Response of dissolved organic carbon to rainfall-runoff events in streams draining peatbogs
Popis výsledku v původním jazyce
The presented study investigates the dynamics of DOC concentrations in headwater peatbog areas with respect to the extreme rainfall-runoff (R-R) events hydrometeorological catchment preconditions. The main data sources were automatic devices for monitoring of groundwater level, discharges and rainfalls installed in the Vydra River catchment and one automatic water sampler ISCO in sub-catchment of the Rokytka River basin in the Šumava National Park. Changes in groundwater level and discharges had the greatest influence on DOC concentrations. Higher mean and maximum DOC were measured during events after a longer period without an extreme R-R event. The greater lag time of maximum DOC after peak flow and the higher mean DOC during the event were primarily due to hydrometeorological preconditions of the catchment. The highest DOC was in autumn after previous summer period with low discharges and low groundwater level. DOC was also positively corelated with air and water temperatures.
