Abstract

The CRUE-SIM project (2014-2017) is an interdisciplinary project that brings together atmosphere physicists, hydrologists and oceanographers to study and model flash floods across the Mediterranean region : it integrates water and sediment transport as a consequence of intense rainfall, from the catchment to the sea. The objectives of the project are (1) the coupling between atmosphere, ocean and sea with continental hydrological and hydrodynamic models and (2) the integration of the feedbacks and the forcing continuity from one compartment to the other along the brief but intense events that will be studied. Considering the 1400 km² Têt Mediterranean river basin (southwestern France) as a case-study, two hydrological models will be used at different time and spatial scales: the low resolution SWAT model outputs will be used as the inputs of the high resolution MARINE model, both using rainfall forcing from the Meso-NH atmospheric model. The feedback of the storm surge on the downstream part of the basin will be considered thanks to the SYMPHONIE ocean model. We will quantify the fluxes, at a sub-daily time-step, of water and of suspended particulate matter transported during floods from the soil to the river and from the river to the sea. The CRUE-SIM project is one of the research lines of the SEDILION project funded by RTRA-STAE focused on the transport of dissolved and sorbed matter during flash floods.
