1. Construction of drainage ditches (lined hillside drain) along the road.
2. Retaining wall may be constructed at the toe of the slope and below the road bench on sound foundation.
1. Excavation or cutting of slope 
2. Weak slope forming material developed local hydrostatic pore pressure due to incessant rainfall rendering the weak slope to lose its shear strength.
