| Title | Response of Dry Creek, California, to land use change, gravel mining and dam closure |
| Abstract | A 21.5 km reach of Dry Creek, downstream of Warm Springs dam, was studied in order to determine its responses to land use change, gravel mining and dam closure. Land use changes (1850-1870) caused aggradation and then degradation, but the channel was in equilibrium by 1900. Gravel mining in Dry Creek and the Russian River (1900-1950's) reduced base level of Dry Creek by 3m. The Channel degraded by an average of 3.2m, and by 1984 mean channel width and depth, at bankfull stage, had increased from 9.8 - 101.8m and from 1.4 - 5.8m, respectively. Channel longitudinal profiles were not significantly different; therefore, the major response of Dry Creek to the imposed changes was an increase of width. Dam closure (1983) did not cause the expected further degradation of Dry Creek because of channel armoring, tributary contribution of sediment, emplacement of 3 grade-control sills, and the presence of bedrock outcrops in the channel. |
