Keeping gravel on bank with weed mat

I have a site with an "ornimental ditch" running down one side of the garden, both sides have weed suppressant matting covered with large gravel/slate etc.

The problem is the stones are sliding down into the ditch (which has pumped water up the garden and runs back through the ditch

Any ideas to keep the stones in place? Cust has now black patches of matting appearing and has asked me to bring in more stones, he had enough in the first place!

Not sure I understand your problem. Is it a designed stream/pond with a created water runoff.

Are your stones round? That isn't going to help the situation. The other thing to try is placing large stones/boulders (not sure what kind of stone you are dealing with) to break up any "gushes" of water that may be taking place. Kinda like creating natural damns to control the force of the water. Which brings up, can they/are they willing, to slow the flow of the water?

Water is pumped up hill in plastic pipe then runs back through the ditch to give a running water effect. The stones/slate are 3-4 sizes nothing more that 2" laid on the "banks" each side.

Because the weed membrane has no "grip" they are sliding down into the ditch. Water does not touch them on the banking.

I need to find a way to keep the on the membrane, will take a picture next time I'm there.
