Abstract

The Multidisciplinary Study Team “Plan Loire Grandeur Nature” has initiated projects aiming at improving the understanding of the behaviour of the Loire River and its tributaries. A measurement strategy will be developed, and data will be used to improve the understanding of the morphological behaviour of the Loire River and of its sediment movement, especially on bedload. Five test sites were selected, where surveys start in 2002. Some hydrographic surveys were already performed in one of the sites during a flood in April 2001, near the city of Nantes. Sediment measurements are planned during spring and autumn of 2002. Surveys will help understanding the way the riverbed morphology adapts during the flood. Bedload data will be used in a mobile-bed scale model to simulate morphological changes at all flood stages. A two- (or may be three)-dimension numerical river model will be tested later on, with as input the results of the field and scale model studies. One purpose of the project is to find out how to build efficient and sustainable riverbank protections. The field and model studies will allow to compare various alternative techniques for riverbank protection. The project will be completed in 2005, so that results could be utilised for setting up the next Loire River management contract between the French State and the regional authorities, starting in 2006.
