Sažetak
Background and Purpose: Water in the forest ecosystem can be present in the various forms. The hydrological water cycle unfolds via fundamental hydrological processes such as evapotranspiration, precipitation, infiltration and outflow. Certain infrastructure works and recent climate changes within lowland forest areas have resulted in changes to flood water and groundwater trends, and to quantities of precipitation and evapotranspiration. One of the chemical water quality indicators is the presence of metals in water. Higher metal concentrations in natural waters are undesirable as they are polluters of aquatic systems and detrimental to living organisms. Particularly dangerous are cadmium and lead. The objective of this paper was to analyse watercourse levels, ground water depths, and relations between precipitation waters, flood waters, ground waters, relative air humidity and evapotranspiration. An additional objective was to analyse pollution of precipitation and flood waters in lowland forest ecosystems. Materials and Methods: The study was conducted in the Posavina region of Croatia. Precipitation data from the Nova Gradiška meteorological station, watercourse levels of the Sava River and groundwater depth data from piezometer stations were used in the analysis of the hydrological relations. For water quality analysis, precipitation was collected at six sampler sites during the spring of 2015 and 2016. Flood water and precipitations was collected in three repetitions during the spring of 2015 and 2016. Results: Trends of the Sava River water levels and ground water levels dropped significantly. The precipitation volume trend in the study area was positive, but not statistically significant, while evapotranspiration amounts increased significantly. Conclusions: A significant correlation has found between particular water forms in the hydrological cycle, i.e. between precipitation waters, flood waters and ground waters, and between relative air humidity and evapotranspiration. No pollution of precipitation waters and flood waters with metals was found.
