Effects Of Adding Sediment To A Fresh Water Thin Mat Floating Marsh, Kate Carpenter
Effects Of Adding Sediment To A Fresh Water Thin Mat Floating Marsh, Kate Carpenter
LSU Master's Theses
Floating marshes are wetlands of emergent vascular vegetation which have a significant mat of live and dead roots, decomposing and dead organic material, and mineral sediments. This mat moves vertically as ambient water levels rise and fall. These marshes have unique hydrology in that overland sheet flow is reduced or eliminated leaving no inorganic sediment input, but there is extensive belowground water exchange. The effect of significant sediment introduction into wetlands with floating marshes is unknown. The purpose of this study was to observe the marsh mat response to Mississippi River sediment addition and measure species composition change and growth …
