- Abstract
- The groundwater resource is crucial for water supply, irrigation and urbanization. Accurate assessment of recharge and prediction of future groundwater levels in groundwater system is vital for water management in a particular area. Recharge, as an input to groundwater model, is usually some fraction of rainfall. However, recharge is affected by spatial and time varying events on the surface. The present study demonstrates use of Arc SWAT model for water surface simulation and the estimation of recharge rates. The recharge values estimated using Arc-SWAT model are inputs to Visual MODFLOW groundwater system simulation model, parametric sensitivity analysis with hydraulic conductivity value performed. Calibrated and validated model further employee for future groundwater levels predictions in potential groundwater management scenarios. Methodology employed in Sai-Gomti interfluve region in India.
