Short-lived peaks of stem methane emissions from mature black alder (Alnus glutinosa (L.) Gaertn.) - Irrelevant for ecosystem methane budgets? [PDF]

Plant Environ Interact, 2021
Stem and soil CH4 emissions were monitored for two years in a drained (AD) and rewetted (AW) mature alder forest. The rewetted site showed high but short‐lived stem and soil CH4 emissions while the drained site was neutral with respect to CH4 emissions.

Assessment of Heavy Metal Concentrations with Fractionation Method in Sediments and Waters of the Badovci Lake (Kosovo). [PDF]

J Environ Public Health, 2020
The concentrations of thirteen metals (Al, As, Ba, Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, V, and Zn) were analyzed in waters and sediments of the Badovci Lake. The total metal concentrations in the water followed the descending order: Fe > Al > Mn > Cu > Ba > Zn > As > Ni > Pb > V > Co > Cd > Cr, and the total metal content in the sediments also followed the ...

Combining Landsat TIR‐imagery data and ERA5 reanalysis information with different calibration strategies to improve simulations of streamflow and river temperature in the Canadian Subarctic

Hydrological Processes, Volume 37, Issue 10, October 2023., 2023
RMSE of water temperature model for different locations. The RMSE has units of °C. Abstract Arctic and Subarctic environments are among the most vulnerable regions to climate change. Increases in liquid precipitation and changes in snowmelt onset are cited as the main drivers of change in streamflow and water temperature patterns in some of the largest

Integrating two‐dimensional water temperature simulations into a fish habitat model to improve hydro‐ and thermopeaking impact assessment

River Research and Applications, Volume 39, Issue 3, Page 501-521, March 2023., 2023
Abstract Storage hydropower plants, which are an important component of energy production in Switzerland, can lead to hydro‐ and thermopeaking, affecting river habitats and organisms. In this study, we developed an approach for integrating water temperature simulations into a habitat model to assess the impact of both hydro‐ and thermopeaking on the ...

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 ...

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.

Groundwater Storage in High Alpine Catchments and Its Contribution to Streamflow

Water Resources Research, Volume 55, Issue 4, Page 2613-2630, April 2019., 2019
Abstract There is limited knowledge about groundwater storage in alpine catchments, although it might strongly influence how these catchments react to earlier snowmelt due to climate change. The objective of the study was to develop and test a method to quantify seasonal groundwater storage in alpine catchments and evaluate how groundwater storage is ...
