What is the Erosion Equation?
|
is an expression of mass conservation that relates changes in volume of moving sediment above a bed to changes in bed elevation by sediment deposition and/or erosion.
|
|
Spatial change in what variable of the Erosion Equation affects erosion or deposition on a sediment bed?
|
Sediment deposition and erosion is primarily the consequence of a change in boundary shear stress, shear velocity, or mean flow velocity.
|
|
Temporal change in what variable of the Erosion Equation affects erosion or deposition on a sediment bed?
|
.
|
|
What three variables can be used to estimate the magnitude of the sediment flux and the volume of sediment in motion per unit bed area?
|
boundary shear stress, shear velocity, or mean flow velocity.
|
|
Is sediment deposition and erosion directly related to the local magnitude of the boundary shear stress, shear velocity, or average flow velocity?
|
not directly related
