Article paru en 2024 dans : Journal of geophysical research : oceans

Introduction
Model approach and observations
– Model description
– The Loire: geometry and water motion
– Historical and present observations of sediment concentrations
– Calibration and experiment set?up
Results
– Default case-summer in year 2000
– Summer in year 1900
– Effect of deepening between 1900 and 2000
– Analysis of mechanisms
Sensitivity analysis
– Effect of discharge in 2000
– Combined effect of various uncertain parameters and deepening
Discussion
-Interpretation of the regime shift and limitations
– Comparing to the ems and implications for other estuaries
Conclusions
