Ok, looks like I got some good info. I'll post back in a few weeks
after its all in place.
I'm probably going to embed a large number of rocks/stones into the
sand to help support
the sides of the stream to lessen the soil shift problem. Maybe
burying concrete paving
stones also, since they have a large surface area and will dissipate
weight when walking
around it.
