Headwaters biogeochemistry focused on different rainfall-runoff conditions, and the role of waterlogged areas: a comparative study of Czech mountains

Popis výsledku v původním jazyce

This study focuses on changes of biogeochemical parameters related to variable rainfall-runoff conditions and to land cover types for eight headwater catchments in Central Europe. Linear regression, Spearman rank correlation, Principal Components Analysis and C/Q hysteresis loops revealed main relationships. Presence of peatbogs and waterlogged spruce forests had decisive influence on the biogeochemistry (COD(Mn), humins, Fe, P-PO4(3-) TP, N-NO3(-)). The strongest positive correlation of organic matter and Fe is represented in a catchment with the largest area of damaged forest (70 %), but with a smaller proportion of waterlogged areas (8 %). High flow rates influence greater release of organic matter and N-NO3(-). Catchment with highest (80 %) peatbog cover and catchment after revitalization showed similar behaviour in terms of water biogeochemistry. The type of rainfall-runoff event affected the velocity of pH changes, whereas the electric conductivity (EC) variability was controlled also by the catchment characteristics and hydrological preconditions.
