We present a new way to detect snowmelt using daily cycles in streamflow driven by solar radiation. Results show that warmer sites have earlier and more intermittent snowmelt than colder sites, and the timing of early snowmelt events is strongly correlated with the timing of streamflow volume. A space-for-time substitution shows greater sensitivity of streamflow timing to climate change in colder rather than in warmer places, which is then contrasted with land surface simulations.

Lateral carbon fluxes from terrestrial to aquatic systems remain central uncertainties in determining ecosystem carbon balance. This work explores how temperature and hydrology control production and export of dissolved organic carbon (DOC) at the catchment scale. Results illustrate the asynchrony of DOC production, controlled by temperature, and export, governed by flow paths; concentration–discharge relationships are determined by the relative contribution of shallow versus groundwater flow.

The loss and gain of surface water (variable inundation) is a common process across Earth. Global change shifts variable inundation dynamics, highlighting a need for unified understanding that transcends individual variably inundated ecosystems (VIEs). We review literature, highlight challenges, and emphasize opportunities to generate transferable knowledge by viewing VIEs through a common lens. We aim to inspire the emergence of a cross-VIE community based on a proposed continuum approach.

Climate change can significantly impact river runoff; however, predicting future runoff is challenging. Using historical runoff gauge data to evaluate model performances in runoff simulations for the Mekong River, we quantify future runoff changes in the Mekong River with the best simulation combination. Results suggest a significant increase in the annual runoff, along with varied seasonal distributions, thus heightening the need for adapted water resource management measures.

Watersheds are the fundamental Earth surface functioning unit that connects the land to aquatic systems. Here we present the recently developed BioRT-Flux-PIHM v1.0, a watershed-scale biogeochemical reactive transport model, to improve our ability to understand and predict solute export and water quality. The model has been verified against the benchmark code CrunchTope and has recently been applied to understand reactive transport processes in multiple watersheds of different conditions.

Carbonate weathering is essential in regulating carbon cycle at the century timescale. Plant roots accelerate weathering by elevating soil CO2 via respiration. It however remains poorly understood how and how much rooting characteristics modify flow paths and weathering. This work indicates that deepening roots in woodlands can enhance carbonate weathering by promoting recharge and CO2–carbonate contact in the deep, carbonate-abundant subsurface.

The relationship among glacier melt, groundwater, and streamflow remains highly uncertain, especially in tropical glacierized watersheds in response to climate. We implemented a multi-method approach and found that melt contribution varies considerably and may drive streamflow variability at hourly to multi-year timescales, rather than buffer it, as commonly thought. Some of the melt contribution occurs through groundwater pathways, resulting in longer timescale interactions with streamflow.

Ephemeral snowpacks are snowpacks that persist for less than 2 months. We show that ephemeral snowpacks melt earlier and provide less soil water input in the spring. Elevation is strongly correlated with whether snowpacks are ephemeral or seasonal. Snowpacks were also more likely to be ephemeral on south-facing slopes than north-facing slopes at high elevations. In warm years, the Great Basin shifts to ephemerally dominant as rain becomes more prevalent at increasing elevations.

Focusing on the usage of integrated models and in situ Earth observatory networks, three challenges are identified to advance understanding of ESD, in particular to strengthen links between biotic and abiotic, and above- and below-ground processes. We propose developing a model platform for interdisciplinary usage, to formalize current network infrastructure based on complementarities and operational synergies, and to extend the reanalysis concept to the ecosystem and critical zone.

The phase of precipitation as rain or snow is fundamental to hydrological processes and water resources. Despite its importance, the methods used to predict precipitation phase are inconsistent and often overly simplified. We review these methods and underlying mechanisms that control phase. We present a vision to meet important research gaps needed to improve prediction, including new field-based and remote measurements, validating new and existing methods, and expanding regional prediction.

This review's objective is to demonstrate the transformative potential of lidar by critically assessing both challenges and opportunities for transdisciplinary lidar applications in geomorphology, hydrology, and ecology. We find that using lidar to its full potential will require numerous advances, including more powerful open-source processing tools, new lidar acquisition technologies, and improved integration with physically based models and complementary observations.

The peatland dissolved organic carbon (DOC) lost through aquatic exports can offset a significant proportion of the ecosystem carbon balance. Hence, we propose a new approach to better estimate the DOC exports based on the specific contribution of a boreal peatland (Canada) during periods of high flow. In addition, we studied the relations between DOC concentrations and stream discharge in order to better understand the DOC export mechanisms under contrasted hydrometeorological conditions.

Riverbeds are densely populated with microorganisms which catalyze ecologically relevant processes. To study this complex zone, we tested pore-water extraction with microfilter tubes. The method was found to be suitable for the measurement of dissolved solutes but less so for gases. The pumping rate during sample extraction strongly influenced gas analyses in the samples. The combination with an optical oxygen sensor and a temperature monitoring system was found to be highly valuable.

