Abstract

This paper evaluates how agricultural land use influenced the relative responsiveness of floods, erosion, and sedimentation to extreme and nonextreme hydologic activity occurring in watersheds of the Upper Mississippi Valley. The chronology of alluvial activity since settlement is recorded by a variety of benchmarks that include early surveys, historical artifacts, trace-metals of known age associated with lead and zinc mining, newspaper records of large floods, and historical instrumental observations of climate and river flows. Comparison with alluvial activity that occurred during natural vegetation conditions of the pre-agriculture Holocene shows that landscape sensitivity has been greatly magnified by agricultural land use
