1. Mobile phosphorus in lake sediments, sludge and soil : A catchment perspective
Abstract : Phosphorus (P), a key element in lake primary production and eutrophication, is accumulating in agricultural soil, urban landfills and lake sediments. This accumulation increases the risk for non-point losses of P to ground- and surface waters. READ MORE

2. Seasonal variation and landscape regulation of dissolved organic carbon concentrations and character in Swedish boreal streams
Abstract : The seasonal variation and landscape regulation of dissolved organic carbon (DOC) concentrations in streams have been studied in two watersheds in the boreal zone. The seasonal variation was found to be highly correlated to variations in runoff. An increase in runoff was always accompanied with an increase in DOC concentration. READ MORE

3. Geographical Distribution of Disasters Caused by Natural Hazards in Data-scarce Areas : Methodological exploration on the Samala River catchment, Guatemala
Abstract : An increasing trend in both the number of disasters and affected people has been observed, especially during the second half of the 20th century. The physical, economic and social impact that natural hazards have had on a global scale has prompted an increasing interest of governments, international institutions and the academia. READ MORE

4. Spatiotemporal streamflow variability in a boreal landscape : Importance of landscape composition for catchment hydrological functioning
Abstract : The understanding of how different parts of a landscape contribute to streamflow by storing and releasing water has long been a central issue in hydrology. Knowledge about what controls streamflow dynamics across landscapes can further our understanding of how catchments store and release water, facilitate predictions for ungauged catchments, and improve the management of water quality and resources.

5. Quantifying pollutant spreading and the risk of water pollution in hydrological catchments : A solute travel time-based scenario approach
Abstract : The research presented in the thesis develops an approach for the estimation and mapping of pollutant spreading in catchments and the associated uncertainty and risk of pollution. The first step in the approach is the quantification and mapping of statistical and geographical distributions of advective solute travel times from pollutant input locations to downstream recipients.
