Thank you for the answers! The place were I would build the swales is quite flat. The water comes into our farm slowly, in strong rains episodes. The climate here is warm. We have already one swale working, (not hugel-swale) and I´m very happy with it. Now , I want to build another one next to this one, and I am considering to make a hugel-swale because we have a huge amount of broken trees in the forest due to an extremely hard snow episode.
