Modeling of Groundwater Levels in the Sonar sub-basin, Madhya Pradesh Using Visual MODFLOW

The study of groundwater levels in unconfined aquifer is very useful for water resources planning and management. Aquifers in different regions of the Madhya Pradesh, India experienced significant groundwater decline during the last decade due to excessive ground water withdrawal. The aquifer located in the alluvial plains of Madhya Pradesh is prominent source of groundwater. The fluctuation in these aquifers raised concerns over the quantity of groundwater, as well as concerns over the planning and management policies used in Madhya Pradesh. This study was conducted with an objective to study groundwater levels fluctuation and to estimate the annual change in groundwater levels of Sonar sub-basin located at Madhya Pradesh. The numerical groundwater model (Visual MODFLOW) was used for this study. The results obtained from the model were found to be in agreement with the observed records. Moreover the simulation results indicated reasonable declination of groundwater levels during the study period.
