Stream and rills

Stream and rills are quite easy to construct as all the water is contained within the same area and re-circulated by a sump pump
With a stream or rill type stream the key is to have a slightly down hill slop not to step just encough to allow the water to run down hill
The volume of water can be ajusted by setting the pump to add more water to flow down the stream from a collection sump at the base of the stream or rill
