| Zusammenfassung |
| The Zala River provides the largest inflow of water to the Lake Balaton, which is the biggest
lake in Central Europe. Water balance of the catchment of Zala River was analysed using
remote-sensing based evapotranspiration maps (1 km2 spatial resolution) for Hungary over
the 2000-2008 period.
For climate change impact analysis a Budyko-model was used in spatially-distributed
mode. The parameter of the Budyko-model (α) was calculated for pixels without surplus
water. For the extra-water affected pixels a linear model with β-parameter (actual
evapotranspiration / pan-evapotranspiration) was used. These parameters (α and β) can be
used for evaluating future evapotranspiration and runoff in spatially-distributed mode. α and
β parameters were validated for the Zala catchment using historical precipitation and
streamflow measurements.
By using the two parameter maps and future data of climate models (mean annual
temperature and precipitation) evapotranspiration and runoff predictions have been done for
three periods (2011-2040, 2041-2070, 2071-2100).
This research has been supported by AGRARKLIMA.2 VKSZ_12-1-2013-0034 project. |
