This department uses, in particular, a dozen measurement points situated in Paris and upstream of the capital. The data collected makes it possible to manage, in particular, road closures along riverbanks, access to the cities and all other measures needed to protect public roads and the sanitation network in the event of flooding (closing stormwater drains and preventing river transport, etc.).<\/p>\n<\/div><\/div><\/div>\n<div class=\"block\"><div class=\"title\">DESCRIPTION OF THE APPLICATION<\/div><div class=\"text\"><div class=\"text-container\"><p>\nOne of the level measurement points for the Seine is situated under the Pont d\u2019Austerlitz in the heart of Paris.
