Environmental Modeling Systems GMS, SMS and WMS, provide userfriendly, graphical user interfaces for industrystandard numerical models in groundwater, surfacewater, and watershed modeling applications. EMSI specializes in hydrogeologic modeling using the most comprehensive groundwater modeling and site analysis system: the GMS software. GMS provides tools for every phase of a groundwater simulation including site characterization, model development, calibration, postprocessing, and visualization. GMS supports both finitedifference and finiteelement models in 2D and 3D including MODFLOW 2000, MODPATH, MT3DMSRT3D, SEAM3D, ART3D, UTCHEM, FEMWATER, PEST, UCODE, MODAEM and SEEP2D. These models allow saturated and unsaturated flow modeling, contiminant transport and decy modeling, particle tracking, reactive transport modeling, NAPLDNAPL modeling, densitydependent modeling, analytical element modeling, 2D analytic modeling, seepage modeling, bioremediation modeling, stochastic modeling and risk assessment.
