GEOL 101 Lecture Notes - Lecture 12: Suspended Load, Amazon River, Bed Load
Document Summary
River systems: a river or stream is water flowing, usually in a channel, but not always, laminar flow: straight flow lines (ex: going down flat surface, turbulent flow: crazy twists and turns (ex: water rapids, high energy) Channel shape & flow velocity: more water in contact with the channel bed, means more drag, and lower velocity, wide shallow channel: high maximum velocity in middle, semicircular channel: high maximum velocity in top-middle. Discharge: the volume of water flowing past a certain point in a given unit of time, discharge (m3/s)= cross sectional area (a=w*h) * velocity, largest river (with highest discharge): amazon river. Stream gradient: gradient: vertical drop over horizontal flowing distance, average gradient= 4km/200km= 0. 02. Suspended load because you can tell when river water is dirty and colored. Sediment deposition: meandering: stream is flowing around with curves, maximum velocity in river with curves is at the outer curve.
