This CD-ROM puts users in the role of a practicing geologist -- gathering and analyzing real data, evaluating risk, and making assessments and recommendations. Based on the idealized town of Hazard City, this dual-platform CD contains a collection of eight interactive problem-solving activities corresponding to key issues faced by environmental professionals. Covers many issues of importance to environmental professionals such as ground water contamination, volcanic hazard assessment, landslide hazard assessment, earthquake damage assessment, flood insurance rate maps, snowpack monitoring, coal property evaluation, and landfill siting.
