Academic Interests

  • Hydrological modelling, with emphasis on distributed modelling and improved representation of processes in global change studies;
  • Regional low flow and drought analyses, including extreme value analysis and space-time characteristics of drought at the catchment, regional and continental scale;
  • Hydroclimatology, addressing the main climate drivers of drought;
  • Global change impacts, including land use and climate change on water resources and hydrological extremes.


Higher education and employment history

Scientific engagement involves cooperation with a wide range of institutions and researchers, through national and international research projects and networks. Activities include:

  • EU-funded WATCH project; with 25 European partners
  • NFR project SoCoCA
  • NUFU project “Water Sciences”; with partners from southern Africa;
  • UNESCO FRIEND Project; with participants from Europe and globally,
  • COST733 action; with participants from most European countries
  • The European Drought Centre; with members from Europe and beyond;
    Long-term international collaborations include the Wageningen University (the Netherlands), the University of Birmingham (UK), and Freiburg University (Germany). National research relations exist with the Norwegian Water Resources and Energy Directorate (NVE), SINTEF and Statkraft.


Received in 1998 the International Association of Hydrological Sciences ‘Tison Award’ for the article; On the definition and modelling of streamflow drought duration and deficit volume. Hydrol. Sci. J., 42(1).
