Urban Soft Bottom Low Flow Channel?A New Approach

Abstract:

In 1987, the City of Boulder, Colorado requested assistance from the Urban Drainage and Flood Control District (District) to repair an all too familiar problem of cattails growing in the low flow portion of a creek. The creek ran through a highly developed residential section of the City. After several meetings, the city of Boulder, the Engineer, the District and the local citizens came up with a design which met with the approval of all parties involved. The design included a low flow channel 8 ft wide with 3 ft high sand blasted vertical concrete banks. The bottom was 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.
