Channel mobility operations

This set of functions is for computing channel mobility metrics. Inputs to these functions are some sort of binary channel masks, and maps defining the fluvial surface (land area) over which the metrics should be computed. Functionality for fitting linear, harmonic, and exponential curves to the results of these functions is provided as well.

The functions are defined in deltametrics.mobility.

Hint

There is a complete Mobility Subject Guide about the organization of this area of DeltaMetrics and examples for how to use and compute mobility metrics.
