Automated Levee Detection in Digital Elevation Models
Published: 2026-03-04
Subjects: Geomorphology
Current flood risk models applied at national and global scales do not---or only partially---take levees into account, resulting in inaccurate flood inundation maps. While levees are important assets in natural hazard risk assessments, accurate information in the public domain about the location and height of these embankments is often missing. Remote sensing data---such as global digital [...]
High-resolution interactive global flood forecast for past, present, and future
Published: 2026-03-04
Subjects: Engineering
Globally operating modelling approaches for flood dynamics have shown significant increases in usage, quality and availability in recent years. Flood modelling at global scale stretches the computational demand, due to combinations of spatial scale and resolution, limiting to static pre-computed maps and prohibiting interactivity. Particular high-resolution global models are only available as [...]
Human Civilization will Collapse (High Confidence): A Compendium of Relevant Biophysical, Political, Economic, Military, Health, and Psychological Information on Climate Change
Published: 2024-01-11
Subjects: Life Sciences, Physical Sciences and Mathematics, Social and Behavioral Sciences
Human civilization will not collapse from the direct effects of climate change, but rather from the secondary effects of crop failures, infectious diseases, and armed conflict. The root cause of the climate crisis is the Earth’s energy imbalance: more energy is arriving at the Earth from the sun than is being radiated back out into space. This is occurring because we have been cutting down [...]
Feedback-Controlled Linear Actuator System to Simulate Laboratory Analogs of Landslides
Published: 2026-07-23
Subjects: Civil Engineering, Earth Sciences, Engineering, Geomorphology, Geophysics and Seismology, Geotechnical Engineering, Physical Sciences and Mathematics, Physics, Statistical, Nonlinear, and Soft Matter Physics
This study describes a scientific apparatus that induces granular flow by tilting an acrylic sample container under user-prescribed constant angular velocity and acceleration profiles. The system consists of a transparent sample container mounted within a motorized frame driven by a linear actuator that we control using pulse-width modulation with feed-forward compensation. Additional components [...]
Hydrological modeling in a highly urbanized watershed using explainable machine learning and sub-hourly data: A case study in the city of Sao Paulo, Brazil
Published: 2026-03-04
Subjects: Engineering
Hydrological modeling of urbanized watersheds is a highly challenging task due to the complexity and non-linearity of the rainfall-runoff relationship in these areas. Many data-driven models have been proposed in the literature to address this problem. However, in this field, there is a need not only for performance but also for explainability and comprehension of the impacts of [...]
fasterRaster: GIS in R using GRASS for large vectors and rasters
Published: 2025-10-17
Subjects: Geomorphology, Hydrology, Other Earth Sciences, Other Environmental Sciences
Within the R ecosystem, packages like terra and sf are the go-to solutions for most geospatial analyses, yet can struggle with large rasters and vectors. The Geographic Resources Analysis Support System, or GRASS, offers solutions that are often more efficient for large data. However, using GRASS through R requires users to become familiar with GRASS-specific syntax and data constructs. The [...]
Parcel-Level Deforestation Hazard Rates in the Paraguayan Chaco: A Multi-Scale Empirical Analysis of Annual Clearing Dynamics on Large Cattle Ranches
Published: 2026-10-04
Subjects: Geographic Information Sciences, Natural Resources and Conservation, Natural Resources Management and Policy, Other Environmental Sciences, Physical and Environmental Geography, Remote Sensing
Cattle ranch expansion across the Paraguayan Chaco generates parcel-level clearing rates that appear inconsistent with regional deforestation statistics, raising concerns that REDD+ baselines constructed from proxy parcels overstate forest loss (a baseline over-crediting debate that turns on denominator consistency between parcel hazard and regional flows). Because parcels undergoing active [...]
Transient liquid- and solid-dominated inflation of an upper crustal magma chamber: insights from the Carlingford Complex (Ireland)
Published: 2026-03-18
Subjects: Earth Sciences, Geochemistry, Geology, Volcanology
Layered intrusions are the crystallised remnants of magma reservoirs and preserve a detailed record of magma storage, differentiation, and recharge processes in the upper crust. Their assembly is commonly categorised into two end-member emplacement regimes: long-lived liquid-dominated magma chambers, and incrementally assembled crystal-rich mush systems. These end-members are often presented as [...]
Measured or assumed? Regulatory defaults, ownership, and the measurement content of the U.S. greenhouse gas inventory
Published: 2026-09-04
Subjects: Environmental Studies, Nature and Society Relations, Risk Analysis
Municipal solid waste landfills are the third-largest anthropogenic source of methane in the United States, and the national inventory for this source is assembled almost entirely from facility self-reports filed under Subpart HH of the Greenhouse Gas Reporting Program (GHGRP). Airborne and satellite surveys estimate actual emissions at 1.4 to 2.7 times reported levels, but remote sensing alone [...]
The Permian–Triassic transition in Türkiye: New insights and 3D outcrop models for accessible, reproducible and sustainable fieldwork
Published: 2025-08-21
Subjects: Biodiversity, Earth Sciences
The Permian–Triassic transition is characterised by major environmental changes and the largest known mass extinction event in the Phanerozoic. However, successions with a relatively complete sedimentological and palaeontological record across the Permian–Triassic are limited to a few well-known sections. The Antalya and Aladağ Nappes in south-western Türkiye provide extensive outcrops of the [...]
WITHDRAWN: Sustaining Life on the Fault Line: Women’s Social Reproduction and Grassroots Disaster Governance in Yogyakarta, Indonesia

Water Health: Testing and Determining Health of Local Bodies of Water
Published: 2026-03-31
Subjects: Ecology and Evolutionary Biology
Ponds and rivers represent distinct aquatic ecosystems characterized by significant differences in size, flow, and water quality metrics through pH, salinity, total dissolved solids (TDS), specific gravity, temperature, electric current, and oxidation-reduction potential (ORP). While general metrics for assessing pond health are well-established, regional tolerance ranges can vary from commonly [...]
Dataset of DInSAR wrapped phase signals for AI-based automated detection and classification of mass movements
Published: 2026-03-26
Subjects: Earth Sciences, Environmental Monitoring, Environmental Sciences, Geology, Geomorphology, Physical Sciences and Mathematics
With the growing use of Artificial Intelligence (AI) in remote sensing of mass movements, available datasets for model training and validation are increasingly needed. Although Differential Synthetic Aperture Radar Interferometry (DInSAR) is a widely used technique for studying mass movements, wrapped interferograms remain less exploited, and the importance of geomorphological expertise in their [...]

Identification of Stress-Resilient Maize Progenies under Drought and Low Nitrogen in West Africa Using Genotype × Environment Analysis and Multi-Trait Selection Indices
Published: 2026-05-16
Subjects: Agriculture
Maize productivity in West Africa is severely constrained by recurrent drought and low soil nitrogen availability, which results in strong environmental heterogeneity and complex genotype × environment interactions (G×E). Identifying breeding materials that combine productivity, stress resilience, and stability therefore requires analytical approaches that integrate multi-trait and [...]
