4. A canal is cut into a soil as shown in the figure. Assume flow takes laterally and vertically
through the sides of the canal and vertically below the canal. The values of k= k; =k; in each
layer are given.
10 m
k= 2.3 x 10 cm/s
3.0 m
1.5 m T
k = 5,2 × 10* cms
2.0 m
k = 2x 10 cm/s
12 m
k= 0.3 x 10 cm/s
3.0 m
k = 0.8 - 10'cm/s
a. What is the equivalent permeability in the horizontal direction through the sides of
the canal in cm/day?
b. What is the equivalent permeability in the vertical directions through the sides of the
canal in cm/day?
c. Determine the equivalent permeability in the vertical directions below the bottom of
the canal in cm/day?
