Dataset

Input files and model output for a schematized 1-D morphodynamic model of the Lower Rhine System (from Bonn in Germany to Vuren, Schoonhoven, and Keteldiep in the Netherlands)


These files are related to the manuscript " Climate Change Impacts on Flow Partitioning in a River Bifurcation System " submitted to Geophysical Research Letters.


The Input files include


- Model_cross_sections: cross-section data, with the main channel and floodplain width at each cross-section

- initial mean bed elevation: Initial mean bed elevation of all the branches

- initial bed composition: Initial bed and subsurface composition per grid cell formatted as input to SOBEK RE

- internal and external morphological boundary conditions: Sediment flux at the upstream boundary and nodal point relations at the two bifurcation nodes formatted as input to SOBEK RE

- Boundary condition_Upstream discharge: Hydrograph at the upstream boundary for the reference case and the scenarios

- Boundary condition_Downstream water level: Water level at the downstream boundaries for the reference case and the scenarios (Please check SI to separate which boundary condition fits with which scenario)

- GRAINP: Mixed size sediment input file for SOBEK RE


A list of runs used in the manuscript is also added.

Model results


- flow_discharge_output.xlsx : Flow discharge at Lobith and the upstream part of the bifurcates for all the model runs

- bed_level_output.xlsx: yearly averaged bed level for the entire reach for all the model runs

- Dg_transport_output/DG_surface_output: 20-year averaged geometric mean grain size of the flux and bed surface over the entire reach for the reference case, hydrograph scenario Hn, and combined scenario Hn-SSP 585


In addition, the field data collected by Rijkswaterstaat on bed surface grain size in the Dutch Rhine in 2020 (2020_bed_surface_data.xlsx) is also included. These data have been used as information to derive the model input grain size fraction content. The data has been averaged over width; we only used data for locations where right, left, and center samples were available.
