i. Proper maintenance of hill side drain ii. Damaged gabion wall can be repaired or modified after removing the slide materials.
i. Adverse condition of rockmass. Slope forming material is composed of loose fragments of parent rockmass intermixed with soil ii. Flowing hydrological condition iii. Drainage dissections on the affected slope which is in flowing condition.
