Open WL Archief (OWA)

Over het archief

Het OWA, het open archief van het Waterbouwkundig Laboratorium heeft tot doel alle vrij toegankelijke onderzoeksresultaten van dit instituut in digitale vorm aan te bieden. Op die manier wil het de zichtbaarheid, verspreiding en gebruik van deze onderzoeksresultaten, alsook de wetenschappelijke communicatie maximaal bevorderen.

Dit archief wordt uitgebouwd en beheerd volgens de principes van de Open Access Movement, en het daaruit ontstane Open Archives Initiative.

Abstract

Breach formation can be initiated by various geotechnical failure mechanisms. Evaluation ofthese mechanisms usually requires an enormous amount of data which is currently not available inFlanders. Therefore, a conceptual method for the estimation of breach sensitivity along waterways hasbeen developed by Flanders Hydraulics Research. The method can be executed based on a limitedamount of data which is currently available and avoids the need to perform expensive and timeconsuming large scale field surveys. For each failure mechanism, readily available strength-parametersare weighted and the outcome is the ‘failure index’ for the considered failure mechanism. These indexesallow to estimate where breaching is likely to occur. In addition, at identified critical sectors and/or wherehigh damage costs can be expected, a detailed statistical approach accounting for the uncertainty ofestimated parameters is suggested and hence, ends up with failure probabilities at these locations.
