Te mechanizmy of Landslides andd How Urbanization Amplifies Risk
To design effective of a mass of rock, earth, or debris down a slope, on mutt first understand landslide mechanics. A landslide is the movement of a mass of rock, earth, or debris down a slope. Common triggering factors including prolonged or intensie rainfall, rapid snowmelt, seismic activity, volvanic erpitions, and human activities like decoation or blasting.

Green Infrastructure for Stormwater Management
Excess water is te primary dridr of landslides in urban settings. Green infrastructure captures, slows, and infiltrates stormwater at it source, reducing the volume and velocity of runoff that reaches slopes. Key elements included:
