Influence of fluvial engineering works and topo-sedimentary response at different hydrological events, the middle Loire River

Abstract : The Loire River dynamics is influenced by two main factors: hydro-climate change and anthropogenic pressures. These have caused incision of the river bed and narrowing of the active channel. The fundamental question on the local geomorphological response of the riverbed to the disturbances is addressed through the study of three sites in the middle part of the Loire. Study sites are subjected to different degrees by human activities. The objective of this paper is to determine the interactions between sediment dynamic with annual and five-year flood and the impact of human activities. The results highlight the influence of fluvial engineering works (bridges, old docks, weirs and dikes) on the morpho-sedimentary evolution of the river bed. The flood occurred in November 2008 had a different geomorphic impact in the three study sites. This flood resulted in a temporary accumulation of sediment at sites influenced by human activities. Post flood erosion occurred in the three sites, but at different rates.
