Change of Particle Composition from Fluvial into an Estuarine Environment: Rappahannock River, Virginia

J.W. Pierce, Maynard M. Nichols



SEM analysis of suspended material from the Rappahannock River estuary reveals changes in particle composition and the nature of particle association between fluvial and estuarine environments. Fluvial suspensions supplied by river flooding are enriched in single grains and very small floes whereas estuarine suspensions are enriched in aggregates mixed with single coated grains. Fluvial material is significantly modified as it passes into the estuarine environment by association with organic material and biota to form complex aggregates.
