Short summary
Short summary
Greenhouse gas emissions from inland waters vary strongly over space and time, making estimates based on periodic daytime measurements highly uncertain. We developed an automated monitoring system using cost-effective methane and CO2 sensors and improved their accuracy through laboratory calibration and correction methods. Field measurements and simulations show that our system provides reliable emission estimates and that daytime-based CO2 estimates systematically underestimate emissions.

Short summary
Short summary
Peatlands either store carbon or release greenhouse gases depending on climate, water levels, and land management. We present an improved peatland model to better understand these processes. We validate the model at two sites in the Netherlands. The model reproduced observed carbon dioxide and methane exchange. This model can help to improve understanding of peatland emissions in response to environmental change.

Short summary
Drained peatlands release large amounts of carbon dioxide, and raising water levels is widely proposed to reduce these emissions. We measured the yearly carbon balance at twenty sites across Dutch peatlands. Higher water tables were linked to lower emissions, a weak but fairly consistent effect. Site-to-site differences outweighed water level: land use and a clay layer over the peat strongly shaped emissions, so raising water levels works only if each site's intrinsic features are considered.

Short summary
This study explores how mean and extreme river flows respond to annual climate variability. Maps show where river flow is more sensitive to climate in Europe. Maximum flows are generally the most sensitive and minimum flows the least sensitive to precipitation changes. Sensitivities are influenced by many factors like climate, soil, and terrain. These findings improve our understanding of how rivers respond to climate and can support water management and disaster risk reduction across Europe.

Short summary
We combine two types of carbon dioxide (CO2) data from Dutch peatlands in a machine learning model: from fixed measurement towers and from a light research aircraft. We find that emissions increase with deeper water table depths (WTDs) by 4.6 tons of CO2 per hectare per year for each 10 cm deeper WTD on average. The effect is stronger in winter than in summer and varies between locations. This variability should be taken into account when developing mitigation measures.

Short summary
Water infiltration systems in peat meadows commonly reduce groundwater level. Groundwater level fluctuations induce soil volume decreases and increases in both the saturated and unsaturated zone, causing yearly vertical soil movement dynamics of up to 10 cm. Multiyear subsidence rates are of the order of millimeters per year. Such research is vital to increase knowledge of subsidence processes and develop effective measures to reduce land subsidence and greenhouse gas emissions.

Drained peatlands emit 3 % of the global greenhouse gas emissions. Paludiculture is a way to reduce CO2 emissions while at the same time generating an income for landowners. The side effect is the potentially high methane emissions. We found very high methane emissions for broadleaf cattail compared with narrowleaf cattail and water fern. The rewetting was, however, effective to stop CO2 emissions for all species. The highest potential to reduce greenhouse gas emissions had narrowleaf cattail.

Vegetation is a critical component of carbon storage in peatlands but an often-overlooked concept in many peatland models. We developed a new model capable of simulating the response of vegetation to changing environments and management regimes. We evaluated the model against observed chamber data collected at two peatland sites. We found that daily air temperature, water level, harvest frequency and height, and vegetation composition drive methane and carbon dioxide emissions.

Short summary
An Arctic catchment with permafrost responds in a linear fashion: water in=water out. As permafrost thaws, 9 of 10 nested catchments become more non-linear over time. We find upstream catchments have stronger streamflow seasonality and exhibit the most nonlinear storage-discharge relationships. Downstream catchments have the greatest increases in non-linearity over time. These long-term shifts in the storage-discharge relationship are not typically seen in current hydrological models.

In NW Europe only parts of former peatlands remain. When these peatlands formed is not well known but relevant for questions on landscape, climate and archaeology. We investigated the age of Fochteloërveen, using radiocarbon dating and modelling. Results show that peat initiated at several sites 11 000–7000 years ago and expanded rapidly 5000 years ago. Our approach may ultimately be applied to model peat ages outside current remnants and provide a view of these lost landscapes.

Short summary
Draining peat causes high CO2 emissions, and rewetting could potentially help solve this problem. In the dry year 2020 we measured that subsurface irrigation reduced CO2 emissions by 28 % and 83 % on two research sites. We modelled a peat parcel and found that the reduction depends on seepage and weather conditions and increases when using pressurized irrigation or maintaining high ditchwater levels. We found that soil temperature and moisture are suitable as indicators of peat CO2 emissions.

To assess the impact of vegetation on GHG fluxes in peatlands, we developed a new model, Peatland-VU-NUCOM (PVN). These results showed that plant communities impact GHG emissions, indicating that plant community re-establishment is a critical component of peatland restoration. This is the first time that a peatland emissions model investigated the role of re-introducing peat forming vegetation on GHG emissions.

Short summary
An important uncertainty in the modelling of methane emissions from natural wetlands is the wetland area. It is important to get the spatiotemporal covariance between the variables that drive methane emissions right for accurate quantification. Using high-resolution wetland and soil carbon maps, in combination with a simplified methane emission model that is coarsened in six steps from 0.005° to 1°, we find a strong relation between wetland emissions and the model resolution.

Editorial statement
Drained peatlands are a substantial global CO2 source. Using an unprecedented monitoring network, this paper shows that using subsurface water infiltration systems effectively limits CO2 emissions, which can be predicted by carbon exposure. This is a nice example of how adapted management can substantially reduce CO2 emissions from drained peatlands.

Short summary
Drained peatlands cause high CO2 emissions. We assessed the effectiveness of subsurface water infiltration systems (WISs) in reducing CO2 emissions related to increases in water table depth (WTD) on 12 sites for up to 4 years. Results show WISs markedly reduced emissions by 2.1 t CO2-C ha-1 yr-1. The relationship between the amount of carbon above the WTD and CO2 emission was stronger than the relationship between WTD and emission. Long-term monitoring is crucial for accurate emission estimates.
