pyBenD stands for Python Bend Dynamics. This repository replaces ChannelPy repository.
This project sets the data structure to store channel centreline properties and centreline evolution (a set of successive position of a river centerline) through time. It provides methods to create cross-sections and measure meander bend geomorphic and kinematic parameters.
The methodology for channel point tracking algorithm is inspired from zsylvester/meanderpy.
A full documentation of the code can be found here
