Water table in a canal command receives a recharge at the rate 2.5 mm/day. Sub-surface ditch drains at a spacing of 2 km are provided for the sub-surface drainage. Estimate the maximum rise of the water table at steady state. Given: hydraulic conductivity of the soil = 10 m/day, depth of the impervious layer below initial water table position = 20 m. Assume the ditches to be fully penetrating.
The flow net under a hydraulic structure has 5 flow channel with 10 equipotential drops. If the permeability of the bed material is 1.5 *10^-4 m/sec, find the quantity of seepage per meter width of the structure in m ^ 2 /sec under 3m head.
