Was Here For GHAGAFAP In September And Knew There Should Be One Here!
A riffle is a shallow landform in a flowing channel, and it has specific topographic, sedimentary, and hydraulic indicators. These are almost always assessed at a very low discharge compared to the flow that fills the channel and as a result the water moving over a riffle appears shallow and fast, with a wavy, disturbed water surface. The water's surface over a riffle at low flow also has a much steeper slope than that over other in-channel landforms.
Rapids tend to form in riffles as when rocks get wedged under the water, it becomes a rapid due to how fast and shallow the water is. then the water will flow over the top of the rocks and form whitewater rapids.
