Sens techniqueOperation to lower water level and increase outflow rates to discharge some of the sediment retained by a dam. A dam release consists in opening the gates, thus limiting the silting of the dam reservoir and the risk of flooding. This operation, although common in the management of harnessed rivers, can have adverse effects on the downstream environment (decrease of oxygen levels in water, obstruction of fish gills by suspended solids, etc.).
