The project aims to increase the understanding of hydrological processes and transport in the surface and subsurface system under different climate conditions. We aim to develop a coupled hydrological-biogeochemical transport model that we can use to investigate different sites under different climate conditions. A coupled model describing solute transport at a landscape level will provide valuable information to the development of biosphere models. The impact on transport and biogeochemical processes in the landscape caused by differences in hydrology and climate are vital to get a better understanding of, especially when conceptualizing the ecosystem models used for radionuclide transport and dos-calculations. Nevertheless, the understanding of how and if a conceptual model of an eco-system needs to be changed in different climate scenarios is limited. One aim of this project is to identify conceptual differences in transport and accumulation of matter within and between eco-system under changing climate states.

Decades of extensive research in the Krycklan Catchment have unravelled a multitude of hydrological, biogeochemical and biological processes. Whereas clear evidence can be found in the lab or in plot scale studies, a proof of relevance at the landscape scale requires powerful modern methods. To that end two different approaches (Isometric Feature Mapping and Self-Organizing Maps, combined with Sammon's Mapping) are applied to a comprehensive stream and groundwater quality data set.

In this project we are looking on how do DRIPs (discrete riparian inflow points) affect decomposition of organic matter. We are using standardized assays of tea-bags and cotton strips to asses decomposition patters in riparian soils and in streams. 30 sites with a gradient of DRIP magnitude (from relatively dry sties to zero order stream channels) are used along streams C5-C6, C4, C8, C7, C10, C3, C1 (plus potential additions). The project is a collaboration with Umeå University and Griffith University, Australia.

I want to investigate different aspects of hydrologic connectivity in the boreal landscape. The project includes field measurements as well as a modelling approach to identify, quantify and analyse key aspects of hydrologic connectivity.
