Consider a farm irrigation ditch in a loam soil having the following dimensions: bottom width= 0.6 m, total depth, 0.5 m, side slopes= 1.5 horizontal to 1 vertical, and depth of water= 0.4 m. If the bottom of the ditch has a uniform slope of 2 m/km, and if the bottom & sides are kept smooth and free from weeds, what will be the mean velocity(m/s) of flow and discharge in m^3/s? Use n = 0.02. Find the shear stress at the watersurface, at half flow depth, and the canal bottom in N/m2 (or Pa). What is the shear velocity in m/sec?
If there is a layer of sand (lower layer) under artesian pressure (causes upward flow), calculate the excavation height H so that a negative effective stress is not generated at point A and therefore the heaving of the soil at that point. Use a unit weight of water w of 62.43 lb/ft3. Note: In this example we make a similarity with the permeameter with upward flow, therefore, H1=0 since from the bottom of the excavation (Na) upwards it remains dry (pumping is done), H2= 20ft-H, h=12ft-H2.
