The specific objectives of the project are:    
    
  To establish hydrological and water quality databases for a range of key European ecosystems;     
  To apply the process-based dynamic model, INCA, to these selected catchments across Europe;     
  To establish nitrogen budgets in the catchments and compute fluxes of nitrogen on a daily, seasonal and annual basis both for the plant/soil system and in 
stream;     
  To establish nitrogen budgets in the catchments and compute fluxes of nitrogen on a daily, seasonal and annual basis both for the plant/soil system and in 
stream;     
  To modify the model process equations as necessary to ensure a generic model applicable to a wide range of ecosystems and catchments;     
  To use the model to assess the impacts of land use change, climatic change, atmospheric deposition change and agricultural change in the selected catchments; 
    
  To compute fluxes of nitrous oxide gas release from catchments, riparian zones, wetlands and stream beds;     
  To investigate model parameter and structural uncertainty and scale-up from the plot scale to the small catchment scale and through to the large catchment 
scale;     
  To add an economic component to INCA to assess costs and benefits of nitrogen controls in European catchments;     
  To create an easy to use Windows version of INCA with high quality graphics for management and scientific use;     
  To make INCA available to the European Environment Agency, National Environment Agencies, the Water Industry and other interested parties;     
  To publish the findings in referenced international journals and produce material such as glossy brochures for wider distribution to the general public. 
            

The INCA project is based on the INCA (Integrated Nitrogen in Catchments) model, a processed based representation of plant/soil system and instream nitrogen 
dynamics. The INCA project aims to use the model to assess the nitrogen dynamics in key European ecosystems.   
   
The work  involved the investigation of the likely impacts of environmental change on streamwater N concentrations and loads, both in the individual ecosystems 
and at the pan European scale.
