CHANNELIZATION AND CONSEQUENCES ON FLOODPLAIN SYSTEM FUNCTIONING ON THE GARONNE RIVER, SW FRANCE

摘要

This study focuses on changes in flow dynamics and morphology of the river bed in altering floodplain system functioning. Evan though direct training works on the Garonne River channel on the upstream reach are moderate, human effects on the river channel have irreversible effects. A few aspects of the complex relationship between the contemporary hydrological and geomorphological river channel changes and the adjacent floodplain system are examined to provide further understanding of the whole fluvial hydrosystem, its haitats and its ecological functioning.
