=Numerical meander models=<br />
==Type==<br />
Hydromorphological models<br />
<br />
==Basic principles==<br />
Linearized fundamental equations for conservation of water mass and water flow momentum, spatially averaged over water depth and time-averaged over all turbulent fluctuations. Linearized parameterized relation for effect of helical flow on bed shear stress direction.<br />
Empirical bank migration predictor.<br />
Possibly linearized equilibrium sediment transport predictor. Possibly linearized empirical relation for effect of sloping beds on sediment transport magnitude and direction. Linearized Exner equation for conservation of sediment mass.<br />
<br />
==Outputs==<br />
Flow velocities, water depths, water levels, flow shear stresses.<br />
Sediment transport, bed level, bank erosion, meander migration.<br />
