Abstract
Landslide is one natural hazard which causes lot of damage, different methods of
stabilization are currently practised, among them soil reinforcement with tree
roots. The roots increase the shear strength of soil by transmitting developed
shear stress to tension strength. The additional strength created by roots is
defined as the growing cohesion, which increases with vertical stress and area
occupied by the roots. In this research, an attempt was made to study the effect
of willow root on a clayey soil. Large-scale in-situ direct shear tests were carried
out on both rooted and rootless soils. The occupied root area was calculated by
counting the number and measuring the diameter of all
