Martins Fork Lake Sedimentation Study. Hydraulic Model Investigation

摘要

This report presents the analysis of the unexpectedly high rate of infill experienced at Martins Fork Lake, located in Harlan County, Kentucky. The dam which impounds the lake is located in a drainage basin that has been actively strip-mined for a number of years. The study used the numerical model HL-1., 'Sedimentation in Stream Networks; authored by W.A. Thomas. Existing conditions were verified by subjecting the initial lake geometry to historical inflows and reproducing actual deposition patterns and storage loss in the lake. Future conditions under several alternative inflowing water hydrographs, inflowing sediment loads, and land use conditions were analyzed. Results are discussed and recommendations made to mitigate future loss of flood-control storage. Keywords: Sedimentation numerical models; Sediment deposition (edc)
