Morphodynamic investigation of Prairie Creek & design criteria for a proposed coho rearing/overflow channel
Scalici MJ. 1996. Morphodynamic investigation of Prairie Creek & design criteria for a proposed coho rearing/overflow channel
This paper discusses site conditions and methods for a project to restore wildlife habitat on a part of Prairie Creek just outside the boundaries of Redwood National and State Parks. The improvements would particularly benefit coho salmon by providing winter habitat, but would also enhance riparian habitat for other species. The project area was originally a side channel of Prairie Creek, and would be restored to active function using flows of an existing tributary to create a backwater, three pools, and two riffles. Reopening this channel would also lessen effects of periodic flood conditions at the site. This report summarizes field data, such as cross sectional and longitudinal surveys, regarding site topography, hydrologic and morphologic conditions, and water level elevations during flooding. It includes black-and-white photographs of 1995 flooding, tables with flood data, cross-sectional and other drawings, topographic maps. In addition to a lengthy site description, the paper also provides details of design elements for the channel. The two appendices contain channel cross section data, subsurface stratigraphy and soils data.
