Short summary
A 40-year hydro-climatic time series from the Krycklan catchment revealed warmer winters associated with higher baseflow and lower summer baseflow. Climate index models suggest that while warmer winters enhance baseflow, they reduce water reserves necessary for summer baseflow. This was supported by an increasing winter precipitation isotope signal in winter baseflow, contrasted with a decreasing isotope signal in summer baseflow.

Discrete riparian inflow points (DRIPs) transport dissolved organic carbon (DOC) from large areas to discrete sections of streams, yet the mechanisms by which DRIPs affect stream DOC concentration, cycling, and export are still unknown. Here, we tested four models that account for different hydrologic and biological representations to show that DRIPs generally reduce DOC exports by either diluting stream DOC (snowmelt period) or promoting aquatic metabolism (summer).

Historically, many peatlands in the boreal region have been drained for timber production. Given the prospects of a drier future due to climate change, wetland restorations are now increasing. Better maps hold the key to insights into restoration targets and land-use management policies, and maps are often the number one decision-support tool. We use an AI-developed soil moisture map based on laser scanning data to illustrate how the mapping of peatlands can be improved across an entire nation.

Terrain indices constitute a good candidate for modelling the spatial variation of soil moisture conditions in many landscapes. In this study, we evaluate nine terrain indices on varying DEM resolution and user-defined thresholds with validation using an extensive field soil moisture class inventory. We demonstrate the importance of field validation for selecting the appropriate DEM resolution and user-defined thresholds and that failing to do so can result in ambiguous and incorrect results.

The effects of climate warming on carbon cycling across the Arctic–boreal zone (ABZ) remain poorly understood due to the relatively limited distribution of ABZ flux sites. Fortunately, this flux network is constantly increasing, but new measurements are published in various platforms, making it challenging to understand the ABZ carbon cycle as a whole. Here, we compiled a new database of Arctic–boreal CO2 fluxes to help facilitate large-scale assessments of the ABZ carbon cycle.

A numerical model was used to estimate annual and seasonal mean travel times across 14 long-term nested monitored catchments in the boreal region. The estimated travel times and young water fractions were consistent with observed variations of base cation concentration and stable water isotopes, δ18O. Soil type was the most important factor regulating the variation in mean travel times among sub-catchments, while the areal coverage of mires increased the young water fraction.

The hydrologic cycle is one of the greatest natural processes on Earth and strongly influences both regional and global climate as well as ecosystem functioning. Results from this study clearly show the central role trees play in regulating the water cycle of boreal catchments, implying that forest management impacts on stand structure as well as climate change effects on tree growth are likely to have large cascading effects on the way water moves through boreal forested landscapes.

Near-stream areas, or riparian zones, are important for the health of streams and rivers. If these areas are disturbed by forestry or other anthropogenic activity, the water quality and all life in streams may be at risk. We examined which riparian areas are particularly sensitive. We found that only a few wet areas bring most of the rainwater from the landscape to the stream, and they have a unique water quality. In order to maintain healthy streams and rivers, these areas should be protected.

We adapted and used a spatially distributed eco-hydrological model, EcH2O-iso, to temporally evaluate the influence of soil freeze–thaw dynamics on evaporation and transpiration fluxes in a northern Swedish catchment. We used multi-criterion calibration over multiple years and found an early-season influence of soil frost on transpiration water ages. This work provides a framework for quantifying the current and future interactions of soil water, evaporation, and transpiration.

Forest management is widely used to mitigate climate change. However, forest greenhouse gas (GHG) budgets neglect to consider that clear-cuts often release carbon and nitrogen into streams and lakes and may affect aquatic GHG emissions. Here, we show that such emissions remain unaffected by experimental boreal forest clear-cutting despite increased groundwater carbon dioxide and methane concentrations, highlighting that riparian zones or in-stream processes may have buffered clear-cut leachates.

We estimated water ages in the upper critical zone with a soil physical model (SWIS) and found that the age of water stored in the soil, as well as of water leaving the soil via evaporation, transpiration, or recharge, was younger the higher soil water storage (inverse storage effect). Travel times of transpiration and evaporation were different. We conceptualized the subsurface into fast and slow flow domains and the water was usually half as young in the fast as in the slow flow domain.

The quality of dissolved organic carbon (DOC), especially its color, is a defining feature of freshwater ecosystems. We found that colored DOC fractions are surprisingly resistant to natural degradation during water transit through many brown-water lakes. This is explained by the dominance of microbial processes that appear to selectively remove noncolored DOC. However, in lakes where sunlight degradation plays a relatively larger role, significant DOC bleaching occurs.

Which is the dominant effect on evapotranspiration in northern forests, an increase by recent forests expansion or a decrease by the water use response due to increasing CO2 concentrations? We determined the dominant effect during the period 1961–2012 in 65 Swedish basins. We used the Budyko framework to study the hydroclimatic movements in Budyko space. Our findings suggest that forest expansion is the dominant driver of long-term and large-scale evapotranspiration changes.

