Mammal bioerosion is an emergent threat to the functionality of levees. In present paper, problem assessing failure probability levees affected by mammal addressed. A fully bivariate description peak flow discharge and flood duration combined with a deterministic unsteady seepage model obtain suitable variably disturbed levee response observed natural variability floods. Monte Carlo analysis al...

In reliability engineering focused on the design and optimization of structures, the typical measure of reliability is the probability of failure of the structure or its individual components relative to specific limit states. However, the failure probability has troublesome properties that raise several theoretical, practical, and computational issues. This paper explains the seriousness of th...

Firstand second-order reliability methods (FORM and SORM) are applied as alternatives to the Monte Carlo simulation method in the probabilistic analysis of groundwater contaminant transport and remediation. A two-dimensional finite-element model is interfaced with a reliability analysis program to account for uncertainty in aquifer media. Hydraulic conductivity is modeled as a spatial random fi...
