The contemporary stable isotope hydrology of Lake Suigetsu and surrounding catchment (Japan) and its implications for sediment-derived palaeoclimate records

Charlie Rex, Jonathan Tyler, Kazuyoshi Nagaya, et al.

Published: 2023-10-03
Subjects: Fresh Water Studies, Geochemistry, Hydrology, Meteorology

The Lake Suigetsu sediment cores exemplify a high-quality archive of palaeoclimatic change in East Asia during the past 150 ka. Robust interpretation of stable isotope-based proxy reconstructions from the Suigetsu cores can be aided by a greater understanding of the factors affecting the isotope composition of the lake and how it relates to that of precipitation. Here we use extended contemporary [...]

Modelling lateral meltwater flow and superimposed ice formation atop Greenland's near-surface ice slabs

Nicole Clerx, Horst Machguth, Andrew Tedstone, et al.

Published: 2023-10-02
Subjects: Glaciology, Hydrology

At high elevations on the Greenland ice sheet meltwater percolates and refreezes in place, and hence does not contribute to mass loss. However, meltwater generation and associated surface runoff is occurring from increasingly higher altitudes, causing changes in firn stratigraphy that have led to the presence of near-surface ice slabs. These ice slabs force meltwater to flow laterally instead of [...]

No respite from permafrost-thaw impacts in absence of a global tipping point

Jan Nitzbon, Thomas Schneider von Deimling, Mehriban Aliyeva, et al.

Published: 2023-09-25
Subjects: Biogeochemistry, Climate, Earth Sciences, Geomorphology, Hydrology, Oceanography and Atmospheric Sciences and Meteorology, Physical Sciences and Mathematics

Arctic permafrost, the largest non-seasonal component of Earth’s cryosphere, contains a significant climate-sensitive carbon pool. Its potential for loss due to climatic changes leading to a global tipping point, where thawing accelerates with disproportionate impacts, remains debated. Here, we provide an integrative perspective on this question, building on a cross-disciplinary meta-analysis of [...]

Global groundwater system archetypes identify predominant patterns in socioeconomic, ecological, and Earth system functions of groundwater

Xander Huggins, Tom Gleeson, Karen G. Villholth, et al.

Subjects: Hydrology, Other Civil and Environmental Engineering, Physical and Environmental Geography, Spatial Science, Sustainability, Water Resource Management

Groundwater is a dynamic component of the global water cycle that performs important social, economic, ecological, and Earth system functions. Identifying the patterns and relationships between groundwater’s diverse functions can provide important insights to aid framework, model, and theory development on interactions between groundwater and its connected systems and can help generate [...]

Continental scale hydrostratigraphy: comparing geologically informed data products to analytical solutions

Jackson Swilley, Danielle Tijerina-Kreuzer, Hoang Tran, et al.

Published: 2023-09-12
Subjects: Civil and Environmental Engineering, Geology, Hydrology

This study synthesizes two different methods for estimating hydraulic conductivity (K) at large scales. We derive analytical approaches that estimate K and apply them to the contiguous US. We then compare these analytical approaches to three-dimensional, national gridded K data products and three transmissivity (T) data products developed from publicly available sources. We evaluate these data [...]

High Accuracy Estimation and Validation of InSAR-derived Surface Displacements at Temperate Raised Peatlands

Alexis Hrysiewicz, Jennifer Williamson, Chris D. Evans, et al.

Published: 2023-09-03
Subjects: Geophysics and Seismology, Hydrology, Soil Science

Peatland surface motion derived from satellite-based Interferometry of Synthetic Aperture Radar (InSAR) is potentially a proxy for groundwater level variations and greenhouse gas emissions from peat soils. Ground validation of these motions at equivalent temporal resolution and accuracy has proven problematic because of limitations of traditional surveying methods. Since 2019, peat surface motion [...]

Machine Learning Photogrammetric Analysis of Images Provides a Scalable Approach to Study Riverbed Grain Size Distributions

Peter Regier, Yunxiang Chen, Kyongho Son, et al.

Published: 2023-09-01
Subjects: Earth Sciences, Geomorphology, Hydrology

The distribution of sediment grain size in streams and rivers is often quantified by the median grain size (d50), a key metric for understanding and predicting hydrologic and biogeochemical function of streams and rivers. Manual methods to measure d50 are time-consuming and ignore larger grains, while model-based methods to estimate d50 often over-generalize basin characteristics, and therefore [...]

A Contemporary Systematic Review of Cyberinfrastructure Systems and Applications for Flood and Drought Data Analytics and Communication

Hydrometeorological disasters, including floods and droughts, have intensified in both frequency and severity in recent years. This trend underscores the critical role of timely monitoring, accurate forecasting, and effective warning systems in facilitating proactive responses. Today's information systems offer a vast and intricate mesh of data, encompassing satellite imagery, meteorological [...]

imc-precip-iso: Open monthly stable isotope data of precipitation over the Indonesian Maritime Continent

Stable isotopes, $\delta^2$H, $\delta^{18}$O, and d-excess, are valuable tools as natural tracers of diffusion processes and phase changes in the global hydroclimatological cycle. The Indonesian Maritime Continent (IMC) is an archipelago area surrounded by very warm waters which induce convective activities as the primary heat source driving global atmospheric circulation. Given the central role [...]

Physically based Probabilistic Rainfall Intensity-Duration (ID) Thresholds for Runoff-Generated Debris Flows

Oliver Francis, Hui Tang, Martino Bernard

Published: 2023-07-21
Subjects: Earth Sciences, Geology, Geomorphology, Hydrology

Runoff-generated debris flows are common hazards in mountainous regions, causing millions of dollars lost and hundreds of casualties yearly. Early warning systems based on rainfall thresholds have been implemented to reduce the impact of these hazards. These thresholds tend to be based on short monitoring periods, which cannot fully capture the varying responses of catchments to rainfall. As a [...]

Subsurface processes are a driving factor behind some surface processes in permafrost regions, but multiple geophysical techniques are needed to reliably constrain the strength, water saturation, and ice content of permafrost across these heterogeneous regions. This research investigates the spatial variability of permafrost in undisturbed tundra and the permafrost degradation in disturbed tundra [...]

An Artificial Neural Network to Estimate the Foliar and Ground Cover Input Variables of the Rangeland Hydrology and Erosion Model

Models like the Rangeland Hydrology and Erosion Model (RHEM) are useful for estimating soil erosion, however, they rely on input parameters that are sometimes difficult or expensive to measure. Specifically, RHEM requires information about foliar and ground cover fractions that generally must be measured in situ, which makes it difficult to use models like RHEM to produce erosion or soil risk [...]

Overexploitation of groundwater threatens groundwater-bound aquatic and terrestrial biodiversity and ecosystem stability, underscoring the need to devise appropriate mitigation strategies.
