Analysing the Krycklan water quality data using a landscape systems approach

PI: Gunnar Lischeid

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.

DRIP effect on organic matter decomposition

PI: Lenka Kuglerova

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.

Protecting water quality hotspots along streams

PI: Stefan Ploum

This project aims to characterize the hydrological and biogeochemical dynamics of riparian contributions to boreal streams. We use thermal and chemical tracing to capture these dynamics, in particular during high flow events.
