Bio:

I graduated from the University of Ghent (Belgium) in Agricultural Engineering in 1985 where I also obtained an M.Sc. in Control Systems Engineering in 1989. Meanwhile I worked as a research and teaching assistant at the Laboratory of Hydrology and Water Management and the Seminar for Applied Mathematics. From January to August 1992, I visited the Water Resources Program of Princeton University and assisted Dr. E.F. Wood in developing remote sensing applications in hydrological modeling. In 1993 I completed my Ph.D. dissertation in Hydrology, "Conceptual Basinscale Runoff Process Models for Humid Catchments: Analysis, Synthesis and Applications."

I was appointed Assistant Professor (1993) and Associate Professor (1996) in the Department of Forest and Water Management at the University of Ghent. In 1999 I moved to the Netherlands to become Full Professor of Hydrology and Quantitative Water Management at Wageningen University, and in November 2005 I joined the UA Department of Hydrology and Water Resources. I was Associate Editor for Water Resources Research from 1999 to 2005, and I am member of the editorial board of Advances in Water Resources.

Research Areas of Interest:

My research aims at a better understanding of catchment scale hydrological processes through advanced measurement, modeling and synthesis methods. My objectives are:

  • Developing, testing and applying advanced observation methods for hydrological fluxes and states at a range of spatial and temporal scales
  • Developing hillslope to catchment scale hydrological models for water and solute transport
  • Hydrological synthesis at the catchment scale with special attention to hydrological extremes

The motivation is to contribute to improved water resources management in the light of climate change and other human influences on the hydrological cycle.

I established the Surface Water Hydrology Group in the Department of Hydrology and Water Resources in November 2005. We are involved in a wide range of research topics related to hillslope, catchment and river basin hydrology. Much of our work focuses on understanding hillslope to catchment-scale characteristics such as flow pathways, water residence times, and rainfall-runoff relationships in complex terrain.

In addition, we focus on issues of water availability and management at the river basin scale. We are currently maintaining and collecting data from field sites in the Santa Catalina Mountains near Tucson, AZ and in the Valles Caldera Nature Preserve near Los Alamos, NM, however some of our research also focuses on areas as large as the Colorado River Basin. The primary mission of the group is to provide cutting-edge solutions to problems in surface water hydrology.
