Modeling and Management Option Analysis for Saline Groundwater Drainage in a Deltaic Island

چکیده
Understanding the interactions between shallow saline groundwater and surface water is crucial for managing logging in deltaic islands. Water conditions result accumulation of salt root zone crops detrimentally affect agriculture economically socially backward region West Bengal Bangladesh. In this paper, we undertook a modeling study water–groundwater Gosaba Island Sundarbans Ganges delta using MODFLOW followed by comprehensive parameter sensitivity analysis. Further, scenario analyses (i.e., no-drain, single drain, three drains) were undertaken to evaluate effectiveness drainage infrastructure reduce conditions. The evaluation indicated that installation drains can remove at rate up −123.3 m3day−1 lower table 0.4 m. drain management could divert −77.9 during post monsoon season, lowering 0.1 This preliminary shows encouraging results consider as solve increasing challenge salinity region. insights will be useful farmers policymakers planning various sustainable management. Building potentially part initiatives like national employment guarantee scheme India. future, model coupled with solute transport models understanding current status future expansion area. Further optimization analysis help identify optimal depth spacing drains.
