Streams
Introduction to the hydrologic cycle
Basic Definitions:
Gradient
Base level
Discharge
Streams in the Sedimentary Cycle
Importance of velocity: equilibrium, aggradation and degradation
Transport: Dissolved load, Suspended load, and Bed load
Bed load: Saltation and traction
Deposition: alluvium
Some types of streams
Graded streams
Meandering streams
Braided streams
Stream piracy and Hell’s Canyon
Floods
Natural: typical every 5 years
Control of topography and infiltration on runoff
Flood frequency
