      Description
      Urbanisation affects both the volume and timing of sediment delivery in the catchment. This study presents influence of floodplain restoration on the sediment dynamics in the highly urbanised catchment, Johnson Creek, Portland, Oregon. The study incorporates a two-dimensional hydro-morphodynamic model for predicting flow and suspended sediment dynamics in the downstream of Johnson Creek, the East Lents reach, where the bank of river has been reconfigured to reconnect to a restored floodplain. The simulation scenario include event-based (10, 50, 100, and 500 year floods) deposition modelling of flood events and long-term modelling using the 64 historical events between 1941 and 2014.
