GODEEEP-hydro: Historical and projected power system ready hydropower data for the United States
Published: 2025-01-08
Subjects: Hydrology, Power and Energy
Hydropower is a critical electricity resource in the United States which, in addition to renewable and carbon-free electricity generation, provides valuable ancillary grid services, and supports the integration of wind and solar resources. Despite its value to an increasingly decarbonized grid, there are very few comprehensive datasets available from which to study both historical and future [...]
Seasonal compound renewable energy droughts in the Unites States
Published: 2025-01-07
Subjects: Hydrology, Oil, Gas, and Energy, Power and Energy
Variable renewable energy (VRE) droughts are periods of low renewable electricity production due to natural variability in the weather and climate. These compound renewable energy droughts occur when two or more (typically wind and solar) generation sources are in low availability conditions at the same time. Compound wind and solar droughts are most commonly studied at the hourly and daily [...]
Interpretability on agile machine learning models for hydrological predictions: A case study in the mega-disaster in Rio Grande do Sul, Brazil, in May 4 2024
Published: 2024-12-30
Subjects: Hydrology
In May 2024, the region of the Rio Grande do Sul state experienced one of the worst floods in Brazilian history, affecting millions and causing severe damage to infrastructure. This study applies an agile hydrological forecasting approach using methods from traditional time-series models, such as ARIMA and SARIMA, and machine learning (ML) models, such as ElasticNet and LASSO. Data from [...]
Improved Streamflow Simulations in Hydrologically Diverse Basins using Physically Informed Deep Learning Models
Published: 2024-12-23
Subjects: Civil Engineering, Engineering, Hydrology
Physically informed deep learning models, especially Long Short-Term Memory (LSTM) networks, have shown promise in large-scale streamflow simulations. However, an in-depth understanding of the relative contribution of physical information in deep learning models has been missing. Using a large-sample testbed of 220 catchments in hydrologically diverse regions of the Indian subcontinent, we [...]
A Conversational Intelligent Assistant for Enhanced Operational Support in Floodplain Management with Multimodal Data

Subjects: Artificial Intelligence and Robotics, Civil and Environmental Engineering, Computer Sciences, Databases and Information Systems, Earth Sciences, Environmental Engineering, Environmental Sciences, Environmental Studies, Hydraulic Engineering, Hydrology, Water Resource Management
Floodplain management is crucial for mitigating flood risks and enhancing community resilience, yet floodplain managers often face significant challenges, including the complexity of data analysis, regulatory compliance, and effective communication with diverse stakeholders. This study introduces Floodplain Manager AI, an innovative artificial intelligence (AI) based virtual assistant designed to [...]
Groundwater connected art: practicing arts-based research to enrich how hydrogeology engages people, place and other disciplines
Published: 2024-12-12
Subjects: Environmental Studies, Hydrology, Other Geography
Groundwater depletion, contamination, and governance challenges persist despite decades of groundwater research. Scientific methods are crucial yet seem insufficient to inspire the deep emotional and cultural connections needed for real change – groundwater challenges and opportunities are not reaching enough hearts and minds. This article calls for a bold shift: integrating arts-based research [...]
Functional regression for space-time prediction of precipitation-induced shallow landslides in South Tyrol, Italy
Published: 2024-12-10
Subjects: Applied Statistics, Environmental Indicators and Impact Assessment, Environmental Monitoring, Geology, Geomorphology, Hydrology, Multivariate Analysis, Statistical Models
Shallow landslides are geomorphic hazards in mountainous terrains across the globe. Their occurrence can be attributed to the interplay of static and dynamic landslide controls. In previous studies, data-driven approaches have been employed to model shallow landslides on a regional scale, focusing on analyzing the spatial aspects and time-varying conditions separately. Still, the joint assessment [...]
Disappearance of Homo floresiensis from Liang Bua alongside seasonal aridification of Flores 61,000-47,000 years ago
Published: 2024-12-10
Subjects: Atmospheric Sciences, Climate, Environmental Indicators and Impact Assessment, Fresh Water Studies, Geochemistry, Hydrology, Paleobiology, Physical Sciences and Mathematics, Speleology
The cause of the disappearance of the primitive hominin, Homo floresiensis, from the Indonesian island of Flores ~50,000 years ago is a key question in palaeoanthropology. The potential roles of human agency and climate change continue to be debated, but the history of freshwater availability critical to survival at the type locality, Liang Bua, remains unknown. Although speleothem 18O is used [...]
Tracking Drought Impacts from Texts: Towards AI-Assisted Drought Impact Detection

Subjects: Artificial Intelligence and Robotics, Computer Sciences, Earth Sciences, Environmental Indicators and Impact Assessment, Environmental Sciences, Hydrology
Drought is recognized for its extensive and varied impacts. Based on the drought-related textual datasets from the National Drought Mitigation Center, our research applies advanced artificial intelligence techniques, including deep learning and natural language processing, to enhance the monitoring of multifaceted drought impacts in the United States. This study also delves into predicting [...]
Modelling glacier mass balance and runoff in the Kaskawulsh River headwaters of southwest Yukon, Canada, 1980-2022
Published: 2024-11-30
Subjects: Glaciology, Hydrology
The highly-glacierized headwaters of the Kaskawulsh River are home to 9% of all glacier ice in Yukon, Canada, have been losing glacier mass at regionally representative rates, and were the source of a sudden meltwater-rerouting event in 2016 that has had significant downstream consequences. We use an enhanced temperature-index melt model driven by downscaled and bias-corrected climate reanalysis [...]
A decadal survey of the near-surface seismic velocity response to hydrological variations in Utah, United States
Published: 2024-11-21
Subjects: Environmental Monitoring, Geophysics and Seismology, Hydrology
Ongoing climate change leads to an increase in prolonged drought and severe weather events in the United States, particularly pronounced in semi-arid regions such as the western United States. It could have lasting social and environmental impacts. Continuous monitoring of near-surface hydrological processes and groundwater resources will provide helpful information for effective water resource [...]

Controls on coastal saline groundwater across North America
Published: 2024-10-18
Subjects: Hydrology
Groundwater is crucial to sustaining coastal freshwater needs. About 32 million people in the coastal USA rely on groundwater as their primary water source. With rapidly growing coastal communities and increasing demands for fresh groundwater, understanding controls of continental-scale coastal groundwater salinity is critical.
