Abstract
En 中文
Sediment transport analysis has evolved significantly with the simultaneous consideration of several ulometric parameters. However, in the case of complex areas subject to strong environmental and/or anthropogenic pressure, this approach may appear insufficient. In this context, MSTA integrates any of environmental information, in order to consider the local context. It thus improves the acuity of determination of sediment sources and transport fields identification (fine fraction, metallic element, Cherbourg roadstead has a complex environment which results to an heterogeneous and multimodal sediment cover. Anthropogenic activity is responsible for a significant disruption of the natural pattern of sediment distribution. The application of the MSTA approach in Cherbourg roadstead is based on the exploitation the results of an End-Members analysis (EM). Four sedimentary facies (EMs) are identified. EM1, consisting the finest sediments, has a dual marine and continental origin. EM2 (fine to medium sands) is transported tidal currents locally influenced by the morphology. EM3 (medium sands) constitutes a ubiquitous sediment at the scale of the North Cotentin with very weak dynamics. EM4 (coarse sands and gravels) is associated recent rock removal operations. The integration of EM data in the MSTA approach demonstrated its capacity to identify the sources and dynamics of the sediments constituting different recognized facies. Being able integrate any type of environmental parameters, MSTA offers the possibility of studying sediment dynamics in complex environments.
