You are here: / Practice / Tools / The impact analysis of alternatives

After the investigation and definition phase, a number of (perhaps new) planning alternatives are listed and investigated. Impacts of alternatives can be investigated from a detailed (local) scale to a larger (river basin) scale. Examples are:

  • STREAM (tool for river basin impact analysis) (link to explanation stream)
  • DR-EIA (Document Retrieval and expert system for Environmental Impact Assessment
  • MMARIE (modelling of marine ecosystems)

Figure 3-2 STREAM helps you to compare impacts, of for example climate change, on your river basin
