Extraction and re-implementation of SWAT-Model calculations under the MAELIA platform in order to simulate the socio-environmental impacts of norms
Published: 2026-02-13
Subjects: Civil and Environmental Engineering
MAELIA (Multi-Agent for EnvironmentaL norms Impact Assesment) is an agent-based simulation platform designed to assess the impact of alternative water management policies at the watershed level. It simulates interactions between human activities (agricultural, domestic and industrial withdrawals, regulations of water uses) and ecological processes (crop growth, plant evapotranspiration and water [...]
A quantitative assessment of the reliability and feasibility of process-based urban stormwater quality models: Towards new evaluation criteria
Published: 2026-02-13
Subjects: Civil and Environmental Engineering
Hydrologic models have been increasingly used as a numerical tool to support urban stormwater management. Evaluation of modeling approaches helps identify the strength and weakness of a model to meet end-user requirements. However, traditional model evaluations only focus on the technical performance of a model, whereas very few studies have been conducted to quantitatively evaluate practical [...]
Aerosol from the Asian monsoon ubiquitous throughout the extratropical stratosphere
Published: 2026-02-12
Subjects: Physical Sciences and Mathematics
Asian summer monsoon (ASM) convection efficiently transports surface emissions into the upper troposphere, leading to the formation of the Asian tropopause aerosol layer (ATAL). The ATAL can affect Earth’s climate directly by scattering solar radiation and indirectly by cloud formation. Little is known about the global distribution of aerosol originating in the ASM, particularly in the [...]
Multiple-Well Monitoring Site Adjacent to the Midway- Sunset and Buena Vista Oil Fields, Kern County, California
Published: 2026-02-12
Subjects: Earth Sciences, Geochemistry, Geology, Hydrology, Physical Sciences and Mathematics
Groundwater quality in and around oil fields in the Southern San Joaquin Valley is of interest to many California residents that rely heavily on groundwater for domestic, commercial, and agricultural use. To help assess the effects of historical oil-field activities and natural geologic sources on groundwater near the southwest margins of the Kern County Groundwater Subbasin, a multiple-well [...]
A preliminary seismic catalog for the Mozambique Channel
Published: 2026-02-12
Subjects: Geophysics and Seismology, Tectonics and Structure
The Mozambique Channel is a 1,600-km long, 950 – 1,000-km wide deep-water arm of southwestern Indian Ocean, located between Mozambique and Madagascar Island. The channel hosts the offshore continuation of the East African Rift System, an active divergent plate boundary that has propagated from the African continent, across Mesozoic continental rifted margins, into Mesozoic oceanic lithosphere. [...]
Shifting the Paradigm: Redefining the Chronostratigraphy of the Triassic Rewan Group, Bowen Basin, Australia
Published: 2026-02-12
Subjects: Earth Sciences, Geology, Physical Sciences and Mathematics, Tectonics and Structure
The Triassic continental Rewan Group in the northern Bowen Basin, Queensland, Australia, consisting of the Sagittarius Sandstone and the Arcadia Formation, preserves a key record of terrestrial environments and faunas that have been assumed to document recovery following the end‑Permian mass extinction (EPME). The Rewan Group accumulated in a retroarc foreland basin during the Hunter–Bowen [...]
Scholte-wave Adjoint Tomography for Building Low-frequency, Offshore Shear-wave Velocity Models
Published: 2026-02-12
Subjects: Geophysics and Seismology
Field observations have shown that low-frequency (sub-1 Hz) Scholte waves retrieved from ocean-bottom node (OBN) data are strongly influenced by large-scale velocity heterogeneities such as salt bodies, underscoring their potential for offshore model building. However, procedures for translating this sensitivity into reliable subsur- face velocity models remains poorly understood. Motivated by [...]
Did Seattle go silent during the Superbowl?
Published: 2026-02-12
Subjects: Geophysics and Seismology
Large-scale cultural events such as sports games and music concerts are known to cause localised seismic excitation above background noise levels. In this paper we investigate whether a comparable far-field 'quietening' could be observed during Superbowl LX (February 8, 2026) in the city of Seattle, hometown of the Seattle Seahawks, as people stayed indoors to watch the game. We find that a [...]
HyGage: Solving the Hysteresis Puzzle with a New Streamflow Monitoring Method
Published: 2026-02-12
Subjects: Engineering, Physical Sciences and Mathematics
The questionable reliability of discharges obtained using the traditional stage–discharge method under gradually varied flow conditions continues to motivate the search for improved monitoring approaches that support water resources management, streamflow forecasting, and multipurpose scientific investigations related to the water cycle. This paper introduces HyGage, a new physically based [...]
A suspended adsorbent filter for arsenic removal from water to address UN 2030 agenda for sustainable development
Published: 2026-02-12
Subjects: Engineering
Magnetite particles are widely recognized as green and sustainable material for advanced water treatment. The magnetite particles are synthesized through a simple electrochemical process at room temperature from an iron-based electrode immersed in an alkaline aqueous medium at pH 10.5. Arsenic adsorption kinetics were rapid, and adsorption reaction can reach equilibrium within 10 minutes [...]
MACROM: An Optimal Control Model for Balancing Climate Change Abatement and Damage Trade-offs
Published: 2026-02-11
Subjects: Applied Mathematics, Climate, Environmental Indicators and Impact Assessment
The current pace of global emissions reduction is inadequate to meet the Paris Agreement temperature target of 1.5°C. While carbon dioxide removal (CDR) is increasingly viewed as necessary to meet these targets, questions remain about the optimal scale and timing of deployment when both costs and climate damages are considered. Here we present MACROM, an optimal control climate-economic model [...]

Compound Drivers of Antarctic Sea Ice Loss
Published: 2026-02-10
Subjects: Oceanography
Antarctic sea-ice extent began declining since 2015, reaching its lowest extent in the post-1970s observational era in 2023. To diagnose the drivers of this decline, we analyse an observationally constrained sea ice-ocean model spanning 2013-2023, and identify three distinct phases of sea-ice retreat. First, an intensification of westerly winds preconditioned the Southern Ocean via increased [...]
LLM-augmented taxonomy for >4500 palaeopalynology genera
Published: 2026-02-07
Subjects: Earth Sciences, Environmental Sciences, Mathematics
Large Language Models (LLMs), being text-based, are ideal types of artificial intelligence to consider the complexities of palaeontological taxonomy because palaeontology depends on published textual descriptions as the primary, authoritative record of a taxon. This paper describes (1) the preparation of palynological (the study of organic-walled microfossils) taxonomic text contained within the [...]
A Domain-Based Evolution Model for Red Sea: New Sea-Floor Spreading Evidence
Published: 2026-02-07
Subjects: Earth Sciences
The propagation of the Red Sea continental margin remains unevaluated. Despite the unanimous agreement that the southern Red Sea axial ridge valley is underlain by juvenile oceanic crust, there is a lack of such agreement for the central and northern Red Sea. Significant issues relating to Red Sea tectonics are whether the Arabian and Nubian plates have been completely separated (i.e., oceanic [...]
