Efficacy of Hugelkultur swales in the Sub-Tropics.

Hello fellow permies!

How well do you think a Hugelswale will hold up in the sub-tropics?

More specifically; between two swales with excess water flow from spillways.

Here during the wet season the swales are subject to being blown when hard surface material is found in the berm of a swale.

This is what raises my question with hugelswale and how stable it will be in the extremes of the wet season, and how well it will hold up to extensive water run off.

If anyone has any experience, I would very much appreciate your help!

Thanks,

Jesse Leavitt
