Uncertainty quantification in the coastal aquifers using Multi Level Monte Carlo

Problem: Henry saltwater intrusion (nonlinear and time-dependent, describes a two-phase subsurface flow) Input uncertainty: porosity, permeability, and recharge (model by random fields) Solution: the salt mass fraction (uncertain and time-dependent) Method: Multi Level Monte Carlo (MLMC) method Deterministic solver: parallel multigrid solver ug4
