Table 2. Definition of danger levels of flood waves (h: water depth; v: flow velocity)
|Danger levels and intensity of flooding
||Dam safety regulations apply if danger levels are exceeded
|h > 2m or v·h > 2m2/sec
||People inside massive buildings, in railway coaches, in passenger cars, or on camping sites are in danger.
|2 m ≥ h > 1m or 2m2/sec ≥ v·h > 1m2/s ec
||People inside buildings, in passenger cars or on camping sites are in danger.
|1 m ≥ h > 0.5m or 1m2/sec ≥ v·h > 0.5m2/sec
||People in passenger cars and on camping sites are in danger.
|h ≤ 0.5m or v·h ≤ 0.5m2/sec
||The regulations do not apply.
