Climate change predictions give evidence for prolonged drought periods with increased risk of forest fires in Croatia and a redistribution of annual rainfall in the Austrian Alps. Under both climatic conditions, soil water repellency is expected to increase as a result of prolonged soil drying. Since now, soil water repellency is not accounted for in soil hydrological models. The objective of this bilateral project is therefore to apply scaling methods to implementing variable soil water repellency levels in a soil water model. Field and laboratory experiments will be performed for selected study sites in both countries. Infiltration experiments with water and ethanol will serve for model calibration. Climate change scenarios will be used to assess the expected impact of
increased water repellency on local and regional hydrology.
