Wastewaters co-produced with shale gas drive slight regional salinization of groundwater
Published: 2024-04-04
Subjects: Geochemistry, Oil, Gas, and Energy, Water Resource Management
While unconventional oil and gas (UOG) development is changing the world economy, processes that are used during UOG development such as high-volume hydraulic fracturing (“fracking”) have been linked with water contamination. Water quality risks include leaks of gas and salty fluids (brines) that are co-produced at wellpads. Identifying the cause of contamination is difficult, however, because [...]
Estimating irrigation water use from remotely sensed evapotranspiration data: Accuracy and uncertainties at field, water right, and regional scales
Published: 2024-02-29
Subjects: Earth Sciences, Environmental Monitoring, Environmental Sciences, Hydrology, Sustainability, Water Resource Management
Irrigated agriculture is the dominant user 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 intensively [...]

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 [...]
PHOTOMOB: AUTOMATED GIS METHOD FOR ESTIMATION OF FRACTIONAL GRAIN DYNAMICS IN GRAVEL BED RIVERS. PART 1: GRAIN SIZE
Published: 2023-12-06
Subjects: Earth Sciences, Environmental Monitoring, Geomorphology, Hydrology, Sedimentology, Water Resource Management
Particle entrainment intensity is spatially and temporally variable, making it a complex phenomenon to measure. This paper is the first of a pair, in which we present an automated image processing procedure (PhotoMOB) for monitoring the mobility/stability of gravel river beds. The method is based on local comparison of the shape of the grains identified at the same coordinates between successive [...]

Bed mobility and stability are spatially and temporally variable, making it a complex phenomenon to study. This paper is the second of a pair, in which we present an automated image processing procedure for monitoring the mobility/stability of gravel river beds. The method is based on local comparison of the shape of the grains identified at the same coordinates between successive photos to [...]
UMIS: An Integrated Cyberinfrastructure System for Water Quality Resources in the Upper Mississippi River Basin

The Upper Mississippi Information System (UMIS) is a cyberinfrastructure framework designed to support large-scale real-time water quality data integration, analysis, and visualization for the Upper Mississippi River Basin (UMRB). UMIS is intended to directly address three of the Grand Challenges for Engineering including: 1) understanding access to clean drinking water, 2) management of the [...]
Looking upstream: analyzing the protection of the drainage area of Amazon rivers
Published: 2023-11-13
Subjects: Earth Sciences, Environmental Indicators and Impact Assessment, Environmental Sciences, Hydrology, Sustainability, Water Resource Management
In the Amazon, aquatic ecosystems provide essential ecosystem services, including transportation, food, and livelihoods for millions of species. Land use changes and management impact these ecosystem services, and these impacts are not limited to the specific areas where they occur but propagate downstream along the drainage network. However, assessment of the accumulated human footprint upstream [...]
A Deep Learning framework to map riverbed sand mining budgets in large tropical deltas
Published: 2023-10-20
Subjects: Computer Sciences, Earth Sciences, Environmental Education, Environmental Health and Protection, Environmental Monitoring, Environmental Sciences, Natural Resource Economics, Natural Resources and Conservation, Natural Resources Management and Policy, Other Environmental Sciences, Planetary Geomorphology, Planetary Sedimentology, Sustainability, Water Resource Management
Rapid urbanization has dramatically increased the demand for river sand, leading to soaring sand extraction rates that often exceed natural replenishment in many rivers globally. However, our understanding of the geomorphic and social-ecological impacts arising from Sand Mining (SM) remains limited, primarily due to insufficient data on sand extraction rates. Conventionally, bathymetry surveys [...]
Mapping the Landscape of Water and Society Research: Promising Combinations of Compatible and Complementary Disciplines

Coupled human-water systems (CHWS) are diverse and have been studied across a wide variety of disciplines. Integrating multiple disciplinary perspectives on CHWS provides a comprehensive and actionable understanding of these complex systems. While interdisciplinary integration has often remained elusive, specific combinations of disciplines might be comparably easier to integrate (compatible) [...]

Groundwater is a dynamic component of the global water cycle with important social, economic, ecological, and Earth system functions. We present a new global classification and mapping of groundwater systems, which we call groundwaterscapes, that represent predominant configurations of large-scale groundwater system functions. We identify 18 groundwaterscapes, which offer a new lens to [...]
