Dear Iquebal HossainThanks for raising such an emerging issue on this network. I know the Barind region of Bangladesh heavily relies on GW (groundwater) irrigation; therefore, a sharp declining in GWL (groundwater level) has been reported in many documents.I think before thinking about artificial recharge, a pilot study may be conducted to understand the actual GW dynamics of the region. At least two sites can be selected for the study: (i) one site would be where GW shows less fluctuation and (ii) another site would be where high GW fluctuation is evident. This may be achieved by analysing observed GWL data. Later, a physics-based GW modelling study may be conducted to understand the real local GW dynamics. This approach would requires reliable field data. I think such an experiment can explore the potentiality of GW recharge or other undiscovered facts. So far I know in Bangladesh such a sophisticated research work has yet to be done. Thanks.Mizan
