Soft Bottom Low Flow Channel?A New Approach

by Paul A. Hindman, Urban Drainage and Flood Control, District, United States,



Document Type: Proceeding Paper

Part of: Water Resources Infrastructure: Needs, Economics, and Financing

Abstract:

In 1987, the City of Boulder, Colorado requested assistance from the Urban Drainage and Flood Control District (District) to repair a problem of cattails growing in the low flow portion of a creek. In 1988, the District retained the services of a professional engineering firm, to design a solution to the problem. The design involved a low flow channel eight feet wide with three foot high sand blasted vertical concrete banks. The bottom lined with cattail material salvaged during construction. Over time the channel bottom will aggrade with sediment which the District will remove to acceptable levels. To monitor the level of sediment, descriptive brass monuments were installed on top of the concrete walls.
