Kanning, W. (author), Bocovich, C. (author), Schweckendiek, T. (author), Mooney, M.A. (author)Piping failure of levees is one of the main contributors to flood risk. Piping occurs when the head difference over a levee results in uplift of the inland blanket, followed by backward erosion in the aquifer due to high local flow velocities. Whether piping occurs, highly depends on local geo-hydrological circumstances which are uncertain due...conference paper 2015

De Visser, M.M. (author), Kanning, W. (author), Koopmans, R. (author), Niemeijer, J. (author)Research to the failure mechanism piping (internal, backward erosion) in the Netherlands shows that the dikes require costly berms to meet the required safety standards. According to the Sellmeijer piping-formula, the d70 (70%-quantile of the grain size distribution by weight) is an important parameter in the resistance against piping. Therefore...conference paper 2015
