| Zusammenfassung |
| The water balance and phosphorus inputs of surface waters of the Weiße
Elster catchment, Germany, have been quantified using the models
GROWA/MEPhos and SWAT. A comparison of the model results shows small
differences in the mean long-term total runoff for the entire study area.
All relevant pathways of phosphorus transport were considered in MEPhos with
phosphorus inputs resulting to about 65% from point sources. SWAT focuses
on agricultural areas and estimates a phosphorus input of about 60%
through erosion. The mean annual phosphorus input from erosion calculated
with SWAT is six times higher than the estimation with MEPhos due to the
differing model concepts. This shows the uncertainty contributed by the
modelling description of phosphorus pathways. |
