Experimental Study on Fine Sediment Infiltration (FSI) Processes in Different Gravel Mixtures
River Research and Applications, EarlyView.ABSTRACT Fine sediment infiltration (FSI) can lead to riverbed clogging, thereby degrading important habitats for aquatic biota in the hyporheic interstitial zone of gravel‐bed rivers (e.g., by reducing oxygen availability). This stress on rivers may increase from anthropogenic influences and can be counteracted by artificial gravel augmentation to ...

Influence of Three Gorges Dam on earthquakes based on GRACE gravity field
Open Geosciences, 2022 After the completion of the Three Gorges Dam, it increases the risk of inducing an earthquake. We use the GRACE Gravity Field Model to analyze the relationship between the operation of the Three Gorges Reservoir and the change of gravity field in western

River, EarlyView.The study revealed that while groundwater depth trends were generally risk‐free, electrical conductivity showed localized risks in 38% of the Aksu Irrigation System. Overall, 25% of the area was classified as risky. The integrated GIS‐based approach provides a rapid, objective, and cost‐effective tool for precision water management. Abstract Continuous

National Policy Coherence Counts for Reducing Inequality in Global Climate and Development Agendas
Sustainable Development, EarlyView.ABSTRACT International institutions promote policy coherence as crucial to the effective and fair implementation of global sustainability agendas, though the evidence for its benefits is slim. We present here the first systematic cross‐country dataset on the consequences of national government efforts to promote policy coherence for vulnerable groups ...

Seismic Fragility Analysis of Gravity Dams Considering the Fuzziness of Damage States Thresholds
工程科学与技术, 2020 Since the evolution of the structural damage states is a gradual transitional process and the fuzziness of cognition, the thresholds of damage states of the gravity dams are fuzzy, which will affect the evaluation results of damage states of gravity dams.

Sustainable Development, EarlyView.ABSTRACT This paper examines the environmental implications of tariffs on greenhouse gas emissions embodied in extra‐European Union imports consumed by domestic final demand in the EU. Using a multidimensional country‐sector‐year framework, the study investigates whether tariff changes are associated with variations in trade‐embodied emissions and ...
