Decorative ponds for houses or even bigger ones like lakes are widely used by landscaping architects.
If you construct a pond on the side slopes you sometimes put some small sized gravel and some plants.
The plants and gravel or soil sometimes slide down to bottom of the pond.
3 dimensional geosynthetic mats for erosion control or 3D mat type green slope materials may help for this purpose.
On the membrane you can cover with a protection (nonwoven geotextile) and use mat.
These mats can also be used in fish ponds.
For the noise reduction property of the mats please check fountain section.
