Document Summary

Gds where = density of water, g = gravity, d = water depth, s = slope. Increase in water depth and/slope = decrease in shear stress. As velocity increases, stream lines have to flow over particle, water moves more quickly to get on top of it, moves in a parcel. Velocity differences between the top and bottom of particle create a vertical pressure gradient (lift force) Suspended load particles suspended above the channel bed by turbulent eddies. Bed load particles in continuous or regular contact with the channel bed. Dissolved load solutes (anions and cations) derived from weathering processes. Maximum discharge that can be obtained within the channel before enters the floodplain. Hydraulic radius r = a/pw where r = hydraulic radius (m), a = cross-sectional area (m2), pw = wetted perimeter (m) A sediment rating curve is the relation between the sediment and the river discharges.
