Corte Madera Marsh, located in northern San Francisco Bay, California, is experiencing shoreline erosion. Determining whether the eroded sediment is exported to the bay or imported via tidal channels and deposited on the marsh platform is critical to understanding the long-term response of the marsh to wave attack and sea-level rise. Quantifying water-column sediment flux helps to characterize the role of tidal channels in this process, and water discharge is a key component of sediment flux. Tidal creek ...
