My goal is to extract diches (small stream) from a LiDAR DTM in a flat area. The problem is that I have a big data (13 GB) and some process like "breach depression" are too slow to be run in Whitebox GAT
The DEM's resolution is 0,5 m (square pixel) and I would like to keep it like this. What can I do?

Jens Kleb thank you for your answer
I'm not sure if I understood very well what you wrote (I'm not very expert in this study field)
Do you think that the pixel resolution x,y (50x50 cm) is not enough for extract ditches? (I think this is a precise accuracy)
Or do you think that the LiDAR-derived DEM is not the best for this application and is better the radar-derived DEM?
Best regards
Franco
