Comparative Aspects of Computerized Floodplain Data Management

The evolving floodplain management policies in Australia, the United Kingdom, and the United States are reviewed and compared. In each country, computerized floodplain information processing and retrieval systems have been designed for evaluating flood mitigation schemes. However, the information systems differ in detail and reflect the different aims and objectives of the organizations from which they have originated. Nevertheless, the general trend within each country is for national standardization of methodologies to promote consistent floodplain management.
