If you plant chunks of liriope in those wash places, it will stop it. It will come up through the wire, and make a mat that will hold everything in place. My birds don't eat it, but they have lots of grass.I know Diva! We have an erosion problem. We have put rocks and gravel and it just washes away and they pull the gravel out. The gap is zero in some places and 8 inches in another. DH bought poultry netting to try to overlay the bottom of the fence and bury it into the ground a bit. Neither of us are good diggers because of back and breathing problems. We are going to try to get it worked out tomorrow.
