LANDSLIDES IN NILGIRIS: CAUSAL FACTORS AND REMEDIAL MEASURES
-
Description
-
Landslides in the Nilgiris region of India pose significant hazards, affecting around 15% of the area, primarily triggered by heavy rainfall. Factors contributing to these landslides include improper slope excavation, excessive loading at the slope crest, blocked drainage systems, and vegetation removal. Past instances, particularly the devastating landslides in November 2009, resulted in loss of lives and substantial infrastructure damage. The study suggests that while retaining walls are commonly used, implementing cost-effective subsurface drainage systems and slope reinforcement measures could better mitigate these risks. Ongoing research aims to enhance understanding of landslide mechanisms and develop effective, site-specific remedial strategies.
