Short summary

This study elucidates controls on temporal variability in DOM concentration and quality in stream water draining a bog and a forested peaty riparian zone, particularly considering drought and storm flow events. DOM quality was monitored using spectrofluorometric indices (SUVA₂₅₄, SR and FI) and PARAFAC modeling of EEMs. DOM quality depended clearly on hydrologic preconditions and season. Moreover, the forested peaty riparian zone generated most variability in headwater DOM quantity and quality.
