I have the boundaries and centerline of a river.
The Thalweg line defines the deepest elevation of a watercourse (see Image taken from Google). I do not have accurate enough bathymetry or Digital Elevation Models to determine the proper deepest elevation of a river channel.
I would like to know if it is possible determine the Thalweg line of the river without the bathmetry?
It looks like the Thalweg line follows a predictable pattern where it hugs the outside curve of a river when it meanders and is in the center of the river with it is straight.
I am using ArcGIS 10.1 with all licenses available, and I am familiar with python.
