Description

The aim of this project is to contribute towards the understanding of water chemistry variations at the landscape scale. Previous work has indicated that the hydrological processes in the riparian zone might hold the key to understanding much of the spatial and temporal variation in water chemistry at the landscape scale. Therefore, the focus of this project is on the functioning of the riparian zone. The project will develop and refine hydrological landscape analysis techniques to bridge between small-scale understanding and catchment-scale water quality issues. By designing a riparian observatory we will test a hypothesis of how the riparian zone of till catchments influences the flow-related dynamics of water chemistry as exemplified by DOC. The informed sampling of the riparian zone hydrology and hydrochemistry will be of great value to a research community that is increasingly looking to the RZ for explanations of how catchment changes are linked to water quality. We then will formulate the simplest set of conceptual model routines that adequately describe hydrological conditions and their impact on the flow of DOC from the riparian zone and other dominant landscape units in boreal catchments. The project will also improve our ability to predict how human influence, including climate change will effect forested boreal waters where DOC is a key chemical constituent.
