GEOG 2051 Chapter : Wednesday March 14 2012 Notes
Document Summary
Why: physical disturbance, slumps_ when land collapses into river forcing the river to meander around, tributaries- when a tributary, helical flow, hydroulics- bedload, discharge, gradient. Banks with clay with strong bank becomes more of a meander. Whereas banks with more of a sand bank becomes a braided. Types of meanders: incised (stream fills valley bottom. Like in grand canyon or colorado rivers in bottom of canyons or crevasas: when the river begins to meander it can carv out the valley entrinched. If the length of the river devided by the valley length = less than 1. 5 it would be considered straight.
