GLG 112 Study Guide - Final Guide: Overbank, Bed Load, Dissolved Load
Document Summary
Where does a stream get its water: precipitation, runoff, ground water. A tributary is: flows into a larger river. Perennial flows all year because: groundwater is feeding into the stream from below. Channel: channel bed: bottom of the channel, banks: sides of the channel just above the waterline, floodplain: the flat area adjacent to a channel that is periodically flooded. Levee: slightly raised land on either side of the channel created by overbank deposits. Where is the gradient of the stream the greatest: near the headwaters (change in elevation) Velocity: the distance the water travels in a given amount of time, varies greatly from stream to stream, affects streams ability to erode, transport, and deposits. Discharge: the volume of water passing a given point on the stream bank per unit of time, smaller the stream, the faster it must move. Factors controlling discharge: climate (rain, snow, etc, tributaries, size of the drainage basin, removal of water by industry/ agriculture/ cities.
