UPLAND
upland rivers and streams are the fast flowing rivers and streams that drain elevated or
mountainous country, often onto broad alluvial plains.
Arguably the most important determinants are that of stream power and course
gradient. Rivers with a course that drops in altitude rapidly will have faster water flow
and higher stream power or “force of water”.
This in turn produces the other characteristics of an upland river- an incised course,
a river bed dominated by bedrock and coarse sediments, a riffle and pool structure
and cooler water temperatures.
