofconsolidation is 90% in 12 months. Determine the spacing of a square grid of thewick drains. Assume wick drain of size 100 mm × 3 mm and qw = 0.1 × 10−6 m3/s.The flow point distance is 4 m. Assume a half-closed system.
A pumping well was drilled penetrating straight into an unconfined aquifer withthe thickness of 42 m. The distance of pumping well with first extraction welland second extraction well are 20 and 180 m, respectively. Meanwhile, thedrawdown for the first extraction well is 4.5 m, and the second extraction wellis 1.5 m. The constant pumping rate has been set at 0.09 m3/s. Sketch the cross section of unconfined aquifer system and label the values. ? .
Please provide solution asap with correct solution Answer is 84 KN/m^2
4.A layer of saturated clay is 10 m thick, the lower boundary being impermeable;an embankment is to be constructed above the clay. Determine the time requiredfor 90% consolidation of the clay layer. If 300 mm diameter sand drains at 4 mcentres in a square pattern were installed in the clay, in what time would the sameoverall degree of consolidation be reached? The coefficients of consolidation inthe vertical and horizontal directions, respectively, are 9.6 and 14.0 m^2/year.
A permeability test was carried out from a well that sunk through a surfacelayer of loose sand. Figure below shows the arrangement of pumping wells, togetherwith relevant dimensions. Initially, the piezometric surface (ground water table) waslocated at a depth of 2.5m. When steady state was achieved at a pumping rate 38.5 m^3/hr, the following drawdowns were observed. Pumping well, d0 = 3.64mObservation well, d1=0.96mObservation well, d2 = 0.48m Calculate the coefficient of permeability of the sand in m/hr

Geotechnical Engineering (UPVOTE WILL BE GIVEN. PLEASE ANSWER THE QUESTION CORRECLTY. NO LONG EXPLANATION NEEDED. FOLLOW THE INSTRUCTIONS CAREFULLY.) A moist soil weighed 895 g with a volume of 425 cm3. After drying, the sample weighed 775 g. Of the dried soil, 400 g was poured into a vessel loose state. Its volume subsequently determined to be 275 cm3. That same 400 g was then vibrated and tamped to a volume of 212 cm3 with Gs = 2.71. Determine the designation of the granular soil based on its relative density. (3 decimal places - Do not round off unless it's the final answer)
The coefficient of permeability below a dam is 4m/day. The water on the upstream side is 20m higher than on the downstream side. To estimate the seepage below the dam, a flownet was graphically drawn such that the number of potential drops Nd=10 and number of flow channels Nf=4. The base of the dam is founded 1m below the ground. Between the heel and the toe of the dam, a distance of 30m, there are 8 potential drops. Evaluate the seepage flow per meter width of the dam in liters per minute. Determine the uplift pressure at the heel of the dam in kPa. Determine the uplift pressure at the toe of the dam in kPa.

A course sand sample is placed in the constant permeameter test. Water passes through the sample water with a constant head of 40cm and after 0.00167hr, 40grams of water have been collected. What is the coefficient of permeability of the sand in cm/sec if the sample is placed inside a 166cm container with a 7.89cm radius?
A groundwater pump has an unknown discharge extraction rate from a confined aquifer. The thickness is 8mand K=40m/day. To estimate its flow rate, 2 observation wells were installed. The first well is 2.5km from thepump and another well 6.9km from the first well further. The observed drawdown from original water level of150m were 12m in the 1st well and 7m in the 2nd well. If the groundwater pump has a diameter of 0.80m:Determine how far in meters from the pump its influence or no drawdown effect on water table. the answer is 60,033.1092= please provide the solution so that we can understand how they get that correct answer thank you
