Riparian Microtopography Affects Event‐Driven Stream DOC Concentrations and DOM Quality in a Forested Headwater Catchment

Journal of Geophysical Research: Biogeosciences, Volume 127, Issue 12, December 2022., 2022
Abstract The transport of dissolved organic carbon (DOC) from the soils to inland waters plays an important role in the global carbon cycle. Widespread increases in DOC concentrations have been observed in surface waters over the last few decades, affecting carbon balances, ecosystem functioning and drinking water treatment.

Rewetting prolongs root growing season in minerotrophic peatlands and mitigates negative drought effects

Journal of Applied Ecology, Volume 59, Issue 8, Page 2106-2116, August 2022., 2022
Rewetting extended the growing season of roots, highlighting the importance of phenology in explaining root productivity in peatlands. A longer growing season allows a longer period of carbon sequestration in form of root biomass and promotes the peatlands' carbon sink function, especially through longer growth in deep soil layers.

Delineating Source Contributions to Stream Dissolved Organic Matter Composition Under Baseflow Conditions in Forested Headwater Catchments

Journal of Geophysical Research: Biogeosciences, Volume 126, Issue 8, August 2021., 2021
Abstract Dissolved organic matter (DOM) composition in streams reflects the dynamic interplay between DOM sources, mobilization mechanisms, and biogeochemical transformations within soils and receiving water bodies. The information regarding DOM sources being mobilized during baseflow can improve our ability to predict hydrological and biogeochemical ...

Plus de 60 ans d’hydrométrie en Nouvelle-Calédonie bilan, pratiques, évolutions et perspectives

LHB Hydroscience Journal, 2022
L’hydrométrie s’est peu à peu organisée en Nouvelle-Calédonie tout d’abord grâce aux efforts de l’ORSTOM, puis de la collectivité territoriale. Les réseaux hydrométriques et pluviométriques ainsi constitués en 2021 permettent de disposer de chroniques ...

Catchment Functioning Under Prolonged Drought Stress: Tracer‐Aided Ecohydrological Modeling in an Intensively Managed Agricultural Catchment

Water Resources Research, Volume 57, Issue 3, March 2021., 2021
Abstract High spatial heterogeneity of catchment properties enhances the variability of ecohydrological responses to changing natural and anthropogenic conditions, like the European‐wide droughts in 2018–2019. Based on new adaptations of a tracer‐aided, process‐based ecohydrological model (EcH2O‐iso), we investigated drought‐induced nonstationary ...

Reactivation of Floodplains in River Restorations: Long‐Term Implications on the Mobility of Floodplain Sediment Deposits

Water Resources Research, Volume 55, Issue 10, Page 8178-8196, October 2019., 2019
Abstract Nowadays, national and international requirements and laws emphasize the “natural” development of river‐floodplain systems. One goal is to increase the connectivity between the river and its floodplains and thus reactivate floodplains as flooding areas, which potentially increases the mobility of fine sediments.
