Abstract
Distances traveled by wet and dry leaves of maple, beech and oak prior to entrainment on obstacles were determined in Woodcock Creek, Crawford County, Pennsylvania [USA], between April 25 and May 14, 1976. Over all leaf species and all dates, the mean distance traveled by wet leaves was 192 m (range 106-557 m) and by dry leaves was 226 m (range 132-333 m). The distance necessary for entrainment of all leaves entering at a point was 886 m (range 490-2558 m) for wet leaves and 1040 m (range 606-1535 m) for dry leaves. Differences in drift distances among species were related to leaf size, and shape and differences in drift distances among dates were related to changes in discharge.This publication has 1 reference indexed in Scilit:
