Model predictions of global delta land area response to sea-level rise
This github repository contains code and datafiles to reproduce findings published in:
Nienhuis, J.H., & van de Wal, R.S.W. (2021). Projections of global delta land loss from sea-level rise in the 21st century. Geophysical Research Letters, 48, e2021GL093368. https://doi.org/10.1029/2021GL093368
loads data from
- Past sea level rise (1900-2015): Dangendorf et al (Nature Clim. https://www.nature.com/articles/s41558-019-0531-8)
- Future sea level rise (2007-2100): Oppenheimer et al (SROCC Ch. 4, https://www.ipcc.ch/srocc/)
- Vertical land motion: Shirzaei et al (Nature Rev., https://www.nature.com/articles/s43017-020-00115-x) and matches it with global delta river mouths. output: export_data/GlobalDeltaSeaLevelData
this file loads cross-sectional profile information from SRTM15+ and extracts delta widths and lengths. It uses a subfunction called "get_deltaprofile.m". additional data is loaded from Edmonds et al., Nature Comm, https://www.nature.com/articles/s41467-020-18531-4. We use their length/width data to check/validate our automatic width extraction and also replace our automatically obtained values where possible output: export_data/GlobalDeltaProfile
this file loads delta morphology from GlobalDeltaProfile and sea level changes from GlobalDeltaSeaLevelData to produce land area change estimates for global deltas it uses the function get_deltachange.m and get_deltachange_montecarlo for individual delta estimates incl uncertainty output: export_data/GlobalDeltaSeaLevelResponse
contains .mat and .nc data files that are generated by the scripts mentioned above.
contains scripts for the figures published in Nienhuis & van de Wal, GRL 2021
