Title: Formation of stationary alternate bars in a steep channel with mixed-size sediment: a flume experiment

Author: Lisle, Thomas E.; Ikeda, Hiroshi; Iseya, Fujiko;

Date: 1991

Source: Earth Surface Processes and Landforms 16(5): 463-469.

Publication Series: Miscellaneous Publication

Description: Abstract - Alternate bars were formed by sediment transport in a flume with Froude-modelled flow and relative roughness characteristic of gravel-boulder channels with steep slopes. The flume (0.3 m wide x 7.5 m long) was filled with a sand-gravel mixture, which was also fed into the top of the flume at a constant rate under constant discharge. Channel slope was set at 0.03. Initially, coarse particles accumulated on incipient bar heads near one side of the flume and diverted flow and bedload transport across the flume toward a pool scoured against the opposite flume wall downstream. Alternate sequences of pools and coarse bar heads were thereby linked down the entire flume by interactions of sediment sorting, flow, and channel morphology.

Keywords: PSW4351, alternate bars, bedload transport, sediment sorting, flume experiment
