I am running SWMM model, which requires the channel dimension data.
However, it is very difficult to get every channel in my study area
measuring. I took some samples. Now I have question to estimate the
channel depth. The data I have are channel width for each channel,
drainage area for each reach, DEM, and some channel depth samples. If
you know how to get the the channel depth estimation, please let me
know.
Many Thanks!
