Peter A. Troch
Professor of Hydrology and Water Resources and heads the Surface Water Hydrology group of the Department of Hydrology and Water Resources, University of Arizona
Univ. of Arizona - University of Arizona
PhD, University of Ghent, Belgium, 1993
His research aims at a better understanding of catchment scale hydrological processes through advanced measurement, modeling and synthesis methods. The objectives are: (i) Developing, testing and applying advanced observation methods for hydrological fluxes and states at a range of spatial and temporal scales, (ii) Developing hillslope to catchment scale hydrological models for water and solute transport, and (iii) Hydrological synthesis at the catchment scale with special attention to hydrological extremes.
