Earth Syst. Sci. Data, 13, 4759–4777,Short summary
We present a data set consisting of ice-penetrating-radar internal stratigraphy: 26 internal reflecting horizons that cover the greater Dome C area, East Antarctica, the most extensive IRH data set to date in the region. This data set uses radar surveys collected over the span of 10 years, starting with an airborne international collaboration in 2008 to explore the region, up to the detailed ground-based surveys in support of the European Beyond EPICA – Oldest Ice (BE-OI) project.

We present preliminary analyses of the annual sea salt concentrations and snowfall accumulation in a new East Antarctic ice core, Mount Brown South. We compare this record with an updated Law Dome (Dome Summit South site) ice core record over the period 1975–2016. The Mount Brown South record preserves a stronger and inverse signal for the El Niño–Southern Oscillation (in austral winter and spring) compared to the Law Dome record (in summer).

Analyses of run lengths of Pacific decadal variability (PDV) suggest that there is no significant difference between run lengths in positive and negative phases of PDV and that it is more likely than not that the PDV run length has been non-stationary in the past millennium. This raises concerns about whether variability seen in the instrumental record (the last ~100 years), or even in the shorter 300–400 year paleoclimate reconstructions, is representative of the full range of variability.

We reconstruct the pattern of surface accumulation in the region around Dome C, East Antarctica, over the last 73 kyr. We use internal isochrones interpreted from ice-penetrating radar surveys and a 1-D ice flow model to invert for time-averaged and paleo-accumulation rates. We observe that surface accumulation patterns are stable through the last 73 kyr, consistent with current observed regional precipitation gradients and consistent interactions between prevailing winds and surface slope.

Stochastic rainfall models are required to be be able to assess the reliability of dams used for urban water supply. Traditional Markov chain stochastic models do well at reproducing the mean and variance of rainfall at daily to weekly resolution but fail to simultaneously reproduce the variability of monthly to decadal rainfall. This paper presents four new extensions to Markov chain models that address this decadal deficiency and compares their performance for two field sites.

Regional Antarctic snow accumulation derived from 79 ice core records is evaluated as part of the PAGES Antarctica 2k working group. Our results show that surface mass balance for the total Antarctic ice sheet has increased at a rate of 7 ± 0.13 Gt dec-1 since 1800 AD, representing a net reduction in sea level of ~ 0.02 mm dec-1 since 1800 and ~ 0.04 mm dec-1 since 1900 AD. The largest contribution is from the Antarctic Peninsula.

The oldest dated deep ice core drilled in Antarctica has been retrieved at EPICA Dome C (EDC), reaching ~ 800 000 years. Obtaining an older palaeoclimatic record from Antarctica is one of the greatest challenges of the ice core community. Here, we estimate the age of basal ice in the Dome C area. We find that old ice (> 1.5 Myr) likely exists in two regions a few tens of kilometres away from EDC:

Here we present a revised Law Dome, Dome Summit South (DSS) ice core age model (denoted LD2017) that significantly improves the chronology over the last 88 thousand years. An ensemble approach was used, allowing for the computation of both a median age and associated uncertainty as a function of depth. We use a non-linear interpolation between age ties and unlike previous studies, we made an independent estimate of the snow accumulation rate, where required, for the use of gas based age ties.

To find records of the greenhouse gases found in key periods of climate transition, we need to find sites of unmelted old ice at the base of the Antarctic ice sheet for ice core retrieval. A joint US–Australian–EU team performed a high-resolution survey of such a site (1 km line spacing) near Concordia Station in East Antarctica, using airborne ice-penetrating radar. We found promising targets in rough subglacial terrain, surrounded by subglacial lakes restricted below a minimum hydraulic head.

Earth Syst. Sci. Data, 9, 267–279,Short summary
Antarctic bed topography datasets are interpolated onto low-resolution grids because our observed topography data are sparsely sampled. This has implications for ice-sheet model simulations, especially in regions prone to instability, such as grounding lines, where detailed knowledge of the topography is required. Here, we constructed a high-resolution synthetic bed elevation dataset using observed covariance properties to assess the dependence of simulated ice-sheet dynamics on grid resolution.

We present a study of bromine, iodine and sodium in an ice core from Law Dome, in coastal East Antarctica. We find that bromine and iodine variability at Law Dome is correlated to changes in the area of sea ice along the Law Dome coast as observed by satellite since the early 1970s. These findings are in agreement with a previous study based on MSA and confirm a long-term trend of sea ice decrease for this sector of Antarctica over the 20th century.

We examine the spatiotemporal differences between three TC databases for the southwest Pacific region. In addition, the usefulness of pre-satellite era TC data (1945–1969) is evaluated. While changes in observational technologies from 1945 have undoubtedly improved our ability to detect and monitor TCs, we show that pre-satellite era TC data are not temporally or statistically different to post-satellite era data (1970–present).

This study investigates how tropical cyclones impact urban residents of Fiji, Vanuatu and Tonga. We investigate how people perceive tropical cyclones (TCs), how they are impacted and what methods of adaptation are used to offset damage from TC activity. We propose a conceptual framework to merge the non-traditional knowledge of weather forecasting and climate science with weather-related traditional knowledge, and explore the possibilities of developing a multidimensional TC forecasting tool.

A 1013-year annual rainfall reconstruction was developed for the Williams River catchment in coastal eastern Australia, based on a linear relationship between sea salt deposition in East Antarctica and rainfall in eastern Australia. The reconstruction allows for the instrumental climate record (~ 100 years) to be assessed in the context of millennial climate variability, allowing for better characterisation of flood and drought risk.

This study details a systematic approach to finding a new high-resolution East Antarctic ice core site. The study initially outlines seven criteria that a new site must fulfil, encompassing specific accumulation, ice dynamics and atmospheric circulation aspects. We then use numerous techniques including Antarctic surface mass balance syntheses, ground-truthing of satellite data by airborne radar surveys and reanalysis products to pinpoint promising regions.

Rainfall intensity-frequency-duration (IFD) relationships are required for the design and planning of water supply and management systems around the world. Currently IFD information is based on the "stationary climate assumption". However, this paper provides evidence of regime shifts in annual maxima rainfall time series using 96 daily rainfall stations and 66 sub-daily rainfall stations across Australia. Importantly, current IFD relationships may under- or overestimate the design rainfall.

The Law Dome, East Antarctica snow accumulation record is extended back to 22 BCE using a power-law vertical strain rate model. The periods of 380-442, 727-783 and 1970-2009 CE show above-average snow accumulation rates, while 663-704, 933-975 and 1429-1468 CE were below average. The calculated snow accumulation rates show good correlation with atmospheric reanalysis estimates and significant spatial correlation over a wide expanse of East Antarctica.

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. A structural shift of water resources knowledge development to cope with the rapidly changing hydrological systems and associated management issues is urgently needed.

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.

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.

Proper water availability for the right place and time in a changing climate requires analysis of complex scientific, technical, socioeconomic, regulatory, and political issues. A Water-Energy-Food Nexus Phosphate (WEF-P) Tool, based on integrating supply chain processes, transportation, and water–energy footprints could assess the various scenarios to offer an effective means of ensuring sustainable management of limited resources to both agricultural areas and the phosphate industry.

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. The calibration results capture the dynamics of historical irrigated area and streamflow changes and suggest that the proposed framework improves the representation of human decision-making processes compared to conventional rule-based ABMs.

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.

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.

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.
