This study addresses the increasing risk of compound coastal flooding in San Francisco Bay due to climate change. It reveals that rare flooding events could occur annually with significant sea-level rises, and river discharge impacts are expected to extend further seaward under extreme climate scenarios. Overall, understanding these factors is essential for managing future flooding risks in the region.
The investigation into compound coastal flooding within San Francisco Bay focuses on how climate change-driven sea-level rise and increased river discharge affect flooding events. This research highlights that the frequency and severity of flooding risks are rising in the San Francisco Bay Area, yet these issues are not extensively studied. Results indicate that what are currently rare flooding occurrences may turn into annual events under significant climate change scenarios, particularly with higher sea-level rises of 1.0 to 1.5 meters. Furthermore, it is projected that future extreme water levels will shift from being predominately influenced by tides to being largely determined by sea-level rise in numerous locations throughout the Bay. In cases of extreme climate change, the influence of river discharge on non-tidal water levels in the North Bay is expected to extend approximately 15 kilometers further seaward.
The study of compound coastal flooding in San Francisco Bay examines how climate change factors, such as sea-level rise and increased river flows, contribute to the frequency and severity of flooding events. As the impacts of climate change become more pronounced, the implications for coastal flooding rise, prompting the necessity for robust analysis in often-overlooked areas like the San Francisco Bay Area. Understanding these dynamics is crucial for planning and mitigation efforts.
In conclusion, the research underscores the alarming potential for increased flooding events in the San Francisco Bay Area due to climate change. With predicted shifts from rare flooding to annual occurrences under high sea-level scenarios, it is crucial to comprehensively study these impacts to inform future adaptation strategies. As the region faces the dual threats of rising sea levels and changing river discharge patterns, proactive measures become imperative to mitigate potential damages.
