Automated GIS-Based Hydrological Modeling Framework for Flood Hydrograph Estimation in Ungauged Mediterranean Catchments: A Case Study of Sicily
Published: 2026-06-06
Subjects: Civil and Environmental Engineering, Engineering, Environmental Engineering, Hydraulic Engineering
The estimation of design flood hydrographs in ungauged Mediterranean catchments remains a persistent challenge for hydrological engineering, flood hazard assessment, and territorial risk planning. The absence of discharge observations, coupled with the high temporal concentration of precipitation and the marked geomorphological variability of small basins, renders conventional calibration-based [...]
A Fibonacci-Like Propagation Graph for Infiltration and Internal Erosion in Heterogeneous Layered Soils
Published: 2026-06-06
Subjects: Geotechnical Engineering, Hydrology, Numerical Analysis and Scientific Computing, Soil Science
Infiltration and internal erosion in heterogeneous layered soils involve coupled flow, pressure build-up, and material degradation across preferential subsurface pathways. High-fidelity Richards-type simulators are physically detailed but can be too expensive for rapid scenario screening and Monte Carlo uncertainty propagation when hydraulic parameters are poorly constrained. We introduce a [...]

Solar radiation modification (SRM) is a proposed temporary intervention to limit global warming while mitigation efforts continue. Understanding its potential consequences for human and natural systems is essential for informed deliberations. We conducted a systematic review of the peer-reviewed literature on SRM impacts published through May 2024, identifying 289 studies, including 261 primary [...]
Spatially Distributed Land-Use Efficiency Assessment under SDG Indicator 11.3.1: The Case of Greater Manila Area, Philippines
Published: 2026-06-06
Subjects: Environmental Indicators and Impact Assessment, Environmental Monitoring, Environmental Sciences, Sustainability
Sustainable Development Goal (SDG) Indicator 11.3.1 assesses urban land-use efficiency (LUE) through the relationship between land consumption rate (LCR) and population growth rate (PGR), commonly expressed as LCRPGR. However, city-level implementation produces a single value that can mask where efficient or inefficient urban development occurs. This study develops and demonstrates a spatially [...]
ADMM-Guided Physics-Informed Deep Learning for Two-Dimensional Acoustic Impedance Inversion with Reweighted ℓ1 Sparse Regularization
Published: 2026-06-06
Subjects: Physical Sciences and Mathematics
Acoustic impedance inversion is ill-posed because post-stack seismic data are band-limited and noisy. Reweighted ℓ1 sparse inversion sharpens impedance boundaries but, applied trace by trace, ignores lateral geological continuity. We present a two-dimensional ADMM-guided physics-informed neural framework in which a reweighted ℓ1 ADMM estimate (after He et al., 2022) serves as a physics prior for [...]
Exact solutions for ice flow across the no-slip to free-slip transition
Published: 2026-06-05
Subjects: Physical Sciences and Mathematics
The downhill flow of a viscous ice stream across a no-slip to free-slip transition remains elusive to exact solutions due to the existence of singularities. Here we replace the point-wise sharp transition by a functional dependency of parametrised horizontal length. Analytical solutions are found for the steady Navier-Stokes flow with Newtonian properties. Our solution remains smooth and [...]
Two decades of kilometer-scale daily PM2.5 from satellite observations and machine learning reveal geographically diverging exposure in Ghana
Published: 2026-06-05
Subjects: Artificial Intelligence and Robotics, Atmospheric Sciences, Civil and Environmental Engineering, Earth Sciences, Engineering, Environmental Engineering, Environmental Monitoring, Environmental Public Health, Environmental Sciences, Geographic Information Sciences, Geography, Oceanography and Atmospheric Sciences and Meteorology, Other Earth Sciences, Remote Sensing, Spatial Science
Exposure to fine particulate matter (PM2.5) is a major contributor to global burden of disease, yet air quality data remain sparse in many low- and middle-income countries, limiting nationwide monitoring and effective policy development. We address this gap by developing a high-resolution gridded (1 km × 1 km) dataset for daily surface PM2.5 concentrations in Ghana from 2005 to 2025 by training [...]
Beyond Techno-Centered Decarbonization Roadmaps: Designing Demand-Side Pathways for Sustainable Mobility
Published: 2026-06-05
Subjects: Environmental Studies
Decarbonization roadmaps for the automobile sector predominantly rely on supply-side improvements and electrification, yet their ability to deliver the required environmental reductions remains uncertain. This study introduces the Demand-Side Decomposition Analysis framework, which consistently integrates demand-side mitigation into a parametrized life cycle assessment of the automobile value [...]
Ecosystem accounting for social-ecological policy: an applied ecological economics research agenda from Guatemala
Published: 2026-06-05
Subjects: Environmental Studies
Economy and ecology are inseparable since economic decisions affect the natural systems that sustain them. Conventional economics still treats this dependence as an externality to be corrected through prices, even as ecosystems lose resilience and the economy presses against planetary boundaries. Ecological economics offers a more adequate framework, one that situates the economy within a finite [...]
Impacts of short-term weather on communicable enteric infectious diseases in western Europe: A case study of the Republic of Ireland, 2009–2020
Published: 2026-06-05
Subjects: Public Health
The incidence of sporadic enteric infections at temperate latitudes, including much of western Europe, vary seasonally, and as such are forecasted to shift in response to global climate changes. Understanding the associations between weather patterns and infection incidence is crucial to focus future surveillance efforts and minimise disease transmission. Accordingly, the relationship between [...]
Empirical Relationships Between Ground Motion Intensities and JMA Seismic Intensity Scale
Published: 2026-06-05
Subjects: Physical Sciences and Mathematics
There is a growing appetite for parametric Japanese earthquake insurance products that use Japanese Meteorological Agency seismic intensity, IJMA, triggers. However, most earthquake risk models used to price these contracts do not compute IJMA directly, instead relying on conversions that introduce additional basis risk. Here, we present empirical parameterisations of IJMA as a function of all [...]
Colonial Hydrologies and Local Ecologies: An Ethnographic Study of the Beas River Region in Punjab, Pakistan
Published: 2026-06-04
Subjects: Environmental Studies
The disappearance of the Beas River in Pakistan's Punjab, completed by a natural migration of the river's channels between 1750 and 1800, predates colonial hydraulic intervention, the partition of 1947, and the Indus Water Treaty of 1960. Each successive political and infrastructure development has not caused the river to disappear, but has gradually formalized and deepened it, removing any [...]

Climate overshoot and the insurability frontier: peak stress, domestic capacity, and market retreat risk
Published: 2026-06-04
Subjects: Environmental Sciences, Environmental Studies, Geography, Oceanography and Atmospheric Sciences and Meteorology, Planetary Sciences
Climate overshoot can create mid-century peaks in climate stress before end-century temperatures stabilize, but its implications for insurance availability remain poorly understood. We assess subnational insurance market exit risk under overshoot across 1,590 first-order administrative regions in 88 countries, covering 4.54 billion people. Combining ADM1-level multi-hazard climate stress, an [...]
Deciphering the morphology of turbiditic lobe bodies according to hierarchy and system size
Published: 2026-06-04
Subjects: Applied Statistics, Earth Sciences, Planetary Sciences, Planetary Sedimentology, Statistics and Probability
Turbiditic lobe bodies (LBs) are the ultimate deposits of source-to-sink systems. Their geometry and architecture vary with depositional environment (marine vs. lacustrine), hierarchy (lobe elements, lobes, lobe complexes), system size (large vs. small) and topographic confinement. Constraining these variations is useful for characterizing the dispersion of sediments, carbon, nutrients, and [...]
