In this case it really doesn't matter if it is from lidar or not. Anyway, you can a lot of useful information here (theory & GRASS commands): http://ncsu-geoforall-lab.github.io/geospatial-modeling-course/topics/flow_modeling.html http://ncsu-geoforall-lab.github.io/geospatial-modeling-course/grass/hydrology.html http://ncsu-geoforall-lab.github.io/geospatial-modeling-course/grass/simwe.html
