EarthVision® (EV) is a proprietary, integrated software system produced and 
distributed by Dynamic Graphics Inc.  EV is specifically to synthesize a wide 
variety of geo-spatial data into comprehensive conceptual models through which 
data can be visually and quantitatively analyzed through either deterministic or 
geo-statistical interpolation schemes. The strength of using EV lies in its unique 
ability to describe the geologic framework of a site and then incorporate parameter 
data, such as contaminant concentrations and permeabilities and engineering data 
such as borehole and tunnel orientations into the geologic framework. The 
fundamental utility of an EV model is the accessibility to data and interpretations it 
provides to a wide variety of users.

Our groundwater modeling tool of choice is the Finite Element Subsurface Flow 
System (FEFLOW), produced by WASY. FEFLOW is an interactive, graphics-
based groundwater modeling system for three-dimensional (3D) and two-
dimensional (2D) areal and cross-sectional (horizontal, vertical or axisymmetric), 
fluid density-coupled, thermohaline, or uncoupled, variably-saturated, transient 
flow, and chemical species and heat transport, with or without free surfaces. As 
a Computer Aided Engineering (CAE) oriented software package, FEFLOW is one 
of the most sophisticated simulation systems available.

The Groundwater Modeling System (GMS), developed for the U.S. Department 
of Defense, consists of a comprehensive graphical user interface (pre- and post-) 
and several groundwater flow and fate and transport simulation codes including 
MODFLOW, MT3D, RT3D, MODPATH, SEEP2D, and FEMWATER. 

Hazlett-Kincaid uses GMS whenever project considerations make it appropriate 
to use the MODFLOW, MT3D, and/or RT3D simulation codes for the groundwater 
flow and/or fate and transport components of a Hydrogeologic Site Model and in 
cases where relatively simple subsurface geologic conditions exist.

Hazlett-Kincaid utilizes Geographic Information Systems (GIS) technologies to process input data into our geologic and hydrologic modeling environments and to render highly usable deliverables from the various model outputs for our clients.  We are currently using ArcGIS 8.2, which is the most recent release of ESRI's GIS software that has combined the sophisticated functionality and graphic rendering of their previous software products, ArcInfo and ArcView.
