Area of a river where the current becomes very fast and the water moves quickly around obstacles in the river such as rocks.
An extremely fast-moving part of a river, caused by a steep descent in the riverbed.
very fast-moving river water, sometimes caused by an increase in water flow because of seasonal or weather conditions. A great example of the power of water
An area of a river, stream, or course where the current is very rapid and flows around and over various obstacles.
an area of high velocity, turbulent water often with exposed boulders or rock.
Portions of a stream with accelerated current where it descends rapidly without a break in the slope of the bed sufficient to form a waterfall.
A turbulent and swift-flowing section of a river. ( rapides)
Where boulders or rocks create turbulent water by breaking the smooth river flow.
A section of river with fast current and large rocks.
A fast, turbulent stretch of whitewater normally accompanied by rocks and a steep gradient.
Rapids are parts of a river that are shallow, rocky, and have strong currents.
Part of a river with fast-moving, shallow water . The rocks and roughness of the water make it dangerous or impassible for all kinds of water transportation. Canoes are usually carried past rapids on land.
A series of waves and turbulence.
A reach of stream that is characterized by small falls and turbulent high velocity water.
A stretch of stream where water flows quickly over boulders and small rocks. Often called white water.
Section of a river where the current speeds up and flows turbulently over and around boulders, ledges, shallows, drop-offs, and so on; whitewater.
A section of the stream where the current is above normal and rocks and debris create turbulence known as "whitewater."
Waves, whitewater, haystacks, and similar contortions of water in a fast and turbulent stretch of river.
Swift turbulent flow in a rough steep reach.
fast-flowing section of a stream, often shallow and with exposed rock or boulders (riffle, ripple).
A series of waves and turbulences.
Fast-moving water that flows around rocks and boulders in rivers; classified from I to VI according to degree of difficulty navigating.
A reach of a stream in which water becomes particularly turbulent; as a consequence, waves develop on the surface of the stream.
The section of a stream where water flows fast over hard rocks.
