Annual Progress Report CLEO 2013 Project 3.2 Linking processes and scales in geochemical and hydrological models Project leader: Göran Lindström, SMHI, email@example.com General Objective: To increase understanding of soil-water processes in a changing environment, as a tool for improved up-scaling in water quality models. Short description of activities 2013: Project 3.2 is scheduled as a minor activity during 2013 in the CLEO work plan. Work has focused on further development of the HYPE model and S-HYPE set-up, and article writing. The S-HYPE simulations and NET modelling in CLEO will be based on a new S-HYPE version finalised in 2013. The new S-HYPE version has improved lake depth information and improved modelling of storm water drainage, among other things. Deliverables 2013: A first NET model version was developed in December. It uses the same data base and spatial resolution as the S-HYPE model. Additional staff involved in project: Staff at IVL, SLU and SMHI. Co-operation outside CLEO: Water framework directive work at SMHI etc. Reports and publications: A paper “Dynamical modelling of discharge and water quality for small boreal forested catchments” is in progress. Oral presentations: IAHS Conference Göteborg: presentation on temperature effects on water quality modelling with the HYPE model, by René Capell.
