The UWM Dept. of Geosciences research flume is essentially a laboratory-controlled linear stream within a large glass tank, that allows for observation and research of the erosion, transportation, and deposition of sediment, as well as various other geological and engineering studies. The flume is one of the larger research flumes in the country (measuring approx. 34' x 4' x 4') and is loaded with approximately 15 tons of sand and 1,000 gallons of water. Unlike a natural stream, where the velocity is controlled by the gradient, channel characteristics and discharge, the stream velocity within the flume is controlled manually, using a variable speed, 30 horsepower, water and sediment recirculating turbine pump.

During this project you will be allowed the opportunity to vary the stream velocity to observe the resultant flow characteristics and sedimentary bedforms. The research flume project will provide an excellent opportunity for you to see firsthand the relationship between stream flow and sedimentary bedforms. Bedforms are features formed on a stream bed by the interaction between stream flow and sediment. The formation of bedforms is primarily dependent upon the relationship among water depth, stream flow velocity, and sediment supply. Bedforms known as ripples are, by definition, 0-4 cm high and bedforms known as dunes are greater than 4 cm high.
