This study analyzes the escalating risks of compound coastal flooding in the San Francisco Bay Area due to climate change. Findings suggest that rare flooding events could become annual occurrences under significant sea-level rise, highlighting shifts from tidal dominance to sea-level rise influences on future water levels.
This investigation addresses the complex challenges posed by climate change in relation to compound coastal flooding within the San Francisco Bay Area. It emphasizes the significant effects that rising sea levels and increased river discharge will have on the frequency and severity of flooding incidents. Despite the growing risk associated with compound coastal flooding due to climate change, this phenomenon remains inadequately studied in the region, warranting more comprehensive research efforts.
The findings indicate that flooding events currently classified as rare may occur every few hundred years under existing climate conditions. However, with anticipated climate change leading to substantial sea-level rise—between 0.5 meters to as much as 1.5 meters—these flooding occurrences could escalate to an annual basis. Moreover, this study predicts that the present tidal regimes, which currently dominate water levels, will increasingly be overshadowed by sea-level rise in many Bay locations over time.
Additionally, the influence of river discharge on water levels in the North Bay is expected to significantly extend, reaching approximately 15 kilometers further seaward under scenarios of extreme climate change. Such indicators underscore the urgent need to understand the multifaceted risks associated with compounded flooding in the region as climate dynamics evolve.
The effects of climate change are becoming increasingly pertinent, particularly concerning coastal regions like the San Francisco Bay Area, which faces unique challenges due to its geographical characteristics. The interplay between rising sea levels, increased precipitation, and river discharge forms a crucial aspect of climate risk management. Understanding these interactions is critical for developing adaptive strategies to safeguard communities and ecosystems against the looming threat of compounded flooding that is largely unaddressed at present.
In summary, this study highlights the rising threat of compound coastal flooding in the San Francisco Bay due to climate change. It reveals a concerning shift from rare flooding events to more frequent occurrences as sea levels rise, alongside the expanding influence of river discharge. As the region prepares for worsening climate impacts, urgent research and adaptive measures are imperative for mitigating risks associated with compounded flooding.
