At What Scales Does A River Meander? Scale-Specific Sinuosity (S3) Metric For Quantifying Stream Meander Size Distribution
--
https://doi.org/10.1016/j.geomorph.2023.108734 <-- shared paper
--
“HIGHLIGHTS:
• Scale-specific sinuosity (S3) summarizes bend sizes of linear features and associated contributions to sinuosity across a range of scales.
• The S3 plot is analogous to a frequency histogram of bend sizes, like a fingerprint or a spectral signature
• The S3 is an easily computed metric to assess influential scales in bend patterns of linear stream features
• The paper formalizes a relation between sinuosity and fractal dimension..."

There are still issue especially with forests patches still visible, but it can only get better from here. Tech documentation is at: https://doi.org/10.21203/rs.3.rs-2277090/v2

The #geomorphometry society launched the "coffee talks" series of seminars - an opportunity to discuss, exchange, initiate, train, present, outline topics, research agendas, papers, questions in an informal way between our main biannual conferences.
Next up is John Lindsay from University of Guelph - talking about WhiteBox for Geomorphometry - on 2022-12-07
Full schedule and details here:
