Document Summary
Stream channels --> we are interested in them because they change the landscape, they drain landscapes and carry material from erosional uplands to depositional lowlands and coastal environments. They can respond to different perturbations over different timescales --> different channels responds in different ways. Streamflow: the main, key control on channel processes, the amount of water in the channel (over a short time frame) Climate --> the main control of streamflow, drives processes, how much water does it actually have (as affected by the hydrological cycles, rainfall, and etc. ) Tectonic activity: the key control on geological processes and over geological time scales (over millennia/long time frames), movement of plates. Rivers are not just singular systems, but includes fluvial habitats (incorporates both vegetation and animals), which affects different things (they are strictly related to them) Sectional area of the channel and the flow velocity) Defined by the cross sectional area (acs) x the flow velocity (average flow of velocity)
