The use of multiple tools in TACTIC pilots

The work in the TACTIC pilots are now well under way, and several partners are using more than one tool for climate change assessment in the same pilot area. This gives valuable information on the uncertainties of the assessments preformed with these tools as their responses can be compared and evaluated across each other. Furthermore, in order to test the applicability of the tool(s) under different hydrological settings, two tools types, a time series analysis tool and a lumped hydrological catchment model, will be applied across all (multiple tool) pilots.

The results from these investigations will, among others, be used in the development of the TACTIC guidelines and best practice protocols, one of the goals of TACTIC, on how to select the appropriate tools and approaches, given specific challenges and data availability for use in future assessments.
