In this study, a two layered finite difference method has been generated for groundwater flow analysis of Ghataprabha sub-basin of Krishna river basin. The conceptual model has been calibrated for steady state conditions and validated for both steady state and transient conditions through USGS, 3D Finite Difference Code and MODFLOW. Various applications were tried out on the calibrated model, like River-Drain influencing the aquifer, reasons for waterlogging and drying out of wells and well design strategies.
The flow model has been generated to look at the interaction between Ghataprabha river and the conceptualized Ghataprabha basin aquifer. The generated mesh allows trails for many other options for boundary conditions all along the Ghataprabha sub-basin boundary. The boundary condition used here is the surface water hydrological boundary and was found to work well. Though the steady state condition results are only a conceptualized condition and may not exist at any time step but it has enormous importance as a hydrostatic condition while designing water development activities. This model is useful for groundwater development in Ghataprabha sub-basin in Krishna river basin.
