Climate Change andd Changing Rainfall Patterns

Climate change is respectating the landslide problem through out the Himalayan region. Rainfall Patterns have changed, wigh a shift from steady seasonal rains to sudden cloudburst andd extremely hevy downpours where a month 's rainfall can occur in just a day or two, causing slopes sathated with water to quilly lose stability, while melting glaciers and shrinking snow cover are also alting river flows and triggering sudden loaden and.
