摘要

In recent years, there have been many failures of flood levees (river embankments) in France following river floods. The levees are mostly old structures for which few records are available. The matter is further complicated by the size of the levee infrastructure-more than 7,500 km in total length. The goal of this paper is to provide managers with methods and tools for assessing the performance of levees and to help them plan inspections, maintenance, and repair work. To do so, we developed a geographic information system (GIS) with the intention of incorporating it with the models for assessing levee performance. The first stage in this research is to model the failure mechanisms and identify performance indicators for each mechanism. The second stage is to assess levee performance with respect to each mechanism by aggregating the corresponding indicators. This paper describes the methods used for modeling levee failure and assessing levee performance. It also discusses the operational tools incorporated in the GIS.
