Work Package 8: : Case-studies and user validation

The overall objective of WP8 is to validate on the user point of view the LENVIS platform in three case studies, according to a pre-defined evaluation plan.

The case studies are located in three of the countries of the project, Italy, Portugal and The Netherlands. The aim of case studies is to validate from the user point of view the lenvis platform. The objective of the case study in Italy is to demonstrate the integration between integrated air quality management in Bari and integrated health services for the city of Milan, by analysing the relationship between air pollution and health risks. The objective of the case study in Portugal is to develop an alert system for beach recreational water quality. The objective of the case study in The Netherlands is to develop citizen-oriented monitoring and forecasting of the air quality, water quantity and health risk assessment in the Province of Noord Brabant.


The objective for the case study in Italy is to use air quality monitoring and prediction and health services for the urban areas of Milan and Bari to analyse relationships between air pollution and health risks to evaluate air quality management strategies for their effectiveness and to forecast air quality conditions and probable effect on health, to provide warnings to the public. The two test sites are quite different in their climate and in their prevalent economy, which makes Milan the optimal test site for traffic-related pollution analysis and Bari the optimal test site for ozone pollution studies.

The Portuguese case study addresses bathing water quality and related health issues. Thus, three bathing waters nearby Lisbon - Carcavelos, Torre and Santo Amaro de Oeiras - were chosen to locally implement and validate lenvis. The main goal for this local case study is to narrow the gap between beachgoers, public authorities (local and national) and professionals that have responsibilities or competence over the bathing water quality of these beaches.

For the case study in the Netherlands citizen oriented, continuous monitoring and forecasting systems for air quality, water quality and related health risk assessments in the Province of Noord-Brabant will be developed. The citizens will be able to access the real-time data and forecasts on demand and through the same lenvis platform they can actively report own observations. This is in line with the current efforts from the Province Noord-Brabant to have more involvement from and with their citizens.

Data and process flow for the Forecast case studies


With the case studies defined in detail development of the lenvis services has been started. Real-time data streams are running, and first modelling services for air quality have been established. A water quality model, with interactive data updates, for the Binnen lake, in the Province of Noord Brabant, has been developed as well. In 2010 several demonstration activities to end-users are foreseen to establish an interactive development of the lenvis platform. In the summer of 2010 first end-user testing and validation activities were carried out in the summer of 2010, and will be continued in summer of 2011.
