| Zusammenfassung |
| The objective of this study was to assess the utility of the
eco-hydrological SWAT model (Soil and Water Assessment Tool, Arnold et al.,
1998) for representing water balance and nitrate fluxes given limited input
and calibration data. The investigated catchment is located in Western
Ukraine with an area of approximately 2616 km2. Land use is currently
dominated by agriculture with significant areas of pasture, and has
undergone a high degree of changes in land-use and agricultural practice
since the end of the Soviet Union. Model application produced a fitted water
balance (calibration: R2 = 0.52, NS = 0.46; validation: R2 = 0.47,
NS = 0.51) and plausible ranges and dynamics of nitrate in stream loadings.
Groundwater parameters were found to be highly sensitive. The results
indicate that SWAT is an appropriate tool for water resource investigations
in the Western Bug catchment, and can provide a useful tool for further
eco-hydrologic research in the region (i.e. diffuse pollution impacts). |
