README.txt

Below is information on the files in this folder, the inputs to these functions, 
and how to run the processing described in Lefebvre et al. (2021).

Pro­cesses and Land­forms https://doi.org/10.1002/esp.5243

There are three main functions to do the processing
get_crest_troughlines.m = calculates the position and properties of crestlines
tidal_steep_faces.m = calculates the position and properties of tidal steep faces
tidal_bedform_properties.m = calculates the properties of BEP bedforms

An example of how to run the processing is given in example_processing.m
Many thanks to to Wasserstraßen- und Schifffahrtsamt Weser-Jade-Nordsee, Standort Bremerhaven 
for allowing us to share the data

The main input is with a 3D bathymetry (xr,yr,zr) from a (constrained) tidal environment. 
It is assumed that 
- xr is longitude/crosswise position
- yr is the latitude/streamwise position with ebb direction in increasing streamwise values
- zr is the depth

For tidal_steep_faces.m, user-input threshold values are to find the steep faces
tidal_bedform_properties.m uses results from the two other functions

The software was developped for data from the Weser Estuary with a grid size fo 2 m. It will
probably have to be adapated for data with higher resolution!

If you have any questions feel welcome to contact me at alefebvre@marum.de
I would be happy to work together to improve or fix any errors. Any feedback will be welcome!
