Accurately estimating groundwater recharge using numerical models is particularly difficult in cold regions with snow and soil freezing. This study evaluated a physics-based model against high-resolution field measurements. Our findings highlight a need for a better representation of soil freezing processes, offering a roadmap for future model development. This leads to more accurate models to aid water resources management decisions in cold climates.

Hybrid forecasting systems combine data-driven methods with physics-based weather and climate models to improve the accuracy of predictions for meteorological and hydroclimatic events such as rainfall, temperature, streamflow, floods, droughts, tropical cyclones, or atmospheric rivers. We review recent developments in hybrid forecasting and outline key challenges and opportunities in the field.

The research deals with the assimilation of in-situ local snow observations in a large-scale spatialized snow modeling framework over the province of Quebec (eastern Canada). The methodology is based on proposing multiple spatialized snow scenarios using the snow model and weighting them according to the available observations. The paper especially focuses on the spatial coherence of the snow scenario proposed in the framework.

The performance of the non-dominated sorting genetic algorithm II (NSGA-II) is compared with a conventional post-processing method of affine kernel dressing. NSGA-II showed its superiority in improving the forecast skill and communicating trade-offs with end-users. It allows the enhancement of the forecast quality since it allows for setting multiple specific objectives from scratch. This flexibility should be considered as a reason to implement hydrologic ensemble prediction systems (H-EPSs).

This article shows a conversion model of snow depth into snow water equivalent (SWE) using an ensemble of artificial neural networks. The novelty is a direct estimation of SWE and the improvement of the estimation by in-depth analysis of network structures. The usage of an ensemble allows a probabilistic estimation and, therefore, a deeper insight. It is a follow-up study of a similar study over Quebec but extends it to the whole area of Canada and improves it further.

Meteorological forecasting agencies constantly work on pushing the limit of predictability farther in time. However, some end users need proof that climate model outputs are ready to be implemented operationally. We show that bias correction is crucial for the use of ECMWF System4 forecasts for the studied area and there is a potential for the use of 1-month-ahead forecasts. Beyond this, forecast performance is equivalent to using past climatology series as inputs to the hydrological model.

In this study we set the basis of an alternative framework to replace the popular cost-loss ratio for the economic assessment of flood forecasting systems. The C-L ratio implicitly considers the decision maker to be risk-neutral, whereas it is rarely the case in real-life emergency situations. Instead of the cost-loss ratio, we propose using a utility function. We show that the decision-maker’s level of risk aversion is a crucial factor in the assessment of the economic value of flood forecasts.

Issuing a good hydrological forecast is challenging because of the numerous sources of uncertainty that lay in the description of the hydrometeorological processes. Several modeling techniques are investigated in this paper to assess how they contribute to the forecast quality. It is shown that the best modeling approach uses several dissimilar techniques that each tackle one source of uncertainty.

Global climate change is causing some previously arid regions to become more humid. Economic downturns in these areas are leading to a decrease in water demand. These factors are further leading to a certain level of under-utilization of existing water supply projects in the area. This study finds that actively releasing ecological water increases the sustainability of these water supply projects. The cost of ecological water supply can be recovered by investment in water-related businesses.

This opinion paper reflects on the risks of overusing groundwater savings to supply permanent water use requirements. Using novel data recently developed for Chile, we reveal how groundwater is being overused, causing ecological and socioeconomic impacts and concealing a Day Zero
scenario. Our argument underscores the need for reformed water allocation rules and sustainable management, shifting from a perception of groundwater as an unlimited source to a finite and vital one.

This study finds that bedroom cities show higher water productivity based on the standard efficiency benchmark of gallons per capita, but core cities that host large businesses show higher water productivity using a basket of economic values like taxes, payroll, and business revenues. Using a broader basket of water productivity benchmarks that consider more of the community’s socio-economic values and goals could inform more balanced and equitable water allocation decisions by policymakers.

People induce and modify droughts. However, we do not know exactly how relevant human and natural processes interact nor how to evaluate the co-evolution of people and water. Prospect theory can help us to explain the emergence of drought impacts leading to failed welfare expectations (“prospects”) due to water shortage. Our approach helps to explain socio-hydrological phenomena, such as reservoir effects, and can contribute to integrated drought management considering the local context.

