Uplift and piping are important failure mechanisms of levees in terms of their contribution to the total probability of failure of flood defense systems in the Netherlands. The reliability for this combined failure mode uses to be dominated by uncertain ground conditions, especially by the blanket thickness and the permeability of the aquifer. Such uncertainties can be reduced by incorporating additional information by means of Bayesian Updating. This study explores how active pore pressure monitoring can affect the piping reliability and how we can assess the uncertain effects of future monitoring campaigns for judging their (expected) cost-effectiveness.
