Hydrological Impacts of Various Land Cover Types in the Context of Climate Change for Zala County

Hydrological Impacts of Various Land Cover Types in the Context of Climate Change for Zala County DOI: 10.2478/aslh-2014-0009 Acta Silv. Lign.

The highest mean ET rates were determined for water bodies (658 mm/year) and wetlands (622 mm/year).

Mean annual runoff is the largest on artificial surfaces (89 mm/year), and it decreases on the other land cover types. 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 ET and R in spatially-distributed http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Acta Silvatica et Lignaria Hungarica de Gruyter
