This study proposes a transient groundwater modeling using spreadsheet simulation (TGMSS) model for solving groundwater problems. TGMSS may be considered as a practical method and introduction to groundwater modeling that uses spreadsheets instead of conventional groundwater model codes. Irregular aquifer geometry, variable boundary conditions and sinks and/or source values, heterogeneous aquif...

The MODFLOW Lake Package is integrated into the FREEWAT GIS environment in order to simulate surface water groundwater interaction using state of the art techniques for numerical simulations, thus allowing the improved consideration of surface water bodies for water resources management. Surface water bodies, both stationary and flowing, can strongly affect groundwater elevations and flow patte...

The aim of the study was to evaluate water quality impact caused due operations common hazardous waste landfill facility (CHWLF) in Gummidipoondi industrial estate, Tiruvallur district, Tamilnadu, India. watershed area delineated using Arc-GIS tools and prediction ground flow direction carried out three-dimensional model VISUAL MODFLOW software. analysis performed upstream downstream directions...

This paper presents the program KALMOD which has been developed to enable the execution of the integration of the Kalman filtering and the numerical groundwater flow model MODFLOW on microcomputers. The program can be applied to quantify and reduce the uncertainty of the groundwater flow model, and to analyse and design groundwater monitoring networks. KALMOD consists of a preprocessor, a proce...

We present a new three-dimensional steady-state saturated groundwater-flow forward-simulator with full conductivity tensors using a nineteen-points block-centered finite-difference method. Hydraulic conductivity tensors are defined at the block interfaces eliminating the need to average conductivity tensors at adjacent blocks to approximate their values at the interfaces. The capabilities of th...

Surface water flow and subsurface have traditionally been investigated separately simulators developed over the years, to model each of these systems. Growing interest in conjunctive management, need for simulations surface/subsurface their interactions has lead linking models respective domains. This study from Dharoi command area, using MODFLOW, showed pertaining second layer calibrated model...
