Reliability Assessment and Weak-Point Analysis of River Levees by Means of Failure-Logit-Models Levee failure-logit-models are based on the multivariate, statistical analysis of observations regarding the state and the performance of river levees in former flood events. As such models allow the reliability assessment for individual levee sections in case of floods, failure-logit-models can be used e.g. for inundation risk analysis considering levee failure or within levee maintenance projects. Thus they can contribute to modern flood risk management.
