This 3-day hands-on course presents an introduction to environmental data management and analysis using HGA. Data management begins with the development of a database that integrates the variety of sources of environmental data that are common in hydrogeologic analysis. The data are then interpolated and mapped in HGA to generate the conceptual hydrogeologic model of the study area, which can then be used in site characterization, regional hydrogeologic analysis, compliance monitoring, and groundwater model development.
