4. A rectangular canal of length 1 km and depth 1 m is excavated for rural drinking water supply parallel to a river at a sideway distance of 0.5 km measured along the surface of a sloping ground. The difference of free water surface elevations measured from the free surface levels in the river and trench is recorded as 0.95 m. The area underlying between the river and trench is composed of a soil having an equivalent permeability of 8.59 x 10-8 m/s and void ratio of 0.85. Calculate the volume of water collected in the trench for a period of 10 days. Also calculate the number of days required for a pollutant to reach to the trench from the river. Assuming trench is perfectly dry initially and water is seeping only from the river into the trench.
