Generic collaborative management tools


The generic collaborative management tool ‘REACHER’ was developed to be used by stakeholders, citizens or water managers to evaluate the ecological and economic effects of different remedial actions on water bodies. The tool consists of four major parts:

  1. fate models to integrate the fluxes of chemicals at the river basin scale;
  2. an assessment of the ecological effects of chemicals in river basins;
  3. an economic analysis of the rehabilitation technologies (costs and benefits); and
  4. the integration of fate, effects assessment and economic analysis tools into a collaborative management tool or DSS REACH-ER with a users’ interface.

The prototype tool covers a river basin scale with the Scheldt River Basin and the Odense River Basin as examples, focussing mainly on surface water.



The second prototype REACHER-local focuses on groundwater at a regional scale.µ Users are able to explore:

  1. the status of polluted sites across a region;
  2. how the status evolves in time with/without remediation;
  3. which potential impacts can be expected for different sites;
  4. which societal costs we would be expected to bear due to the environmental damage;
  5. which societal benefits that can be achieved by reducing pollution levels; and,
  6. which technologies can be implemented for different sites and score best in terms of costs and effectiveness (speed).

The REACHER and REACHER–local software are open. Geo-referenced data on specific contamination sites are protected and fall under confidentiality agreements with the data providers. Public data, however, can be obtained by a specific data request to the public authorities
