摘要：

To understand the nature of increasing flood damage in the United States, accurate data are needed on costs and vulnerability associated with flooding. The National Weather Service (NWS) is the only organization that has maintained a long-term historical record of flood damage throughout the country. The NWS estimates are obtained from diverse sources, compiled soon after each flood event, and not verified by comparison with actual expenditures. This paper presents results of a comprehensive reanalysis of the scope, accuracy, and consistency of NWS damage estimates from 1926 to 2000 and recommends appropriate methods for data use and interpretation. Estimates for individual flood events are often quite inaccurate, but when estimates from many events are aggregated the errors become proportionately smaller. With the precautions described in this paper, the reanalyzed NWS damage estimates can be a valuable tool to aid researchers and decision makers in understanding the changing character of damaging floods in the United States.
