1D analytical models for morphology on short time scales

Type

Hydromorphological models

Basic principles

Fundamental equations for conservation of water mass and water flow momentum under the assumption of steady flow, spatially averaged over cross-section segments and time-averaged over all turbulent fluctuations. Equilibrium sediment transport predictor. Exner equation for conservation of sediment mass.

Outputs

Flow velocities, water depths, water levels, flow shear stresses. Sediment transport, bed level, erosion, sedimentation.
