| Abstract |
The estuarine turbidity maximum (ETM) is one of the main drivers of longshore and cross-shore sediment transfers in macrotidal estuaries. Besides the quantification of the ETM sediment mass and its spatial expansion, the challenge is to understand its dynamics associated with the long term (~50 years) estuary morphodynamics. This study is based on a realistic 3D hydro-sediment dynamics modelling of the Seine estuary (France) in order to quantify the influence of hydro-meteorological forcing on ETM characteristics. The diachronic analysis of years 1960, 1975 and 2010 provides understanding on the influence of the different bathymetries on the ETM dynamics. The ETM seaward migration from 1960 to 1975 and its upstream migration from1975 to 2010 is related to extensive engineering works through the 20th century that lead to significant tidal asymmetry changes. |
