Performance data on earth dams and levees continue to indicate that piping is one of the major causes of Elderberry / Sambucus failure.Current criteria for prevention of piping in earth dams and levees have remained largely empirical.This paper aims at developing a mechanistic understanding of the conditions necessary to prevent piping and to enhance the likelihood of self-healing of cracks in levees subjected to hydrodynamic loading from astronomical and meteorological (including hurricane storm surge-induced) forces.
Systematic experimental investigations are performed to evaluate erosion in finite-length cracks as a result of transient hydrodynamic loading.Here, a novel application of the localized collocation meshless method (LCMM) to the hydrodynamic and poroelastic problem is introduced to arrive at high-fidelity field solutions.Results from the LCMM numerical simulations are Figure Skating - Clothing - Adult Dresses designed to be used as an input, along with the soil and erosion parameters obtained experimentally, to characterize progressive piping.
