Bank retention of very small natural pond

My client is worried about the bank soil eroding into the pond next to his path used by a ride on mower.

3 metre diameter natural pond/ large hole in Essex clay loam.

Bulrushes swamped it. It drys out in summer.

A sleeper has been set in the side at ground level where the path runs past the pond.

Excess water runs off the garden and into the pond in the wet season and this has caused some soil to get washed into the pond under the sleeper so the sleeper has a pocket under it only 50mm.

The client suggested digging out the sleeper and installing a wire mesh. Wire mesh is used on roadside cliffs and I have seen it used on some banks.

Can any premies offer some experience with such a situation?

Simplest solution: Keep the ride on lawn mower off of the bank.

Use a swing blade.

The old boy loves his ride on so not an option tho i love the intention.

You think it is the ride on that is the problem rather than general run off and erosion?

I think i have answered my own question as it is this spot in particular that appears to be the problem.

Anyway what I really want is some guidance in installing a retention method such as wire mesh