With intensified extremes under climate change, water demand increases. Every drop of water is more valuable than before when drought is experienced particularly. We developed drought intensity–duration–frequency curves using physical indicators, the deficit in precipitation and streamflow, for a more straightforward interpretation. Tests with the observed major droughts in two climatologically different catchments confirmed the practical applicability of the curves under drought conditions.

Implementation failure is well known to be a major barrier to the success of water resource plans and policies. The motivations and abilities (MOTA) approach attempts to address this barrier, by providing a multi-stakeholder, multilevel tool to assess triggers, motivations and abilities supporting the implementation feasibility of plans. We review existing MOTA applications in various water management contexts and propose several complementary add-in applications to complement the approach.

In residential areas with a high housing density, septic contamination of private wells raises multiple health concerns.

Urban water systems are facing an increasing pressure on their water resources to guarantee safe and sufficient water access. Water managers often use tried and tested strategies like large supply augmentation infrastructure to address water problems. However, these projects do not address key problems and cause water conflicts.

Using publications indexed in the Web of Science, we investigated water resources knowledge development at the river basin scale since 1900 and found that legacy-driven knowledge structures, increasingly homogenized management issues, and largely static cross-disciplinary collaborations dominated highly researched river basins.

There is a clear trade-off between reservoir hydropower generation and the variability in reservoir water release, which can be used to derive water-sharing policies and provide critical insights during riparian negotiations regarding downstream flows supplementing during drought conditions. This type of water-sharing policy can effectively mitigate the water use conflicts between upstream and downstream countries, especially during drought periods.

This study advances the understanding and impacts of drought on wheat, corn, and soybean yields over Argentina's main crop region, where crop production is more intense and represents the main contribution to the country's gross domestic product. Our analysis focuses on drought properties, including the magnitude, frequency at different timescales, duration, and severity. This new approach can be helpful for regional decision-making and planning by water managers and in agricultural contexts.

This study combines a fine-scale weather product with outputs of a hydrological model to construct functional metrics of individual and compound hydroclimatic extremes for agriculture. Then, a yield response function is estimated with individual and compound metrics focusing on corn in the United States during the 1981–2015 period. The findings suggest that metrics of compound hydroclimatic extremes are better predictors of corn yield variations than metrics of individual extremes.

Palaeoclimate information was analysed for eastern Australia to determine when (and where) there was agreement about the timing of wet and dry epochs in the pre-instrumental period (1000–1899). The results show that instrumental records (~1900–present) underestimate the full range of rainfall variability that has occurred. When coupled with projected impacts of climate change and growing demands, these results highlight major challenges for water resource management and infrastructure.

Our research studies whether science depoliticizes water conflicts or instead conflicts politicize science–policy processes. We analyze a water conflict due to the development of large infrastructure. We interviewed key actors in the conflict and replicated the results of water resources models developed to solve the conflict. We found that knowledge produced in isolation has no positive effect in transforming the conflict; instead, its potential could be enhanced if produced collaboratively.

Watershed classification can identify regions expected to respond similarly to disturbance. Methods should extend beyond hydrology to include other environmental questions, such as ecology and water quality. We developed a classification for the Canadian Prairie and identified seven classes defined by watershed characteristics, including elevation, climate, wetland density, and surficial geology. Results provide a basis for evaluating watershed response to land management and climate condition.

Hydrology education strives to teach students both quantitative ability and complex professional skills. Our research shows that role-play simulations are useful to make students able to integrate various analytical skills in complicated settings while not interfering with traditional teaching that fosters their ability to solve mathematical problems. Despite this there are several potential challenging areas in using role-plays, and we therefore suggest ways around these potential roadblocks.

This study applies a two-way coupled agent-based model (ABM) with a river-reservoir management model (RiverWare) to analyze the role of risk perception in water management decisions using the Bayesian inference mapping joined with the cost–loss model.

Many variables, e.g., in hydrology, geology, and social sciences, are only observed at a few distinct measurement locations, and their actual distribution in the entire space remains unknown. We introduce the new geostatistical interpolation method of
quantile kriging, providing an improved estimator and associated uncertainty. It can also host variables, which would not fulfill the implicit presumptions of the traditional geostatistical interpolation methods.

Do experts attach the same meaning as laypeople to terms often used in hydrology such as "river", "flooding" and "downstream"? In this study a survey was completed by 34 experts and 119 laypeople to answer this question. We found that there are some profound differences between experts and laypeople: words like "river" and "river basin" turn out to have a different interpretation between the two groups. However, when using pictures there is much more agreement between the groups.

