I put six bags of this in an old, old gully in an environmentally disturbed

Loose? The first good rain will wash them right out of there.

I presume that water that flows through the gully will be slowed down by the
heaviness of this material.

Hardly. Water weighs 8 lbs per gallon, and can shove rocks
around.

I will be adding more support and leaves to the gully and planting
along the sides.

Look into the practice of making brush dams, woven wicker
sediment traps, and gabions. It's way more effective than
dumping catalpa trash into a gulley.

You start the damming way upstream, with tiny dams along each
feeder, and work your way downstream making largre and larger
dams.
