- Abstract
Of all mountainous regions in the world, the network of precipitation stations is the densest in the Alps. Nevertheless, the precipitation regime at the micro level continues to be poorly known at many a place. Most of the precipitation stations in mountain landscapes are located at lower elevations and in settled areas, while they are rather few at higher elevations. Moreover, the accuracy of measurements in the mountains is problematic and therefore the information on precipitation regime is deficient exactly in the wettest areas. The water balance estimation is incorrect, and it is difficult to forecast precipitationrelated hazards, such as torrential floods, landslides, avalanches, and the like. The paper discusses the horizontal precipitation gradients in the Alpine valleys of Planica, Krnica and Beli Potok which are all situated in the north-western part of the Julian Alps in Slovenia. At the annual level of the studied period the following values were reached: 162 mm/ km at Krnica, 192 mm/km at Beli Potok and 216 mm/km at Planica, and these belong to the highest gradients in Slovenia. In comparison with the lowest points of the researched valleys, the precipitation amount in their uppermost parts increases by the factor of 1.36 at Beli Potok, 1.55 at Krnica and as much as 1.86 at Planica.
