Work package 5

Leader: Isabel Seifert-Dähnn (NIVA)


This WP will use a cost-benefit approach to contrast the costs for the installation, maintenance and continuous usage of a HF lake monitoring and forecasting system with the benefits derived from it. Our focus is on the benefits for drinking water provision and recreational use. We will follow the best-practice approach suggested by the European Commission for cost-benefit assessment of investment projects. Drinking water treatment plants will be evaluated to assess their ability for further exploiting already existing monitoring data by processing it into lake water quality forecasts. The work is divided into two main tasks:

  • WT5.1 Cost data for HF monitoring and modelling will be gathered from ongoing monitoring activities at demonstration sites, reflecting the range of technologies used (buoys, fixed monitoring installations, data transmission and handling, forecasting software, dissemination, etc.). Even though not all case-study lakes are used for recreational purposes or as drinking water sources, it is possible to deduce cost estimates from them, and apply to similar relevant cases. If necessary, the work will be supplemented by available literature data.
  • WT5.2 To assess the benefits of HF monitoring and of water quality forecasting for recreational purposes, we propose to apply a benefit-transfer approach. This approach does not require new data; it instead uses data from existing surveys on recreation and water quality available at our respective institutes and in the literature. Benefits for drinking water provision will be determined together with the end-users involved in the project.
