River Stuff
This is what rivers carry.
What is, weathered sediment?
This is when water flows in thin sheets at the bottom of a river.
What is, laminar flow?
This is the part of a curve in a river where velocity is least.
What is, the inside?
This is when sediments of the bedload bounce from place to place.
What is, saltation?
This is where meandering channels occur.
These are the two features that control rivers.
What are, gravity and friction?
This is when eddy currents circulate in random directions, but net flow is downhill.
What is, turbulent flow?
These are the features that affect the channel of stream at the outside of a curve.
What are, weathering and erosion?
This is when sediments of the bedload roll or are pushed along by the current.
What is, traction?
This is what causes a meandering channel to become braided.
What is, increased gradient?
This is the shape of the valley that rivers create.
What are, V-shaped Valleys?
These are the parts of the stream where velocity is greatest.
What are, the top and middle?
This is the feature that affects the channel of stream at the inside of a curve.
What is, deposition?
This is when straight segments are joined by slight bends; and bars of sediment develop from side to side because max flow/velocity and deepest water move from side to side of the channel.
What is, a straight channel?
A meandering channel must first start with this.
What is, a disturbance?
This is the view from which one can see the V-shape valley.
What is, a cross-section view?
This is why velocity is lower at the bottom and sides of a stream.
What is, friction between water and material of the channel?
What is a suspended load?
This is when several channels divide, join, divide, re-join; and bed material separates channels at normal rate of flow, but becomes submerged at high flow rate.
What is, a braided channel?
This is a lake that can form when a meander gets cut off from the original river.
What is an oxbow?
This is the number of types of flow of water in a river.
What is, 2?
This is the part of a curve in a river where velocity is greatest.
What is, the outside?
These are particles that move on or near the bottom of stream/river.
This is a channel of symmetrical sinuosity and regular intervals of back-and forth bends; can result in an oxbow lake
What is a meandering channel?
As velocity of the stream increases, so does this feature of sediments moved by the stream.
What is, grain size?
