Q1:

The critical exist gradient of seepage water in soils, increases with

A an increase in specific gravity

B a decrease in specific gravity

C a decrease in void ratio

D both (a) and (c)

E none of these.

ANS:D - both (a) and (c)

Critical exit Gradient ic = hl/l.
Head loss/Length of seepage.
Critical hydrulic gradient i=G-1/1+e,
So the answer is E, not D
