Abstract

The purpose of this research was to identify the forcing factors and processes of sediment transport in Perdido Bay. Data were collected from Perdido Bay in July 2011 and used in the development of a three-dimensional sediment transport model using EFDC as well as in the estimation of a sediment budget. Water and bed samples, water quality readings for salinity, temperature, dissolved oxygen, turbidity, depth, and pH, and velocity measurements were collected. Using field and historical data, an EFDC model was created to simulate the processes of salinity and sediment transport. The model successfully demonstrated the movement of sediment through the bay and proved the existence of a turbidity maximum in the northern bay. From this research, it was determined that freshwater inflow is the primary forcing factor in sedimentation and is the main contributor to sediment entering the bay.
