effective stress increases with depth but water content of soil and un-drained strength decrease with depth

effective stress and water content increase with depth but undrained strength decreases with depth

effective stress and undrained strength increase with depth but water content decreases with depth

effective stress, water content and undrained strength decrease with depth

increases as the size of particles increases

increases as the soil gradation im-proves

is rarely more than 30° for fine grained soil
