“…The morphological developments in estuaries and tidal basins are influenced by global environmental changes and human interference within and adjacent to them (Wang et al, 2015). Owing to SLR, strengthening of tidal asymmetry might be attenuated in GGB, where critical change from ebb to flood dominance was recorded due to anthropogenic coastal construction (particularly the Siwha Dike, see Suh et al, 2014).…”

“…showed that landreclamation construction caused significant changes in tidal amplitude throughout the Bohai Sea because of extensive natural and anthropogenic activities. Moreover, this tidal basin will be influenced by global environmental changes and human interference within and adjacent to it (Wang et al, 2015). Thus, the necessity of understanding tidal hydrodynamics is greatly increasing, if we are to figure out how tidal hydrodynamic change will continue or be altered by sea-level rise (SLR).…”

“…Initially, an increase in sediment load due to deforestation, changes in land use, or mining activities is followed by a sharp decrease in sediment load resulting from reservoir construction and riverbank reinforcement (Syvitski et al 2005;Walling and Fang 2003;Whitney et al 2014). Examples of this pattern of changes in sediment load are the San Francisco Bay-Delta (Barnard et al 2013), the Ebro (Guillén and Palanques 1997), and the Yangtze River Delta (Wang et al 2015). Human activities such as channel deepening Winterwerp and Wang 2013), land reclamation, and water deviation for agriculture and human consumption further impact the sediment dynamics of estuaries (Scavia et al 2002).…”

How can climate change and engineered water conveyance affect sediment dynamics in the San Francisco Bay-Delta system?

Suspended sediment concentration is an important estuarine health indicator. Estuarine ecosystems rely on the maintenance of habitat conditions, which are changing due to direct human impact and climate change. This study aims to evaluate the impact of climate change relative to engineering measures on estuarine fine sediment dynamics and sediment budgets. We use the highly engineered San Francisco Bay-Delta system as a case study. We apply a process-based modeling approach (Delft3D-FM) to assess the changes in hydrodynamics and sediment dynamics resulting from climate change and engineering scenarios. The scenarios consider a direct human impact (shift in water pumping location), climate change (sea level rise and suspended sediment concentration decrease), and abrupt disasters (island flooding, possibly as the results of an earthquake). Levee failure has the largest impact on the hydrodynamics of the system. Reduction in sediment input from the watershed has the greatest impact on turbidity levels, which are key to primary production and define habitat conditions for endemic species. Sea level rise leads to more sediment suspension and a net sediment export if little room for accommodation is left in the system due to continuous engineering works. Mitigation measures like levee reinforcement are effective for addressing direct human impacts, but less effective for a persistent, widespread, and increasing threat like sea level rise. Progressive adaptive mitigation measures to the changes in sediment and flow dynamics Climatic Change (2017) resulting from sea level rise may be a more effective strategy. Our approach shows that a validated process-based model is a useful tool to address long-term (decades to centuries) changes in sediment dynamics in highly engineered estuarine systems. In addition, our modeling approach provides a useful basis for long-term, process-based studies addressing ecosystem dynamics and health.
