Sažetak
Prolonged drought periods with increased risk of forest fires or a redistribution of rainfall may increase soil water repellency (SWR), affecting soil hydrology and solute transport processes in soil. In the Austrian Alps, prolonged dry periods may cause a re-orientation of the organic molecules on solid surfaces and increased SWR. In Mediterranean environments such as the Croatian coast, frequently occurring forest fires may also have an impact on SWR due to heating of organic soil matter. This work is a part of Croatian Austrian bilateral project focused on SWR effect on soil hydraulic properties. The field site is set up in Rosalia forest demonstration center (Austria) with three climate change scenarios: moderate, extreme and natural rainfall (control). In Croatia the test site is located near Šibenik with three treatments in relation to fire occurrence: heavily affected, affected and non-affected (control). On both sites water and ethanol infiltration measurements were performed. First results indicate strongly reduced infiltration of water compared to ethanol at both test sites i.e. high degree of SWR. This could cause a change in soil hydraulic properties of the same soil type. Due to changed SWR, local scale hydrology and consequently transport processes in soil could be affected.
