Estimated Flow-Duration Curves for Selected Ungaged Sites in the Cimarron andLower Arkansas River Basins in Kansas

摘要

Flow-duration curves for 1968-98 were estimated for 16 ungaged sites in theCimarron and lower Arkansas River Basins in south central Kansas. The method of estimation used six unique factors for flow duration, which were previously developed from a regionalized study of flow duration curves using a stream flow data for 1921-76. The method was tested on a currently measured, continuous-record stream flow-gaging station on the Little Arkansas River at Valley Center, Kansas, and was found to adequately estimate the computed flow-duration curve for the station. The low-flow parts of the estimated flow-duration curves were
