Transcript of White water rapids

White water rapids
This is an example of a man made rapid.
How they are created.
Four factors, separately or in combination, can create rapids: gradient, constriction, obstruction and flow rate. Gradient, constriction and obstruction are streambed topography factors and are relatively consistent. Flow rate is dependent upon both seasonal variation in precipitation and snowmelt and upon release rates of upstream dams
What fish are in white water.
The fish that are in the rapids are salmon and this are the risks they take.
What boats do you need?
You need to have a blow up boat. It is a material blow up boat to make sure when you hit rocks the boat doesn't burst.
This is one of the biggest waterfalls in USA.
What is the fun of white water

Fast white water rapids!
