Inverse modeling application for aquifer parameters estimation using a precise simulation–optimization model

open access: yesApplied Water Science, 2022
In this research, a simulation–optimization (S/O) model is used in order to estimate aquifer parameters on two aquifers. In this model, meshless local Petrov–Galerkin (MLPG) is used for simulation purpose and modified teaching–learning-based optimization
