Headwaters biogeochemistry focused on different rainfall-runoff conditions, and the role of waterlogged areas
Original language description
River headwaters have a high environmental value. Unfortunately, the biogeochemical process in headwaters in context of different rainfall-runoff conditions and specific land cover have not been fully examined. This study focuses on changes in correlations of 16 biogeochemical parameters related to different types of rainfall-runoff events and land cover conditions for eight headwater catchments in Central Europe. Multiple methods as linear regression, Spearman rank correlation, Principal Components Analysis and C/Q hysteresis loops revealed main relationships. Presence of peatlands and waterlogged spruce forests had decisive influence on the biogeochemistry (mainly for COD(Mn), humins, Fe, P-PO4(3-) TP, and N-NO3(-)). The strongest positive correlation of organic matter (COD(Mn)) and Fe is represented in a catchment with the largest area of damaged forest (70 %), but with a smaller proportion of wetlands (8 %). High flow rates influence the release of greater amounts of organic matter and N-NO3(-).
