Effects of human land use on the terrestrial and aquatic sources of fluvial organic matter in a temperate river basin (The Meuse River, Belgium)

Abstract: The impact of human activities on the concentrations and composition of dissolved organic matter (DOM) and particulate organic matter (POM) was investigated in the Walloon Region of the Meuse River basin (Belgium). Water samples were collected at different hydrological periods along a gradient of human disturbance (50 sampling sites ranging from 8.0 to 20,407 km 2 ) and during a 1.5 year monitoring of the Meuse River at the city of Liège. This dataset was completed by the characterization of the DOM pool in gr… Show more

“…TSM, POC/DOC and DIN patterns reflect the delivery of nutrients, particulate organic matter and DOM to fluvial systems from agricultural catchments. A parallel study showed the increasing fraction of agriculture cover of the catchment also affected the quality of DOM delivered to the rivers that tended to be more labile (Lambert et al, 2017), in agreement with a similar study in German rivers (Bodmer et al, 2016). The delivery of more labile DOM is consistent with the decrease of O 2 and increase of pCO 2 and CH 4 with the increasing fraction of agriculture cover due to enhanced in-stream microbial activity.…”

“…4) that characterizes in-stream microbially produced compounds (Lambert et al, 2017). Bodmer et al (2016) showed a similar correlation between pCO 2 and DOM composition across a spatial gradient of different rivers, while here we show a correlation between those same quantities at a single site but across seasons.…”

“…We compared our PARAFAC model results to published literature and other models in the OpenFluor database (Murphy et al, ). The humic‐like C2 identified in SLW matched components from other models in the OpenFluor database (95% similarity cutoff): a component that was produced along a river‐to‐marine transition in an Arctic river delta in Siberia (Gonçalves‐Araujo et al, ), a component that was linked to microbial degradation of FDOM in five large Arctic rivers (Walker et al, ), and a component from Belgian rivers, which was also linked to microbial activity (Lambert et al, ). SLW's C2 was similar, in terms of its excitation/emission maxima, to the mixture of humic peaks commonly associated with coastal environments (Coble, ), and microbial degradation and production of DOM in Antarctic surface lakes (Cory & McKnight, ).…”

“…Modeled soil C : N ratios from earlier work by Henrys et al () together with land cover classification (LCM2007) and population density statistics have been used in this study to evaluate their relative importance as predictors of DOM stoichiometry in streams. Land cover data have been used extensively in the past to explain variations in DOM composition (Kothawala et al ; Lambert et al ; Singh et al ). Outcomes from this study indicate that the SOM pool is important across a range of environments in controlling riverine DOM composition.…”
