| In the context of the METROC project, academic modelling of dissolved and particulate materials were done with the MARS3D model. Considering the dissolved materials, we calculated evacuation times and residence times. Then, we add minimal dilution and percentile maps to assimilate the modelling and the realistic dissolved metal discharge. Considering the particulate materials, we did balance sheets for material exported, sedimenting or staying in water for three different phases (whole modelling 13 October – 31 December 2008, flood situation and resuspension situation). Maps of Marseille roadstead complete that information and allow visualising the principal deposition area. We will continue this work by modelling reel material such as Lead. |

| Human pressures on ecosystems have increased significantly over the last decades, and especially Mediterranean coasts are strongly impacted by the development of big cities and industrialized area, such as the Bay of Marseille. Prior to any investigations on ecological or contamination impacts, it was necessary to understand sediment dynamics and its response to natural extreme events such as storm or heavy rainfall events. In situ observations were dedicated to understand the behavior of bed sediments, and their spatial distribution. A benthic station was deployed for three months to observe the impact of extreme events on hydrodynamics and sediment dynamics in a critical zone of the study area. These measurementswere used to calibrate and validate the... |
