The identification of boundary conditions for DOC turnover in soil and water under Russian climate conditions, especially in winter, and the resulting differences in DOC sources and pathways into the surface water bodies is of high importance to understand the critical DOC load in surface water of Russia and the related problems in drinking water supply.
A scale overlapping approach is designed which is based on catchment monitoring and is extended with further methods. Thus,
i) lysimeters will allow general characterisation of DOC leaching and DOC forms,
ii) experimental plots are utilised to quantify soil water and DOC fluxes and
iii) the model system IWAN will be modified to evaluate potential measures to reduce the DOC input into surface waters.
The aspired link of the anticipated results with practical implementation and demonstration in a Russian research catchment in co-operation with local stakeholders and KMU will be a substantial delivery to obtain the water quality in the Volga river basin.
