Groundwater Modeling HydroQual's Groundwater Modeling Group consists of nationally-recognized, groundwater hydrogeologists, hydrologists, and groundwater modelers that complement the firm's international reputation and experience in surface water and sediment transport modeling. As with the surface water models, the application of numerical codes to the dynamic processes of groundwater flow and contaminant transport is both art and science. The "art" of modeling has been acquired through nearly 30 years of professional experience at scores of sites throughout the country and abroad. |

| Application
of State-of-the-Art Codes HydroQual employs a variety of computer model codes ranging from simple, analytical-based programs to state-of-the-art three-dimensional numerical codes such as MODFLOW and MT3D (multi-species). These models are supported with graphical-based pre-processors and GIS-based post-processors to enhance their functionality and facilitate data presentation through multi-color groundwater contours, isoconcentration maps, vector plots, particle tracking three-dimensional iso-surfaces, and animation. During the past decade, our groundwater modeling staff has developed over 40 site-specific groundwater models including ones that assess the effectiveness of landfill caps and perimeter walls to ones that predict the cleanup time for chlorinated solvents in complex fractured bedrock flow systems. Without exception, remedial systems, designed and constructed using these models as a basis, have performed consistent with the model predictions and have been successful at achieving their objectives. Our staff has also developed specialty modeling programs to simulate matrix diffusion of contaminants in fractured media, the migration of naturally-occuring tritium through fractured rock aquitards, and soil-vapor extraction systems. |
