I want to create a stream about 8ft long, 15 inches wide. Water pumped from
the pond, and returning via a small waterfall. I intend to use a dedicated
pump of 3,000lph. I need to work out the angle of fall for the stream to
create a natural looking flow. Stream won't be deep.....a few inches, but
will have water lettuce/cress anchored along it. Any clever people got ideas
please? :)

How about a fall of one in forty - what is used in drain piping.
