Abstract: Visual MODFLOW is a software that combines industry-standard codes for groundwater flow and contaminant transport, essential analysis and calibration tools, and stunning 3D visualization capabilities in a single environment. It allows users to build models faster and more efficiently, handle large and complex data sets, and visualize model inputs and outputs in 2D, 3D and multi-view displays. Visual MODFLOW has been widely used for various applications such as delineating well capture zones, designing pumping well locations, determining contaminant fate and exposure pathways, simulating surface water-groundwater interactions, evaluating groundwater remediation systems, and assessing saltwater intrusion. This paper reviews some of the recent studies that have used Visual MODFLOW for groundwater flow and contaminant transport modeling in different settings and scenarios. The paper also discusses the advantages and limitations of Visual MODFLOW as a modeling tool, and provides some recommendations for future research and development. The paper aims to provide a comprehensive overview of Visual MODFLOW applications in groundwater modeling, and to highlight its potential for addressing complex hydrogeological problems.
