Input files and model results for a schematized morphodynamic model of channel response of the lower Rhine River to climate change and human intervention.
These model files are related to the manuscript Centennial Channel Response to Climate Change in an Engineered River.
Input files (for modeling tool SOBEK-RE) include:
- cross-section data, with main channel and floodplain width at each cross section (cross-sections.txt)
- initial mean bed elevation (bedlevel_ini.txt)
- initial bed surface and substrate composition per fraction (gs_ini.txt)
- boundary conditions for the reference case and (climate) scenarios: upstream water discharge, upstream sediment flux, downstream water level (#scenario#_QKoln.txt, #scenario#_BaseLevel.txt, #scenario#_SedFlux.txt)
Model results (ModelRuns_2050-2100.xlsx) include for the reference case and climate scenarios:
- Main channel bed elevation at 2050 and 2100
- Geometric mean grain size at 2050 and 2100
In addition, the field data collected by Rijkswaterstaat on bed surface grain size in the Dutch Rhine in 2020 is also included (grainsize_field_DutchRhine.xlsx). These data has been used as information to derive the model input grain size fraction content.
