All things green, outdoors, and nature-y. Whether it's animals in their natural habitat, hiking trails and mountains, or planting a little garden for yourself (and everything in between), you can talk about it here.

There are tons of bioengineering concepts out there, not just specific to rivers, though river engineering is a cool rabbithole!
I know someone who does geomorphic design - basically redesigns disturbed landforms (before guys like me come and put soil on them). It's all about water management and movement, and erosional modeling. Really cool stuff that I am too dumb to do. She's probably on the list of the top 3 smartest people I know.
There's so much out there, and it's all so fascinating! I felt like this discussion was apropos with the coming of autumn rainstorms for much of the US, since every bit of water slowing and sequestration can have a huge impact on the rest of the watershed.
Don't sell yourself short! Your specialized knowledge is really cool stuff too, speaking as someone who couldn't tell a mollisol from a podzol. It's folks like you and your ostensibly scary-smart colleague that empower generalists like myself to approach regenerative designs at a single steward scale.