A non-invasive geophysical method (spectral induced polarization, SIP) was used to characterize and predict solute transport patterns in soil columns. Our results show that SIP-based breakthrough curve (BTC) analysis is superior over conventional outflow-based analysis as it can characterize system heterogeneity and is superior over electrical-conductivity-based analysis as it is capable of distinguishing between the adsorption end-members without the need for sampling.

This study investigates the drivers of spatial variations in stream water quality in poorly studied headwater catchments and includes multiple elements involved in major water quality issues, such as eutrophication. We used a regional public dataset of monthly stream water concentrations monitored for 10 years over 185 agricultural catchments. We found a spatial and seasonal opposition between carbon and nitrogen concentrations, while phosphorus concentrations showed another spatial pattern.

We investigated the linkage between contaminant mobilization in catchments and their mitigation in vegetated treatment systems (VTSs). We identified different patterns in chemographs recorded at the inlet of a VTS, indicating distinct mobilization patterns that were associated with similar source areas, transport pathways, and discharge dynamics. Peak concentration reduction in the VTS was strongest for sharp-peaked chemographs, suggesting that dispersion was the principle mitigation process.

In soil aquifer treatment (a soil-based treatment for wastewater), infiltration ponds are operated in flooding and drying cycles, and the reclaimed water may be used for irrigation. We tested the effect of hydraulic operation on the biogeochemical system via long-column experiments. We found that longer drying periods not only were beneficial for the upper area of the profile but also increased the volume of the system that maintained oxidizing conditions.

High-latitude permafrost environments are changing rapidly due impacts and feedbacks associated with climate warming. We used streamflow and DOC concentrations as well as export estimates and optical indices to better understand how different surface water bodies transport and process dissolved material over multiple seasons and years. Information on DOM quality provides insight into organic material sources and possible composition changes related to higher summer rainfall in summer/fall.

A multiplexed pumping system (MPS) for obtaining continuous water quality data at multiple locations was previously reported. The existing design was not practical for sampling water in volume-limited applications such as small mesocosms or porewater sampling. This paper discusses the design and performance of a small-volume MPS and illustrates two applications, showing spatial variability in replicate in situ mesocosms and short-circuiting in a woodchip bioreactor using porewater sampling.

Artificial water bodies are a major source of methane and an important contributor to flooded land greenhouse gas emissions. Past studies focussed on large water supply or hydropower reservoirs with small artificial water bodies (ponds) almost completely ignored. This regional study demonstrated ponds accounted for one-third of flooded land surface area and emitted over 1.6 million t CO2 eq. yr−1 (10 % of land use sector emissions). Ponds should be included in regional GHG inventories.

The dual nitrate isotope technique is one of the most commonly used approaches to study the origin and fate of N introduced in aquifers. In this study, we first demonstrate a large attenuation of groundwater N at a former industrial site, especially at the interface between surface and groundwater. We also provide evidence for a switch in the oxygen isotopic signature of groundwater due to this extensive N attenuation. This could be used to better quantify N attenuation processes in aquifers.

The influence of riparian evapotranspiration (ET) on stream hydrology and chemistry is poorly understood. We investigated temporal changes in riparian ET, stream discharge and nutrient chemistry along a Mediterranean catchment. Despite being a small component of annual water budgets (4.5 %), our results highlight that riparian ET drives stream and groundwater hydrology in Mediterranean catchments and, further, question the potential of the riparian zone as a natural filter of nitrogen loads.

The goal of this study was to compare how differences in urban stream restoration and sanitary infrastructure affect sources and fluxes of water and nutrients. Stream restoration reduced peak discharge and lowered nutrient export compared to unrestored streams, but was similar to a stream with upland stormwater management. The primary source of nitrate at all sites was leaky sanitary sewers, suggesting that combining stream restoration with sanitary pipe repairs may help reduce nutrient loads.

Development of unconventional energy resources if often associated with public concerns regarding potential contamination of shallow groundwater due to methane leakage. We combined chemical and isotopic analyses of gas and water samples obtained from shallow aquifers in Alberta (Canada) to assess baseline methane sources and found that > 67 % of the samples contained biogenic methane formed in situ in the aquifers. There was no evidence of deep thermogenic methane migration into shallow aquifers.

Short summary
We develop stream water chemistry to pair with the existing CAMELS (Catchment Attributes and Meteorology for Large-sample Studies) dataset. The newly developed dataset, termed CAMELS-Chem, includes common stream water chemistry constituents and wet deposition chemistry in 516 catchments. Examples show the value of CAMELS-Chem to trend and spatial analyses, as well as its limitations in sampling length and consistency.
We develop stream water chemistry to pair with the existing CAMELS (Catchment Attributes and...
