Inland Water Rescue and Emergencies Flashcards
Marks the area where the current splits direction of flow
Boil line
Formed when two separate flows meet
Confluence wave
Water being pushed through a narrowing gap causes the level of water to rise up forming a chute or a tongue and this is were a rescuer should swim and/or bring a boat
Downstream V
A reversal of water flow from downstream to upstream
Eddy
Using the force of the water to assist movement at a 45 degree angle
Ferry angle
Anyone within ____ feet of the water’s edge must wear a personal flotation device (PFD)
10
Where water tends to be moving slower
Inside bend
The operational zone greater than 10 feet from the water/ice
Cold
Where water meets an object and pushes water above water line
Pillow
The left side or river bank looking downstream
River left
The right side or river bank looking downstream
River right
The swimmer is positioned on their back with feet at the surface pointing downstream
Safe Swimming position
Object or structure that allows water to pass through but not a rescuer
Strainer
