Multiple Scales of Suspended Sediment Dynamics in a Complex Geometry Estuary
Av Fernanda Achete, 2018.Del av serien IHE Delft PhD Thesis Series.
This study contributes to investigate and forecast turbidity levels and sediment budget variability at San Francisco Bay-Delta system at a variety of spatial and temporal scales applying a flexible mesh process-based model (Delft3D FM). It is possible to have a robust sediment model, which reproduces 90% of the yearly data derived sediment budget, with simple model settings, such as applying one mud fraction and a simple bottom sediment distribution. This finding opens opportunities for modeling less monitored estuaries.
Comparing the Sacramento-San Joaquin Delta and the Alviso Slough, a classification for estuaries regarding the main sediment dynamic forcing is proposed: event-driven estuary (Delta) and tide-driven estuary (Alviso Slough). In the event-driven estuaries, the rivers are the main sediment source and the tides have minor impact in the net sediment transport. In the tide-driven estuaries, the main sediment source is the bottom sediment and the tide asymmetry defines the net sediment transport.
