All natural waters contain organic matter in the form of Dissolved Organic Matter (DOM) The dissolved organic matter (DOM) affects a suite of processes in surface water and soils because it provides energy and nutrients for the biota and it affects the bioavailability of trace metals and organic pollutants. In addition, DOM plays a role as electron donor in denitrification in riparian zones, and leads to the formation of unwanted disinfection byproducts
in drinking water production.
DOM can be transported to surface water by surface flow, subsurface flow, and baseflow, The fate of DOM differs along these flow paths, and the hydrology of a catchment thus affects the concentration and composition of the DOM that reaches the surface waters. To assess the relative importance of flow paths for transport for DOM from soil to surface water, DOM transport processes will be monitored in two areas with very distinct soilscapes: one set of
measurements will be conducted in a 117-ha agricultural catchment in the erosion-prone siltloam belt in central Belgium. Another set of observations will be made in a small (10-50 ha) headwater catchment (Rollesbroich catchment, mainly grassland) in the Eifel region near Aachen, Germany. Research at the second field site will be carried out in close collaboration with the Agrosphere Institute at the Forschungszentrum Jülich, Germany.
To model DOM fluxes and pathways from the soil to surface water, the candidate will build on modelling approaches that describe surface run-off and 3-D water flow in the saturated and unsaturated zone of small catchments.
