Beach widths and slopes

[rileetho]

Hi,

I'm having some issues with beach width calculations - I have two cradles next to each other pointing in opposite directions up and down the same beach, but beach widths between cradles are big, one cradle/set of images is giving widths double that of the other. How exactly are beach widths calculated in the code?

Also, wondering if I can get beach slope estimates out of CoastSnap analysis?

Thanks, Rilee

Beach widths are calculated from the start of your transects, so defining these transect locations will be important. You should try to make your transects start at the sandy section of the beach. If you want to have more carefully defined transects then this will require manually editing the positions (e.g. in QGIS) and importing them into Matlab format (this will require experienced coding however).

Beach slopes can in theory be estimated from the shorelines using the same approaches we do with satellite derived shorelines (https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2020GL088365). There is no in-built code to do this however
