How to Build a Recirculating Stream Table
(Adapted from MRHOLLISTER.COM, 10/9/2017)
A stream table can be used to demonstrate many water-related concepts and principles, including flow rate, velocity,
channel slope, erosion, and deposition. This demonstration can also illustrate stream bank meandering, flood plains, and
stream bank stabilization. Because it is easy to transport, setup, and operate, the stream table can be used for a wide
range of venues where time and space is limited. This design requires a 110/120 Volt power source and 3-4 gallons of
water.
