Application of the Bayesian calibration methodology for the parameter estimation in CoupModel (2009)
This study provides results for the optimization strategy of highly parameterized models, especially with a high number of unknown input parameters and joint problems in terms of sufficient parameter...
SEPAL – a simple GIS-based tool to estimate sediment pathways in lowland catchments (2009)
J. Kiesel, B. Schmalz, N. Fohrer
Even though soil loss in the lowlands imposes not as much a restriction on land use and agricultural productivity as in erosion affected mountainous areas, the input of fine sediment into the rivers...

The aims of this study are to identify the capacities of applying an ecohydrological model for simulating flow and to assess the impact of point and non-point source pollution on nitrate loads in a...
SRTM DEM levels over papyrus swamp vegetation – a correction approach (2009)
G. Petersen, I. Lebed, N. Fohrer
The SRTM DEM, a digital elevation model based on the Shuttle Radar Topography Mission of February 2000 is a source of elevation data with nearly worldwide coverage. It has proven its usefulness in...
Comparing model sensitivities of different landscapes using the ecohydrological SWAT model (2009)
Lowland areas are characterised by specific properties, such as flat topography, low hydraulic gradients, shallow groundwater, and high potential for water retention in peatland and lakes. The...

Large-scale hydrological modelling has become increasingly wide-spread during the last decade. An annual workshop series on large-scale hydrological modelling has provided, since 1997, a forum to the...
N. Fohrer, H.-G. Frede
The risk assessment of future land use changes with respect to their ecological impact is still an unsolved problem. The implementation of sustainable land use and soil conservation concepts for...
Spatio-temporal water body and vegetation changes in the Nile swamps of southern Sudan (2007)
Petersen, G., Abeya, J. A., Fohrer, N.
An assessment to describe and quantify the extent of changes in the channel and lagoon system of the Sudd was carried out using Landsat satellite images of 1973, 1979, 1997 and 2002. Using supervised...
