Quantifying water availability in basins holding the majority of global lithium resources
Published: 2024-04-24
Subjects: Earth Sciences, Hydrology, Physical Sciences and Mathematics
Demand for lithium is expected to increase by as much as 40 times over the coming decades. More than half the world’s lithium resources are found in brine aquifers at the intersection of Chile, Argentina, and Bolivia. As lithium exploration increases, accurate estimates of water availability are critical for water management decisions, particularly in this region home to communities and [...]
Evaluation of the METRIC and TSEB remote sensing evapotranspiration models in the floodplain area of the Thaya and Morava Rivers
Published: 2024-04-24
Subjects: Hydrology, Other Earth Sciences, Other Forestry and Forest Sciences
Study region: Floodplain ecosystem region at the confluence of the Morava and Thaya Rivers, Czech Republic. Study focus: Accurate determination of actual evapotranspiration (ETa) is essential for understanding surface hydrological conditions. The aim of this study was to evaluate two remote sensing models, METRIC and TSEB, for estimating ETa and energy fluxes in two ecosystems using the eddy [...]
Limited role of discharge in global river plastic transport
Published: 2024-04-23
Subjects: Hydrology, Sustainability, Water Resource Management
River plastic transport has been assumed to be driven by river discharge, although observational data does often not support this. We propose a new perspective that describes plastic transport as function of plastic availability and transport capacity. Plastic transport is under most circumstances driven by plastic availability, which is largely disconnected from river discharge. However, when [...]
Urbanization vs climate drivers: investigating changes in fluvial floods in Poland
Published: 2024-04-11
Subjects: Hydrology
Fluvial floods are one of the most severe natural hazards. Changes in flood behaviour result from an interplay of climatic and human factors. Urbanization, with increasing land imperviousness, is the most critical human factor. This study investigates the effect of urbanization vs climate drivers on river floods in Poland, using the paired catchment approach. We used daily river flow data from [...]
Pleistocene shifts in Great Basin hydroclimate seasonality govern the formation of lithium-rich paleolake deposits
Published: 2024-04-10
Subjects: Earth Sciences, Hydrology, Oceanography and Atmospheric Sciences and Meteorology, Paleobiology, Sedimentology
Southwestern North America is currently experiencing a multidecadal megadrought, with severe consequences for water resources. However, significant uncertainty remains about how precipitation will change in the 21st century in this semi-arid region. Paleoclimatic records are essential for both contextualizing current change, and for helping constrain the sensitivity of regional hydroclimate to [...]
EStreams: An Integrated Dataset and Catalogue of Streamflow, Hydro-Climatic Variables and Landscape Descriptors for Europe
Published: 2024-03-02
Subjects: Earth Sciences, Environmental Sciences, Hydrology
Global hydrology datasets have become increasingly available, contributing to important scientific advances. However, in Europe, only a few such datasets were published and they only capture a fraction of the wealth of information national data providers have. We present “EStreams”, an extensive catalogue of openly available stream records and a dataset of hydro-climatic variables and landscape [...]
Estimating irrigation water use from remotely sensed evapotranspiration data: Accuracy and uncertainties across spatial scales
Published: 2024-02-29
Subjects: Earth Sciences, Environmental Monitoring, Environmental Sciences, Hydrology, Sustainability, Water Resource Management
Irrigated agriculture is the dominant use of water globally, but most water withdrawals are not monitored or reported. As a result, it is largely unknown when, where, and how much water is used for irrigation. Here, we evaluated the ability of remotely sensed evapotranspiration (ET) data, integrated with other datasets, to calculate irrigation water withdrawals and applications in an [...]

The objective of this paper is to present the initial illustration of a cyberinfrastructure named the River MORPhology Information System (RIMORPHIS) that addresses the current limitations related to river morphology data and tools. A new specification for data and semantics on river morphology datasets has been developed to support the web-based platform for discovering and visualization of [...]
River Floodplains, Organic Carbon, and Paleoclimate: How River Dynamics Impart Biases in the Biogeochemical Climate Record of Terrestrial Landscapes
Published: 2024-01-29
Subjects: Earth Sciences, Geochemistry, Geomorphology, Hydrology, Physical Sciences and Mathematics, Sedimentology, Stratigraphy
River floodplains can be both sources and sinks for organic carbon. In the sedimentary record, geochemical signatures of terrestrial water availability record climate and ecology along river corridors in deep time. However, paleoenvironmental reconstructions are often confounded by the complex dynamics of organic carbon residence, entrainment, and deposition in a fluvial system. As alluvial [...]
Wealth over Woe: global biases in hydro-hazard research
Published: 2024-01-12
Subjects: Computer Sciences, Hydrology, Nature and Society Relations, Sustainability
Floods, droughts, and rainfall-induced landslides are hydro-geomorphic hazards that affect millions of people every year. Anticipation, mitigation, and adaptation to these hazards is increasingly outpaced by their changing magnitude and frequency due to climate change. A key question for society is whether the research we pursue has the potential to address knowledge gaps and to reduce potential [...]
Open-source approach for reproducible substrate mapping using semantic segmentation on recreation-grade side scan sonar datasets
Published: 2023-12-21
Subjects: Analysis, Artificial Intelligence and Robotics, Databases and Information Systems, Environmental Monitoring, Hydrology, Natural Resources and Conservation, Numerical Analysis and Computation, Numerical Analysis and Scientific Computing, Programming Languages and Compilers, Software Engineering, Terrestrial and Aquatic Ecology, Water Resource Management
Knowledge of the variation and distribution of substrates at large spatial extents in aquatic systems, particularly rivers, is severely lacking, impeding species conservation and ecosystem restoration efforts. Air and space-borne remote sensing important for terrestrial and atmospheric measurements are limited in benthic environments due to river stage, turbidity, and canopy cover, requiring [...]

Never train an LSTM on a single basin
Published: 2023-12-05
Subjects: Artificial Intelligence and Robotics, Computer Sciences, Earth Sciences, Hydrology, Physical Sciences and Mathematics
Machine learning (ML) has an increasing role in the hydrological sciences, and in particular, certain types of time series modeling strategies are popular for rainfall-runoff modeling. A large majority of studies that use this type of model do not follow best practices, and there is one mistake in particular that is very common: training deep learning models on small, homogeneous data sets (i.e., [...]
