I want to map these river geoforms with as little subjectivity as possible. I have a high resolution DEM generated by drone data.

Perhaps this professor may have the answer
Dear Mr. Paz,
I is one of the most common desires among some geologists to sit on a swivel chair in a study and map the geology of the world. You can also be more precise and extend it to sedimentology or shift to geomorphology which are the basic disciplines dealing with these fluvial landforms you mentioned here. But there is no geology without field geology. At the beginning is a meticulous field work where you have to collect as many data typical of the various landforms in terms of grain size, rock color , topographic data correlation with landforms etc. If you have collected these data which may be supplemented with aero and ground geophysical ones you can try and find the most appropriate tool, e,g., satellite-, aircraft- and drone.- based remote sensing devices. There is no way other than normalizing your aero data to the ground data. A topographic classification based upon different altitudes only can be disastrous because you have to understand how the hydrodynamic and hydrography are intertwined. Drones can only successfully be used as there are calibration points where they have been tested with regard to the correlation between aero-geological/geomorphological data and data obtained from field work. Your landform types fans, terraces and floodplains have been derived from various landform series and generations. This may additionally complicate the situation
