Abstract
In the first part of this lecture, we discuss the effect of pedotransfer functions (PTFs) on spatial patterns of runoff generation processes. In the second part, we demonstrate plant parameter calibration based on MODIS time series and the effect of on spatial pattern of Evapotranspiration.
 
PTFs are the central tool to transfer the physical properties of the soil into model parameters. We demonstrate that the selection of the PTF has a large impact on model behavior, e.g. the spatial distribution of runoff generation processes within a catchment.
 
Remote sensing plays a central role in improving model parameterization and model evaluation. We used an 11-year MODIS time series of ETa (8-day-sum) to calibrate different parameters of the Penman-Monteith approach. Based on single-day LANDSAT ETa datasets, we can demonstrate the improved spatial and temporal performance of our model.
Bio
Markus Casper studied Geoecology at Karlsruhe University/Germany (now known as Karlsruhe Institute of Technology). He earned his Ph.D. (Dr.-Ing.) in Hydrology from the same university in 2002, with a thesis in the "identification runoff generation process in the Northern Black Forest area." Afterward, he worked as a scientific project coordinator in an EU-funded project on the simulation of nitrate in the groundwater of the Upper Rhine Valley. In December 2003, he joined the University of Trier as an Assistant Professor of Physical Geography. His primary research focuses on the question of how closely our hydrological simulations align with reality.
