Management of Sediment-Related Risks

Flood Management Tool Series, Technical Document No. 12 ¦ 2011

Sediment-related disasters, which are caused by debris flows, slope failures and landslides, have different characteristics from water-related disasters. That is, disasters sites, timing of occurence, and hazard levels are difficult to predict accurately. This Tool explains practical approaches of identifying debris flows and landslides areas and introduces good practices of mitigation measures to minimize human loss. For example, disaster prevention maps containing hazard areas, sage refuges and evacuation routes are as essential and effective means as flood hazard maps.
