GLG 112 Study Guide - Final Guide: Sinuosity
Document Summary
Straight stream: downward erosion, side to side (lateral erosion) Bank full: river at its capacity (channel is carrying maximum water possible. Flooding: overbank flow (discharge> carrying capacity of the channel) Stage: height of water in the river at any given time. Indicates a level of water that is likely to damage. Lag time: the differences in time between peak rainfall and peak discharge of a stream. Shape of a flood: headwaters: narrow area, high height, baselevel: wide area, low height, discharge per unit area shows shape and form of the flood and the size of the flood in the drainage basin. Cause of flooding: tsunamis snow melt (controlled by temp: precipitation (amount and distribution, volcanic eruptions, dam/ levee failure, urbanization decreases lag time. Factors controlling run off vs infiltration: local topography (steep vs flat: ground material (soil vs. bedrock, preexisting soil moisture (too dry vs too wet, vegetation fires.
