Sažetak
The Mediterranean karst region in the Republic of Croatia covers 15389 km2. This is the area of exceptional national value which has developed under specific natural conditions. This area contains about one million hectares of forests and forestland. Since the forest vegetation is severely devastated and sparse, its hydrological function is seriously reduced. The objective of the study was to determine the influence of the precipitation regime and type of forest on soil erosion, runoff and total nitrate discharge into stream. Field monitoring for continuous measurements of rainfall, soil erosion, runoff and atmospheric deposition was conducted in the black pine forest near Split (SE of Croatia). Atmospheric deposition was measured as a bulk open field deposition in the vicinity of the plot and throughfall deposition below the forest canopy. Soil erosion plots, 50m2, with tanks for sediment and runoff collectors were set parallel to the inclination of 32° at 212 m altitude. During the field experiment samples were collected biweekly. The soil samples were taken once during the vegetation period for characterization and description of the soil condition and chemistry. The anti-erosion and hydrological role of the forest is among the most important ecological and protective functions of forest ecosystems. Annual runoff coefficient on the investigated type of vegetation cover was small and did not exceed 10 % of total annual rainfall. The crowns of these species mitigate the detrimental activity of raindrops, retain a considerable quantity of precipitation and filter the rest of precipitation through the crowns onto the surface of friable and permeable forest soil.
