| Abstract |
Seasonal movements of sediment in the Tamar Estuary have been estimated by recording variations in sediment levels at 30 sites evenly distributed along the length of the estuary through a 14 month period. A marked seasonal migration was observed in which sediment was gradually accumulated in the upper estuarine turbidity maximum zone during the spring and summer months. In winter, this sediment was redistributed into localised depositional sites in the mid-estuarine region. Regressions of sediment accumulation against river low indicate that internal cycling of sediment is primarily driven by changes in river flow. Particle fluxes and the total amount of material involved in this seasonal migration have been calculated and the potential mobile sediment replacement time has been estimated. |
