How are mudflows divided by their place of impact on the environment?

Mudflows are divided into 4 groups:
1. Low-power – small erosion, partial blockage of openings of culverts;
2. Medium-powerful – strong erosion, complete blockage of holes, damage and demolition without foundation structures;
3. Powerful – a great destructive force, the demolition of bridge farms, the destruction of the supports of bridges, stone buildings, roads;
4. Catastrophic – the destruction of entire buildings, sections of roads along with the bed and structures, the burial of structures under mudflows.
