Development of numerical model for inverse modeling of confined Aquifer: Application of simulated annealing method

Abstract

The paper deals with the development of a numerical model for inverse modeling of groundwater systems based upon the simulated annealing (SA) global optimization method Galerkin's finite element technique is developed for computing the head distribution in a confined aquifer domain. The developed numerical model is applied to the synthetic aquifer involving a set of boundary conditions, source and sink terms to compute the system parameter (transmissivity) within the chosen nine zones of the aquifer Different data sets involving both steady and transient head values are used for these estimations. The results show that the developed model can be successfully used to obtain optimal estimates of the aquifer parameters. Based upon these information optimum model structure is also identified later from five different initial models.
