People living on and off the coast of New England will soon be at a greater risk from flooding due to heavier rain and rising seas caused by climate change. Closing the flood risk protection gap will require increasing the availability and uptake of insurance solutions, while minimizing loss through proactive risk mitigation. Sea-Level Change Curve Calculator Using the Flood Risk Reduction Standard for Sandy Rebuilding Projects. Climate variability (dry cycles to wet cycles) and land-use change play a significant role, but there is a large amount of uncertainty around the flood quantile estimates (the value of discharge corresponding to the 100-year flood), particularly if there isn’t a long record of observed data at a stream location. *FREE* shipping on qualifying offers. Analysis of Flood Re via an Agent-Based Model specifically for surface water flooding in London showed how climate change is expected to put pressure on this approach, for it does not present a sustainable long-term solution to flood insurance, as it does not provide any incentives to reduce risks.
