Q1:

The seepage exit gradient in a soil is the ratio of

A total head to the length of seepage

B flow line to slope

C head upstream to that at downstream

D head loss to the length of the seepage

E none of these.

ANS:D - head loss to the length of the seepage

EXIT GRADIENT (I) = (Head loss(H))/(Length of seepage(L)). (I)exit = head lose/last length of seepage.
