I wonder if the overlapping of the metal plates forming the side should 
be reversed - so that flow from the top down does not encounter the 
edges of the metal as now.  You want to minimise wear and the 
possibility of clogging that is inevitable when gravel and sand is 
washed through the device.

Similarly it would be better to replace the separate plates and rivets 
at the base with a single plate.  Better yet have an 'insert' plate that 
can be replaced as needed covering the base.  Wear and tear is a major 
consideration for sluice boxes.