We used the Spatially Distributed Tracer-Aided Rainfall-Runoff model (STARR) to simulate streamflows, stable water isotope ratios, snowpack dynamics, and water ages in three snow-influenced experimental catchments with exceptionally long and rich datasets. Our simulations reproduced the hydrological observations in all three catchments, suggested contrasting stream water age distributions between catchments, and demonstrated the importance of snow isotope processes in tracer-aided modelling.

The riparian zone is the narrow strip of land that lines a watercourse. This is the last soil that the groundwater is in contact with before it enters the stream and it therefore has a high impact on the water quality. In this paper we show that many elements occur in elevated concentrations in the peat-like riparian zone of boreal headwaters and that this also leads to elevated concentrations in the streams. Hence, understanding riparian soils is crucial for a sustainable management of streams.

This paper presents a biogeochemical and ecological data set from the Kangerlussuaq region, western Greenland. The data set is used to conceptualize and model terrestrial and limnic ecosystems as well as the land–lake linkage. Both biotic and abiotic data is presented and will be used for biogeochemical mass-balance and transport calculations. The data set constitutes an important source in order to understand and describe accumulation and flow of matter within periglacial landscapes.

This paper presents an important framework to improve hydrologic projections in cold regions. Hydrologic modelling/projections are often based on model calibration to long-term data. Here we used dry and wet years as a proxy to quantify uncertainty in projecting hydrologic extremes. We showed that projections based on long-term data could underestimate runoff by up to 35% in boreal regions. We believe the hydrologic modelling community will benefit from new insights derived from this study.

Restoration is suggested as a strategy to reduce the large greenhouse gas (GHG) emissions from abandoned peat extraction areas. This study investigated GHG fluxes in restored sites with high and low water table level in comparison to a bare peat area. The results show that on the annual scale, both restored sites acted as similar GHG sources 3 years after restoration. However, their net GHG emissions were only half of those from the bare peat area, indicating considerable mitigation potential.

The scientific question that is addressed in this study is how forest disturbance affects organic and inorganic nitrogen export from a boreal landscape. The key findings are that the mobilization of inorganic nitrogen from the terrestrial environment to streams increased strongly as a response to harvesting, but the stream network removed a major fraction of this load before it reached the outlet, while organic nitrogen was not removed and transported downstream.

Short summary
Carbon dioxide transport between the terrestrial and aquatic systems was dominated by export from the near-stream riparian zone. Over the year, riparian export was highest during autumn storms and the spring snowmelt event. This resulted in high downstream export during these periods with vertical evasion from the stream surface accounting for 60% of the total stream water export, highlighting the importance of evasion to carbon export via the aquatic conduit.

Floodplains can be constructed along agricultural streams with the purpose of increasing water residence time, thereby reducing instream erosion and intercepting nutrient export. In this paper we show how this remediation measure can reduce phosphorus concentrations by up to 30 % through optimized floodplain designs and placement. These reductions were primarily facilitated by protection against erosion rather than by the promotion of deposition on floodplains.

Water-use studies comparing pine and Eucalyptus are limited. This study used internationally recognized methods to measure water use by Eucalyptus and pine over two seasons. Results showed that, over one season, pine used more water than Eucalyptus, which was contrary to previous long-term studies. However, the Eucalyptus site was found to be water stressed. This study concluded that the observed water stress and reduced transpiration rates must be included in hydrological models.

Miombo woodland plants continue to lose water even during the driest part of the year. This appears to be facilitated by the adapted features such as deep rooting (beyond 5 m) with access to deep soil moisture, potentially even ground water. It appears the trend and amount of water that the plants lose is correlated more to the available energy. This loss of water in the dry season by miombo woodland plants appears to be incorrectly captured by satellite-based evaporation estimates.

Dams are an important and rapidly growing means of energy generation in the Tropical Andes of South America. To assess the impacts of dams in the region, we assessed differences in the upstream and downstream water quality of all hydropower dams in Colombia. We found evidence of substantial dam-induced changes in water temperature, dissolved oxygen concentration and suspended sediments. Dam-induced changes in Colombian waters violate regulations and are likely impacting aquatic life.

The Belgian city of Spa is known worldwide for its ferruginous and naturally sparkling groundwater springs that gave their name to the bathing tradition commonly called

Thanks to new analysis on groundwater samples, particularly carbon and helium isotopes together with dissolved gases, this study has demonstrated that the volcanic origin of the CO2 is presumably from the neighboring Eifel volcanic fields.

A methodology is developed for a new hydraulic characterization of continental hydrological basins. For this purpose, the division of wells into flow stretches with different hydraulic behaviour is made according to the results of the flowmeter, supposing that the hypothesis hydraulic heads of the deepest flow stretches of the well do not necessarily match the head shown by the overall well.

The quality control and optimization of soil aquifer treatment (SAT) performance is challenging due to the multiple factors and costs involved. We installed in situ subsurface monitoring sensors that provided continuous high-resolution monitoring of the biochemical and physical conditions of an active SAT system. Data analysis facilitated the determination of the optimal drying and wetting stages, which are critical for suitable SAT management.

