Abstract

This study investigates the consequences of flocculation for sediment flux in glacier-fed Lillooet Lake, British Columbia, based on density, fractal dimension, in situ profiles of sediment concentration and size distribution, and settling velocity equations presented in the literature. While turbidity currents undoubtedly occur in Lillooet Lake, the results demonstrate flocculation as an adjunct process linking discharge, lake level, macrofloc flux, bulk density and microlaminations. In situ measurements of sediment settling velocity in glacier-fed lakes are required to better constrain flux rates, and permit comparison between flocculation in lacustrine environments with existing studies of estuarine, marine and fluvial flocculation
