Contemporary stream sediment loads are dubious indicators of regional denudation. Recent analysis of ten river basins in the southeastern United States indicates that of the material eroded from upland slopes since European settlement, only about 5 percent has been exported. The remainder, alluvium and colluvium, will probably not be exported because of extensive reservoir impoundments.