Decision-making for flood risk management is often the collective effort of professionals within government, NGOs, private practice, and advocacy groups. Our research investigates differences among flood experts within Tompkins County, New York (USA). We explore how they differ in their perceptions of flooding risk, desired project outcomes, and knowledge. We observe substantial differences among experts, and recommend formally acknowledging these perceptions when engaging in flood management.

Socio-hydrological space (SHS) is a concept that enriches the study of socio-hydrology because it helps understand the detailed human–water interactions in a specific location. The concept suggests that the interactions between society and water are place-bound because of differences in social processes and river dynamics. This would be useful for developing interventions under disaster management, but also other development goals. SHS provides a new way of looking at socio-hydrological systems.

At present, the water footprint calculated by the quantitative method of crop production water footprint is only a field-scale water footprint, which does not contain all the water consumption of the crop growth process, so its calculated crop production water footprint is incomplete. In this study, the hydrological model SWAT was used to analyze the real water consumption in the course of crop growth, so that the actual water consumption of the crops could be more accurately reflected.

An analytical framework is developed drawing on ideas of regime shifts from resilience literature to understand the transition between cases where water scarcity is or is not experienced depending on whether water from upstream is or is not available. The analysis shows 386 million people dependent on upstream water to avoid possible stress and 306 million people dependent on upstream water to avoid possible shortage. This provides insights into implications for negotiations between sub-basins.

This paper argues for an alternative approach for socio‒hydrology: detailed case study research. Detailed case study research can increase understanding of how society interacts with hydrology, offers more levers for management than coupled modelling, and facilitates interdisciplinary cooperation. The paper presents a case study of the Dommel Basin in the Netherlands and Belgium and compares this with a published model of the Kissimmee Basin in Florida.

The paper aims to propose a conceptual framework that supports nuanced understanding and analytical assessment of resilience in socio-hydrological contexts. We identify three framings of resilience for different human–water couplings, which have distinct application fields and are used for different water management challenges. To assess and improve socio-hydrological resilience in each type, we introduce a
resilience canvasas a heuristic tool to design bespoke management strategies.

The history of the co-evolution of the coupled human–groundwater system in Cangzhou (a region with the most serious depression cone in the North China Plain) is analyzed with a particular focus on how the groundwater crisis unfolded and how people attempted to settle the crisis. The evolution of the system was substantially impacted by two droughts. Further restoration of groundwater environment could be anticipated, but the occurrence of drought still remains an undetermined external forcing.

The effects of human actions in small-scale water development initiatives and the associated hydrological research activities are basically unspecified. We argue that more explicit attention helps to design more appropriate answers to the challenges faced in field studies. A more systematic approach is proposed that would be useful when designing field projects: two sets of questions on (1) dealing with surprises and (2) cost–benefits of data gathering.

To help geo-scientists prepare for TV appearances, we review the scientific literature on effective science communication related to TV. We identify six main themes: scientist motivation, target audience, narratives and storytelling, jargon and information transfer, relationship between scientists and journalists, and stereotypes of scientists on TV. We provide a detailed case study as illustration for each theme.

This paper provides empirical evidence for the value of using a psychology-based approach to communication of hydrology and hazards. It demonstrates the use of the "mental models" approach to risk assessment used in a regional geoscience context to explore the conceptions of the geological subsurface between experts and non-experts, and how that impacts on communication.

The paper draws attention to the fact that green water (soil moisture returning to the atmosphere through evaporation) is a scarce resource, because its availability is limited and there are competing demands for green water. Around 80 indicators of green water availability and scarcity are reviewed and classified based on their scope and purpose of measurement. This is useful in order to properly include limitations in green water availability in water scarcity assessments.

Hydrological drought types in cold climates have complex causing factors and impacts. In Austria and Norway, a lack of snowmelt is mainly related to below-normal winter precipitation, and a lack of glaciermelt is mainly related to below-normal summer temperature. These and other hydrological drought types impacted hydropower production, water supply, and agriculture in Europe and the US in the recent and far past. For selected drought events in Norway impacts could be coupled to causing factors.

Short summary
Flood forecasts are only useful if they are understood correctly. They are also uncertain, and it is difficult to present all of the information about the forecast and its uncertainty on a map, as it is three dimensional (water depth and extent, in all directions). To overcome this, we interviewed 139 people to understand their preferences in terms of forecast visualization. We propose simple and effective ways of presenting flood forecast maps so that they can be understood and useful.
