– Quantified by calculating water speed and
multiplying by approximate square footage of
river channel
– Or measure force when applied to person or
object
• Lack of planning, underestimation of
water’s power in relation to flooding
10
Swiftwater Current Categories
(1 of 8)

Swiftwater Current Categories
(4 of 8)
• Hydraulic flow:
– Vertical flow that occurs perpendicular to
laminar flow, creates circular current flowing
upstream toward obstruction

– Vertical exaggeration of normal horizontal
eddy line, usually in high-water

Phases of a Flood
•
•
•
•
Phase one: pre-flood phase
Phase two: emergency phase
Phase three: stabilization phase
Phase four: recovery phase
10
Hazard Mitigation
• Elimination or reduction possible for many
water hazards, like contaminants
• Reduction of current flow in damcontrolled rivers
• Limitation or denial of access to nonrescue personnel
– Note: mitigation may not be possible for largescale events
10
Nonentry Rescue Possible in
Some Situations
• Assisting victim has been able to selfrescue and is onshore or at edge of calm
body of water.
• Throwing victim buoyant object like Type
IV PFD, boat cushion, anything that floats
• Awareness-level responders should not
enter water to attempt rescue under any
circumstances.
