Hi
I would like to obtain the talweg line (or the deepest longitudinal line) of a river reach. I have a mesh (features) from a hydraulic 2d model, and I converted it to raster.
I was thinking about creating a longitudinal line across the reach (1) and then create several perpendicular lines -profiles- separated x distance (2). Afterwards obtaining the values of some points across this profiles (3), and select those with the maximum value (4). Finally, join those points selected in every cross section (5)
I don't know how to do steps 2 and 5.
I wonder if you know a better way to do it, or if you can help me with the steps I don't know.
Thank you very much
