Coupling sPCA‐Based Statistical Modeling With Deep Residual Networks Considering Thermal Effect for Deformation Forecasting in High Dams

Structural Control and Health Monitoring, Volume 2025, Issue 1, 2025.
Accurate prediction of deformation under thermal influences is critical for the safety assessment and long‐term performance of high dams. This study proposes a novel two‐stage prediction framework that integrates statistical modeling with deep learning to enhance the interpretability and accuracy of dam deformation forecasting.

Altered flow and sediment transport impacts on the ecosystems of Chinese major rivers: An urgent call for eco‐fluvial dynamics

River, Volume 3, Issue 4, Page 341-361, November 2024.
Abstract River ecosystems face challenges due to environmental degradation and alterations in flow and sediment transport resulting from climate change and other anthropogenic impacts. These changes may substantially affect river morphology, nutrient dynamics, wetland vegetation, aquatic habitats, and river ecological stability.
