Ph.D. thesis
Flux-based risk assessment of the impact of contaminants on water resources and ecosystems
Promoter: Prof. dr. Okke Batelaan (HYDR)
Co-Promoter: Prof. dr. Frank Canters
This research is part of the FRAC-WECO project which is carried out in collaboration with the University of Liège, the Vlaamse Instelling voor Technologisch Onderzoek (Vito) and the Bureau de Recherches Géologiques et Minières (Orléans, France). The objective of the project is to describe the state, i.e. the dynamics of the ‘water-soil-subsoil-sediment’ system and, more in particular, to define models to accurately assess the water and contaminant mass-balance and fluxes at catchment scale for further downscaling at the level of specific contaminated sites. The Ph.D. work focuses on the use of remote sensing data in high-resolution surface water budgeting, in particular ground water recharge modeling and run-off routing. Specific attention will be paid to the impact of image classification uncertainty on model output.
The research consists of 3 major parts:
- high-resolution land-cover mapping based on remotely sensed data. The mapping will be accomplished for different
periods of the same year, so that water fluxes can be analysed in a multi-temporal way.
- budgeting of spatially distributed surface water.
- assessing the impact of land-cover classification uncertainty on model results.
