Mudslides or mudflows, are a special case of landslides, in which heavy rainfall causes loose soil on steep terrain to collapse and slide downwards.

Rockfall Hazard Mitigation 
Rockfall is common in areas of the world with steep rock slopes and cliffs. 
Commonly, these are mountainous or plateau areas, whether in coastal areas or 
among isolated rock formations. Rockfall causes extraordinary amounts of monetary 

damage and death, the former mostly by impeded transportation and commerce due 
to blocked highways and waterways and the latter as direct casualties from falling 
rocks. Diverting paths and highways around rockfall areas is sometimes implemented but is not always practical. Many communities post danger signs around 
areas of high rockfall hazard. Some methods of rockfall hazard mitigation include 
catch ditches, benches, scaling and trimming, cable and mesh, shotcrete, anchors, 
bolts, dowels, and controlled blasting.
Debris-Flow Hazard Mitigation 
Due to the speed and intensity of most debris flows, they are very hard to stop 
once they have started. However, methods are available to contain and deflect debris 
flows primarily through the use of retaining walls and debris-flow basins. Other mitigation methods include modifying slopes (preventing them from being vulnerable 
to debris-flow initiation through the use of erosion control), revegetation, and the 
prevention of wildfires, which are known to intensify debris flows on steep slopes..
Landslide Dam Mitigation
Many problems arise when landslides dam waterways. Dams caused by 
landslides are a common problem in many areas of the world. Landslides can occur 
on the valley walls of streams and rivers. If enough displaced material (rock, soil,

are frequently composed of loose, unconsolidated material, they commonly are 
inherently weak and are soon overtopped and fail due to erosion. When breaching happens quickly, the backed-up water rushes down the waterway, potentially 
causing catastrophic downstream flooding.