Data support is crucial for the research of conflict and cooperation on transboundary rivers. Conventional, manual constructions of datasets cannot meet the requirements for fast updates in the big data era. This study brings up a revised methodological framework, based on the conventional method, and a toolkit for the news media dataset tracking of conflict and cooperation dynamics on transboundary rivers. A dataset with good tradeoffs between data relevance and coverage is generated.

Sand dams capture and store water for use during the dry season in rural communities. A year long field study of three sand dams in Tanzania showed that sand dams are not a suitable habitat for aquatic insects. They capture plenty of water, but most is evaporated during the first few months of the dry season. Sand dams positively impact vegetation and minimally impact erosion. Community water security can be increased by sand dams, but site characteristics and construction are important factors.

The impact of city trees for intercepting rainfall is quantified using measurements and modeling tools. The measurements show that an important amount of rainfall is intercepted, limiting the amount of water reaching the ground. Models are used to extrapolate the measurement results. The performance of two specialized interception models and one water balance model is evaluated. Our results show that the performance of the water balance model is similar to the specialized interception models.

This research examines what processes drive the location and strength of groundwater springs within a peatland environment. Using temperature and geophysical methods, we demonstrate that the relationship between regional groundwater flow gradients and the basin shape below the peatland surface control where groundwater springs occur. Understanding this relationship will support effective restoration efforts, as groundwater spring locations are important to overall peatland function and ecology.

Games are an optimal way to teach about water resource sharing, as they allow real-world scenarios to be explored. We look at how games can be used to teach about water resource sharing, by both playing and developing water games. An evaluation of the web-based game Irrigania found Irrigania to be an effective and easy tool to incorporate into curriculum, and a course on developing water games encouraged students to think about water resource sharing in a more critical and insightful way.

The paper includes a review of the current state of high-frequency monitoring in groundwater and surface waters as an outcome of a special issue of HESS and four sessions at EGU on this topic. The focus of the paper is to look at how high-frequency monitoring can be used as a valuable support to assess the management efforts under various EU directives. We conclude that we in future will see a transition from research to implementation in operational monitoring use of high-frequency sensors.

Rangelands, from grasslands to woodlands, cover much of the earth. These areas face great pressure to meet growing water needs. Data on large-scale dynamics that drive water planning remain rare. Our watershed-scale results challenge simplistic hydrological assumptions. Streamflow was resilient to dramatic landscape changes. These changes did shape sediment yield, affecting water storage. Understanding these processes is vital to projections of rangeland water resources in a changing world.

Semi-structured interviews provide an effective and efficient way of collecting qualitative and quantitative data on water use practices. Interviews are organised around a topic guide, which helps lead the conversation while allowing sufficient opportunity to identify issues previously unknown to the researcher. The use of semi-structured interviews could significantly and quickly improve insight on water resources, leading to more realistic future management options and increased water security.

Controlled drainage has been recognized as an effective option to optimize soil moisture conditions for agriculture and to reduce unnecessary losses of fresh water and nutrients. For a grassland field in the Netherlands, we measured the changes in the field water and solute balance after introducing controlled drainage. We concluded that controlled drainage reduced the drain discharge and increased the groundwater storage in the field, but did not have clear positive effects for water quality.

Based on low-altitude aerial infrared surveys, around 370 groundwater–surface water interaction sites were located. Longitudinal temperature patterns, stable isotopes and dissolved silica composition of the studied rivers differed. Interaction sites identified in the proximity of 12 municipal water plants during low-flow seasons should be considered as potential risk areas during flood periods and should be taken under consideration in river basin management under changing climatic situations.

We studied long-term daily records of rainfall and streamflow of the Incomati River basin in southern Africa. We used statistical analysis and the Indicators of Hydrologic Alteration tool to describe the spatial and temporal variability flow regime. We found significant declining trends in October flows, and low flow indicators; however, no significant trend was found in rainfall. Land use and flow regulation are larger drivers of temporal changes in streamflow than climatic forces in the basin.

High-resolution phosphorus and flow data were used to gauge the effects of diffuse (soil P) and point source (septic tank system) mitigation measures in two flashy headwater river catchments. Over 4 years the data indicated an overall increase in P concentration in defined high flow ranges and low flow P concentration showed little change. The work indicates fractured responses to catchment management advice and mitigation which were also affected by variations in seasonal hydrometeorology.

The mitigation of excess nitrogen and phosphorus in river waters requires costly measures. Therefore it is essential to use reliable monitoring methods to select adequate mitigation strategies. Here we show that more development is needed before passive samplers can be considered as reliable alternative for sampling nutrients in stream. We also showed that although continuous sampling is expensive, its reliability precludes unnecessarily high implementation costs of mitigation measures.

Short summary
There is an increasing interest in rewetting drained peatlands to regain their important ecosystem functions. However, as peatland rewetting is a relatively new strategy, the scientific foundation for this approach is not solid. Therefore, we investigated the impact of rewetting on flood mitigation using high-resolution hydrological field observations. Our results showed that peatland rewetting significantly reduced peak flow and runoff coefficient and mitigated flashy hydrograph responses.
