A series of models are linked to investigate responses of California's San Francisco Estuary-Watershed system to two contrasting scenarios of climate change, and nine indicators of changing climate, hydrology and habitat quality are presented.
Elevational Dependence of Projected Hydrologic Changes in the San Francisco Estuary and Watershed

A large dinoflagellate bloom that developed in San Francisco Bay during September2004 is described, suggesting that some redtides are responses to changes in local physical dynamic that are driven by large-scale atmospheric processes and operate over both the event scale of biomass growth and the seasonal scale that shapes the bloom community.
Natural and management influences on freshwater inflows and salinity in the San Francisco Estuary at monthly to interannual scales
- N. Knowles
- Environmental Science
- 1 December 2002
Both natural and management inflow and salinity signals show strong interannual variability and year-to-year variations in all signals are very large, which can greatly exceed the range of management effects on salinity in the estuary.
Potential Inundation due to Rising Sea Levels in the San Francisco Bay Region
- N. Knowles
- Environmental Science
- 2009
An increase in the rate of sea level rise is one of the primary impacts of projected global climate change. To assess potential inundation associated with a continued acceleration of sea level rise,…
