摘要：

How useful are county soil surveys for estimating floodplain storage in fluvial sediment budgets? This paper compares data about accelerated sedimentation collected from field corings with information derived from threecounty soil surveys in southeastern Minnesota. Two soil surveys proved to be unsatisfactory data sources abouthistorical alluvium, but another survey was a more accurate source for one drainage basin. Even this third soilsurvey would require calibration for use in a geographic information system, because it was only the survey'smaximum estimate that agreed with the field data. Key Words: accelerated sedimentation, soil surveys, sediment budgets. © 1990 by Association of American Geographers.
