Description :
Changes in land use practices following European settlement in the 1830s produced accelerated sedimentation on virtually all valley floors in the Blue River Watershed, Wisconsin. The contamination of sediments by Pb and Zn mining allowed to calculate cross-valley rates of flood plain sedimentation for three time periods : the pre-mining period (1830-1900), the mining period (1900-1920), and the post-mining period (1920-1997). The AA. also examine geomorphic lags in channel adjustments that influence sedimentation.
