Correct Answer - Option 1 : Characteristics of the soil traversed by the canal system
Concept:
The process by which a liquid leaks through a porous substance is known as the process of seeping.
According to darcy’s law,
Q = kiA where K = permeability of soil
i = hydraulic gradient
A = Area of percolation
So in seepage, the discharge depends upon the wetted area.
Location of the canal also affects the hydraulic gradient available for seepage. So location of canal also influences the seepage.
The time period for which the canal is having flow, during that time seepage loss will also occur. When there is no flow or the canal is dry, there will be no seepage loss in the canal. So frequency of canal usage is also a major factor in seepage loss.
Characteristics of the soil traversed by the canal system does not influence the seepage in canal.
