Hi everyone. I am looking for advice as to how I can slow erosion on my property and incorporate that into the landscape. I have a few goals, on of them being growing some of my own food. I have read and watch videos about building swales and planting trees, bushes etc. on the other side of the swales. All advice will be appreciated as well as any good book on permaculture that has practical ideas to implement. I have a few questions in mind. How long do the swales have to be, depth, width? How far apart should they be from one another? Any other ways you have tried to stop erosion are also welcome. I am attaching a few pictures of the slopes with the slope percentage (which I calculated) so you can get a better idea of what I will be working with. BTW all these water goes on to a seasonal creek which runs though the entire property, which is also causing erosion because it slopes north to south. Maybe I can build some kind of pond system (permit required? dont ask/ dont tell? Any how that might be part of a different thread. Thank you in advance for you input.
