HYDRAULIC CONDUCTIVITY OF THE SOIL SURFACE AND MAXIMUM RAINFALL INTENSITIES IN FOOTHILL PART OF JALOVECKÝ CREEK CATCHMENT. We measured hydraulic condictivity of soils (kf) in the foothill part of the Jalovecký creek catchment at 22 sites using the minidisk permeameter and suction –2 cm. Seven measurements of kf were conducted at each site (area about 1 m2). Geophysical measurements (electromagnetic conductivity) were performed at each site to assess the homogeneity of soil conditions at two effective depths of 35 and 70 cm. The sites were selected according to gemorphological and geological properties. They covered soils developed at deluvial sediments, glaciofluvial sediments, river terraces and flysh. The results showed a rather high variability of kf between different regions, within regions and also at individual sites. Just values measured on clay loams exhibited relatively smaller variability. Maximum 10-minutes and hourly rainfall intensities were analysed at two stations. Comaprison of rainfall intensisties with hydraulic conductivities of soils confirmed that conditions for generation of Hortonian overland flow are met only rarely and at just a few sites.
