A pumping well has four monitoring wells, MW1 is 20m, MW2 is 500m, MW3 is 600m, MW4 is 700m, and the pond is 950m from the pumping well. The drawdown measured at MW1 during the pumping test conducted at a rate of 0.240m3/min:

T=0.195m2/min and S=1.32x10^-4

What drawdown is expected at the four monitoring wells after 5 years of pumping at 30 L/s?

Mix the aggregates given the results of sieve analysis test in Table 1 in appropriate proportions, show the granulometry curves of each aggregate and mixture in Figure 2, calculate the fineness modulus (FM) of the mixture.

3. Two triaxial tests are performed on a clay. At failure, the results are:

Test 1: σ₃ = 30 kPa, P = 0.45 kN, A = 0.01 m², u = 10 kPa

Test 2: σ₃ = 60 kPa, P = 0.70 kN, A = 0.01 m², u = 20 kPa

1. Find σ₁, σ₃, σ'₁, and σ'₃ at failure for both tests.
2. Draw the effective stress Mohr's circle for both tests and draw the Mohr-Coulomb failure envelope for the clay. What are f' and c' for the clay? Write the equation for the Mohr-Coulomb failure envelope.
3. Is the clay normally consolidated or over consolidated? Why?
