A. directly proportional to time and inversely proportional to drainage path
B. directly proportional to time and inversely proportional to square of drainage path
C. directly proportional to drainage path and inversely proportional to time
D. directly proportional to square of drainage path and inversely proportional to time
If pore water pressure increases total stress also increases.... But effective stress decreases.... If water table rises upto the ground soil is saturated then we use saturated unit weight ... Then total stress also increases
