| Abstract: | A 5-year, data collection and modeling study was conducted on Pheasant Branch basin in and near Middleton, Wisconsin. The objectives of the study were (1) to describe the streamflow characteristics, sediment transport, and stream channel morphology in the Pheasant Branch basin and (2) to relate the above factors to changes caused by urbanization and project the effect that urbanization will have on the hydrology and channel morphology of the study area. Suspended-sediment yields from the South Fork basin were the highest of all basins monitored. A comparison of storm suspended sediment loads between Century Avenue and the mouth indicated deposition of about 4,000 tons of sediment in the marsh between the two sites. Downstream from the fully urbanized part of the basin, the mean streambed elevation was lowered by almost 2 ft between 1971 and 1977, while the mean channel width increased by more than 35%. In other reaches of the stream, the mean streambed elevation was lowered by more than 1 foot. A rainfall-runoff model was used to simulate 68 years of summer flood hydrographs for (1) current land use, (2) projected urban development, and (3) complete urban development. The simulated mean annual flood peaks at U.S. Highway 12 would be increased by factors of 2.0 and 2.4 by projected and complete urban development, respectively. This would cause the channel width to increase by 40 to 50% and the channel depth to increase by 30 to 40%. (USGS) |
