No remedial measures suggested as concrete wall with sufficient weep holes and lined hillside drainage is already constructed.
1. Extensive slope cutting for road construction 2. Pore water pressure developed in the slope forming material due to oversaturation during heavy rainfall and thereby reduces its shearing strength.
