    DISCUSSION AND EXAM QUESTIONS

    1. Briefly describe the purpose and content of each of the five key modules of an SDSS.

    2. Discuss the qualifications you think would be needed by individuals hired in each of the five functional roles discussed in this unit.

    3. What kinds of analytical models might be included in an SDSS generator for each of the following applications:

    monitoring of ground-water quality; emergency evacuation from around nuclear power stations; monitoring and fighting forest fires? Are there any similarities in these models?
