Stream: a body of running water confined to a channel moving downhill under the force of gravity


Transport of sediment by streams


Stream Erosion


Stream Valleys and flood plains


Channel deposits - Sand and gravel bars, cross beds. Ripples and ripple marks occur in slow and moderate streams, larger dunes occur in higher velocity streams


Channel Patterns


Discharge - volume of water per unit time past a given point


Flood frequency curves - average recurrence interval for a flood of a given size (estimated)


Longitudinal Profiles - elevation of stream versus distance from the headwaters down to the sea

Drainage patterns and deposits
