Q=vol w=width
V=velocity d=depth
Hydrography - graph above flow/ gauging station
River flow - saltation, plucking & quarring
Kolking - Whirpool, rounded basalt
Lahars or volcanic water or debris also
Abrasion and Pot holes
Knick point - stream bed over waterfall
Slope inverse function of discharge
Larger channels need less slope to flow
Temporary vs. ultimate base level
Floods - annual vs. 25, 50, 75 & 100 years vs. 125 yrs.
River sediment flow
Competence - Ability to transport sediment
Froude # is the degree of turbulence
Depends on velocity and depth
Capacity - sediment max of theoretical transmitted
Thalweg - line connecting max h2o depth of a channel
Anastomosing or anabranching channel
Straight channel if dredged is unstable
Meanders & 0 X B 0 W S
Neck cut off, point bar (inside)
Broad plains and aggrading
Grade - 10 variables in hydrolic geometry
ID= discharge, load & ultimate base level supply vs. transport limited
