Abstract
Transport of seston and DOC was examined during storm flows in a disturbed and a natural blackwater, coastal plain stream. The disturbed stream had fewer retentive devices due to destruction of riparian vegetation by thermal effluents. Concentrations of seston declined linearly in both streams as the storms progressed. Particulate organic carbon concentrations were higher in the natural streams. However, at baseflow the relationship was reversed. Dissolved organic carbon did not change during storm flows. The retentive devices in the natural stream were ineffective at reducing transport during storm flows. The relationship between storm flows, retentiveness, and carbon transport may effect the diversity and density of invertebrates.
