Ground water flow modelling using visual modflow

Abstract

Groundwater model has become an essential tool for hydro geologists to perform various tasks including the assessment and prediction of groundwater, the detection of groundwater pollution etc. The large-scale regional groundwater systems are simulated using various user-friendly modelling tools working on the recent powerful computers. The main components of modelling include the conceptual model, the mathematical model and the graphical representation of hydrogeological system. In this study, a three-dimensional finite difference modelling program namely Visual MODFLOW was used for the study and prediction of aquifer system in a drought prone study area. The base map of the study area, various layers of the geological strata and their geological properties, boundary conditions, well data and recharge conditions were fed in to the model as inputs. The model was then calibrated and validated, after which future groundwater conditions were predicted.
