Detects the bankfull level of river cross-sections sampled from a DTM with the
maximum hydraulic depth method (A/W) described in: De Rosa, P., Fredduzzi, A.,
Cencetti, C. (2019). A GIS-based tool for automatic bankfull detection from airborne
high resolution DEM. ISPRS International Journal of Geo-Information, 8(11), 480.
https://doi.org/10.3390/ijgi8110480. The A/W curve is smoothed with a cross-validated smoothing
spline in pure Python (numpy/scipy): R and rpy2 are no longer needed. The optional
"thalweg" handling of multiple wet polygons follows an idea of HydXS (Garber and
Thompson 2024, Water Resources Research, doi 10.1029/2023WR035269).
The tools are available as Processing algorithms.
