Long term evolution of a dam reservoir subjected to regular flushing events
An analysis of the long term morphological evolution of the Génissiat reservoir (France) is provided. First, a methodology for bathymetric data processing and reservoir sediment volume budget calculation is described. An estimation of global uncertainties in volume calculation is proposed.

| Summary: | An analysis of the long term morphological evolution of the Génissiat
reservoir (France) is provided. First, a methodology for bathymetric data
processing and reservoir sediment volume budget calculation is described. An
estimation of global uncertainties in volume calculation is proposed. The
reservoir bathymetric budget for several dam flushing events and interflush
periods is presented, showing the global decrease of deposited sediment
volume with time. The spatial dynamics of the reservoir subreaches is
highlighted and typical patterns in flush and interflush periods are
identified. |
