ESS102H1 Chapter Notes - Chapter 6: Bed Load, Water Cycle, Turbulence
Document Summary
Important that hydrologic cycle stays balanced; since the total water vapour in the atmosphere remains about the same, average annual precipitation over. If we were to examine the longitudinal profile (side view) of a major stream we would notice that the slope or gradient of its channel is far from constant (it is concave up) Changes from upstream to downstream: a stream can maintain higher velocity near its mouth, where it has a lower gradient, than upstream because of the greater discharge, larger channel, and smoother bed. [glg text notes chapter 6] 4: the competence of a stream indicates the max particle size that a stream can transport; stream"s velocity determines this, the greatest erosion and transportation of sediments is during floods. Main channel can divide into several smaller ones called distributaries. Factors influencing the storage and movement of groundwater.
