Hello. On a small agricultural test field of about 1.5 Ha, on which I made the DEM with a survey in the field, I am trying some simulation of rainwater drainage, with a comparison of the current situation, a situation of passages of the tractor with carriages according to straight lines, and a situation of passages according to a keyline design, curved. To modify the dem to keep up with the tractor tracks, I am using the r.carve module: I use a width of 0.4 meters and a depth of 0.07 (resolution of the DEM and of the region of 0.1). In the situation of straight carriageways, r.carve cuts ditches about 3 m deep (either using -n or not). Strange because in the situation of curved lines in keyline everything was fine. I don't understand how the module thinks, and what the default is. Thank you
