Title: Major floods, poor land use delay return of sedimentation to normal rates

Author: Anderson, Henry W.;

Date: 1972

Source: Res. Note PSW-RN-268. Berkeley, CA: U.S. Department of Agriculture, Forest Service, Pacific Southwest Forest and Range Experiment Station. 4 p

Publication Series: Research Note (RN)

Description: Recovery from flood-accelerated sedimentation affects both estimates of long-term average deposition and short-term monitoring of changes. "Years to return to normal" for 10 watersheds in northern California after a major flood accelerated sediment concentrations were analyzed. Returns to normalcy took from 0 to 9 years; rate of decline was related to both amount of initial acceleration by the flood and differences in watersheds. years to recovery increased with these four factors: coefficient of path lengths in the watershed, area of poor logging, area of steep grassland, and percent of area in sedimentary rock types Cenozoic or younger.

Keywords: watershed management, forest management, streamflow, logging effects, floods, sediment transport, sedimentation, water quality, forecasting
