The subsoil at the site consists of a 10 m thick
homogeneous layer of dense sand having the following
properties:
Dry unit weight = 16 kN/m3,
Gs = 2.68,
angle of friction = 35 degrees
The natural ground water table lies at 2 m below the ground surface.
Determine the change in shear strength
at 10 m depth (kPa).

An existing unlined channel is having the following dimensions:
Bottom width = 1.52 m; Side slopes = 1:1; Flow depth = 0.90meter; and
Bed-slope = 1/1667.
It is proposed to line this channel for the same discharging capacity. Find out the dimensions of the lined channel and work out the economics of the concrete lining, if following data are given:
Length of irrigation season = 150 days;
Saving in seepage loss by lining the canal = 1.5 per cent per km
Cost of water = Rs.150 /ha/m; Cost of concrete lining = Rs.16 /sq. m
Cost of reshaping and trimming canal = Rs. 4.00 per sq. m.
Life of lining = 40 years; Interest rate = 7 percent.
Annual maintenance and operational cost (rupees per km per year)
for unlined canals earth = Rs.1000; for concrete lined canals = Rs. 200
Other additional benefits = Rs. 350.00
Assume any other necessary data, if not given.
