Prediction Model for Compaction Quality of Earth-Rock Dams Based on IFA-RF Model

Applied Sciences
The current evaluation models for earth-rock dam compaction quality seldom incorporate parameter uncertainty considerations. Additionally, the existing models frequently demonstrate constrained prediction accuracy and generalization capabilities.

Application of a Presumptive Standards Approach to Evaluate Environmental Flows in a Highly Regulated River Basin

River Research and Applications, EarlyView.
ABSTRACT The presumptive standards approach to environmental flows offers a method to develop interim guidelines for ecological and social‐cultural flow needs. The approach is based on deriving acceptable percent‐of‐flow limits based on naturalised flows (the absence of depletion or alteration of flow), and it can be an effective precursor to a full ...

The Role of Sediment Supply on Fish Habitat Dynamics of a Morphologically Active River Widening

River Research and Applications, EarlyView.
ABSTRACT Restoration measures, such as river widening, aim to reactivate key morphodynamic processes, which are critical drivers of fluvial habitat dynamics. While some evidence supports the important role of sediment supply on river widening's morphology, its link to fish habitat availability and dynamics remains unclear.

Retrospective image analysis for long‐term demography using Google Earth imagery

Remote Sensing in Ecology and Conservation, EarlyView.
We demonstrate that high‐resolution Google Earth imagery, combined with minimal field validation, enables retrospective tracking of individual invasive plants. The image shows one of the monitored individuals of Opuntia sp. in Greece. Our approach reveals long‐term demographic patterns, recruitment dynamics, and spatial expansion without continuous ...

Isolation, Insularity and Resilience: A Review of the Geophysical, Socioeconomic, and Environmental Vulnerabilities of Gran Canaria and Lesvos Islands for Policy Interventions to Global Change

Sustainable Development, EarlyView.
ABSTRACT The dynamic nature of small islands being geographically isolated and their perceived connectedness with global networks complicates research attempts to draw general conclusions on whether insularity leads to marginalization or strengthens their resilience for sustainable development.

Concrete in architecture: Redefining form, space, function, and insights from bibliometric analysis

Structural Concrete, EarlyView.
Abstract Concrete has become a cornerstone in architectural and engineering innovation, as it seamlessly integrates structural performance with artistic expression. Its evolution from ancient opus caementicium to contemporary ultra‐high‐performance concrete illustrates its adaptability to the change in technological, environmental, and design paradigms.

Ecotoxicological Assessment of Mercury in Fish From a Gold‐Mining‐Impacted Amazonian River: Biomonitoring and Human Health Risk

Environmental Toxicology, EarlyView.
ABSTRACT The Peixoto de Azevedo River, located in northern Mato Grosso, southern Brazilian Amazon, has a long history of artisanal and small‐scale gold mining (ASGM). This study evaluated total mercury (THg) concentrations in fish tissues to assess biomagnification and potential risks.

Detection method and index probability statistical analysis of sand and gravel dam material gradation based on image recognition

Journal of Intelligent Construction
The traditional evaluation concept for the design of earth-rock dams relies on a limited number of test pit results, leading to issues such as insufficient data and poor representativeness.
