This project follows and quantifies waterborne pollutant transport from sources to downstream loads, assessing the mitigation opportunities provided by wetlands in the landscape, through current to future hydroclimatic conditions across different hydrological basins and catchments. Main research questions of the project can be summarized as:

- What cause-effect relations determine spatiotemporal pollutant load variability and change across different scales, regions and hydroclimatic and wetland conditions?

- What future scenarios of waterborne pollutant loads are plausible, and what are the opportunities for wetlands and wetland networks in the landscape to reduce them and safeguard good water quality and ecosystem status?

As a consistent comparative basis across different site conditions, the project focuses on heavy metal transport, and will develop relevant data compilations, methods and tools across different Swedish investigation drainage basins/catchments and international comparative studies through the international network GWEN - Global Wetland Ecohydrology Network: An Agora for Scientists and Study Sites. The project includes own field and model investigations of the particularly large Lake Baikal Drainage Basin in Russia, with wetland focus on its Selenga River delta.

The project is funded from The Swedish Research Council Formas (grant number 2012-790).
