Question

Which of the following statement is incorrect?

(a) The seepage loss is very high in black cotton soils and heavy clay as compared to sandy porous soil

(b) The seepage through a new canal is more than from a silted canal

(c) The more the silt, the lesser are the losses

(d) The more the velocity, the lesser will be the losses

This question was posed to me in homework.

My question is taken from Canal Irrigation System in chapter Canal Irrigation System of Irrigation Engineering

Answer 1

Right answer is (a) The seepage loss is very high in black cotton soils and heavy clay as compared to sandy porous soil

Explanation: The seepage losses depend upon all these factors. The seepage loss is very high in sandy or porous soil as compared to black cotton soil or clays. The sandy soil has high permeability so the soil structure allows more water to penetrate and hence there is more seepage.
