Examples of data combining techniques for assessment of urban flood defences
Exemple de technique de combinaison de données pour le diagnostic des ouvrages de protection contre les inondations en milieu urbain
Résumé
Traditional assessment methods of flood protection embankments rely on a set of data to reach the assessment. In such a traditional framework, it is difficult to use additional information for the assessment, even if this information is very valuable. In another paper (Van der Meij et al., 2012), a theoretical framework is presented on how to combine fundamentally different data types and data sources. This paper shows through a number of examples how this theory is applied at different stages of the analysis. In all examples, the initial approach only uses a part of all available information. It is shown that it is very well possible to incorporate all relevant information and it is therefore recommended to register them in a geo-referenced system for later use in assessment. The presented data combining techniques could be implemented in existing reliability tools that are currently being used by managers and engineers in different countries.
