  • local flow depths from this surface yielded estimates of the bed elevation that were then combined with LiDAR topography for exposed areas to create a composite representation of the riverine terrain. The accuracy of this terrain model was assessed via
  • comparison with detailed field surveys. A map of elevation residuals showed that the greatest errors were associated with underestimation of pool depths and failure to capture cross-stream differences in water surface elevation.

  • The AA. test hypotheses on morphodynamic scenario modelling and data of the upper Columbia River. Initial and boundary conditions for the modelling were derived from field data. A 1D network model was built based on gradually varied flow equations
  • , sediment transport prediction, mass conservation, transverse slope and spiral meander flow effects at the bifurcations. The number of channels and crevasse splays decreases in a downstream direction. These observations concur with bed sediment overloading
