Computation to Choose a Future: Planetary Stewardship in the Age of AI
Published: 2025-11-26
Subjects: Engineering, Physical Sciences and Mathematics
The accelerating transformations of the Anthropocene demand governance systems capable of anticipating and steering complex, nonlinear Earth-system dynamics. Existing models optimize for likely trajectories rather than exploring a broader set of futures. This commentary introduces the concept of Computational Foresight (CF): an integrative framework combining artificial intelligence, simulation, [...]
Barrier vulnerability following outwash: A balance of overwash and dune gap recovery
Published: 2025-11-23
Subjects: Engineering, Physical Sciences and Mathematics
Existing barrier evolution models only simulate storm impacts from landward-driven flows (overwash), neglecting the impacts of seaward-directed flows (outwash). Here, we modify an existing model to incorporate outwash processes. We find that outwash enhances barrier vulnerability (the tendency to drown) over decadal timescales by scarring the island interior, creating lower, narrower landforms. [...]

Attention-Based Deep Learning for Runoff Forecasting: Evaluating the Temporal Fusion Transformer Against Traditional Machine Learning Models
Published: 2025-11-20
Subjects: Engineering, Life Sciences
Reliable runoff forecasting is critical for water management and flood preparedness in Nepal’s steep, data-scarce catchments. Traditional models such as SWAT provide process insights but demand extensive calibration and detailed inputs often unavailable in such regions. Recent advances in attentionbased deep learning offer new opportunities to capture temporal dependencies with improved [...]
Thermal Power and Climate Change: A Data-Driven Analysis of Cause and Effect, 1800-2100
Published: 2025-11-20
Subjects: Education, Engineering, Life Sciences, Physical Sciences and Mathematics, Social and Behavioral Sciences
Since 2020, global politics have shifted sharply to the right—nowhere more visibly than in Europe and the United States. By 2024, this rightward turn in the U.S. culminated in open climate-change denial, the defunding of clean-energy initiatives, and a widespread rejection of scientific evidence. Major domestic and international institutions—NOAA, NASA, the U.S. Weather Bureau, EPA, USDA, FDA, [...]

Developing an Open-access Telegram Bot for Automated, estimation and IA-based interpreted of OpenQuake Ground-Motion intensity measures
Published: 2025-11-13
Subjects: Education, Engineering, Life Sciences, Physical Sciences and Mathematics
The prediction of Intensity Measures (IMs) using Ground-Motion Models (GMMs) is a fundamental component of seismic hazard assessment. However, the best estimation of IMs traditionally requires specialised searchers, programming expertise, and the manual sourcing of regression coefficients. This complexity creates a significant barrier to rapid, scenario-based analysis for engineers, researchers, [...]
Multi-Agent Geophysical AI Workflow for Automated Reservoir Characterization
Published: 2025-11-06
Subjects: Artificial Intelligence and Robotics, Computational Engineering, Computer Sciences, Earth Sciences, Engineering, Geophysics and Seismology
Traditional geophysical workflows like reservoir characterization are driven in a collaborative manner where teams of geoscientists share their individual analyses to inform key decisions made by executives. However, these workflows are repetitive, time-consuming, prone to human error, and introduce subjective bias. While researchers have used automation to address these limitations via deep [...]
Emerging AI Solutions for Hazardous PET Waste in Marine Environments: A Review of Underexplored Paradigms
Published: 2025-11-05
Subjects: Engineering
Polyethylene terephthalate (PET) pollution, due to its persistence, chemical recalcitrance, and widespread usage, represents a growing hazard to marine ecosystems. Its accumulation contributes to long-term ecotoxicological risks, food chain contamination, and environmental degradation. Addressing this challenge necessitates the adoption of scalable, efficient, and intelligent strategies for [...]

Fallowed Heat Island: High surface temperature from fallowed agricultural lands increases nearby water demand and reduces crop yield.
Published: 2025-10-25
Subjects: Engineering, Life Sciences
Agricultural land fallowing is a practice of temporarily idling farmlands to maximize soil water storage, restore plant nutrients, and minimize soil erosion hazards. Despite the benefits of land fallowing, it remains unclear to what extent it affects nearby crop productivity. Here, we show that one such effect is through the fallowed heat island, a concept similar to urban heat island, whereby [...]
A Static Enthalpy Equilibrium Approach to the Stability of Saturated Sands (Version 2)
Published: 2025-10-25
Subjects: Civil and Environmental Engineering, Civil Engineering, Construction Engineering and Management, Earth Sciences, Engineering, Environmental Engineering, Geotechnical Engineering, Hydraulic Engineering, Mineral Physics, Physical Sciences and Mathematics, Sedimentology
This preprint presents a physical formulaton for the stability of saturated granular systems based on a static enthalpy equilibrium. The approach definnes equilibrium as the balance between the gravitationel potential of the granular framework and the hydraulic work of the pore water. From this energetic condition, the limit state and the transition between stable, metastable, and liquefied [...]
Aerial LiDAR Based, Source Resolved Methane Emissions Inventory: Permian Basin Case Study for Benchmarking U.S. Emissions
Published: 2025-10-24
Subjects: Engineering, Physical Sciences and Mathematics
Reducing methane emissions is one of the quickest ways to slow near-term warming, yet building accurate inventories to track progress towards reduction targets remains challenging. We present a 2024 source-resolved methane inventory for the Permian Basin built from quarterly aerial LiDAR scans that supports benchmarking and provides a scalable framework for operator-level OGMP 2.0 reporting. We [...]
Effects of cementation on the cyclic resistance of granular soils with presence of initial static shear stress
Published: 2025-10-23
Subjects: Engineering
In engineering applications such as non-invasive cementation beneath existing structures or naturally induced cementation around piles, cementation can develop in soils that have previously undergone initial static shear. However, the joint effect of cementation and initial static shear stress on subsequent cyclic loading behaviour remains largely uninvestigated, despite its crucial importance [...]
Climate as the Primary Moderator: Towards Context-Driven Design and Implementation of Vertical Greenery Systems for Stormwater Management

Subjects: Civil and Environmental Engineering, Engineering
Urbanisation intensifies stormwater management challenges by expanding impervious surfaces, increasing flood risk and degrading water quality. Vertical Greenery Systems (VGS) are increasingly promoted as nature-based solutions for space-constrained cities, yet their performance remains highly variable and context-dependent. This systematic review, conducted in accordance with PRISMA guidelines [...]
