text: # Association départementale Isère Drac Romanche
  
  The Isère-Drac-Romanche Departmental Association (French: Association départementale Isère Drac Romanche) is a public administrative establishment in France formed by the Conseil d'État in 1936. Its purpose is to maintain the system of flood-risk protection in the plains of the Isère, Drac, and Romanche rivers by preserving the integrity of embankments and their associated works. The organization performs all research and labor necessary for their preservation and keeps the system under constant surveillance in order to guarantee its efficiency in protecting the land and property at stake behind the embankments.
  
  ## Reinforcement work
  
  The Isère-Drac-Romanche Departmental Association performs important reinforcement work, employing techniques proper to civil engineering (embankment, pressure grouting, rockfill, gabion, sub-fluvial consolidation) and biological engineering (reinforced embankment, habitat restoration). As part of the Isère Amont and Romanche development projects, this mission now falls to SYMBHI, the Mixed Syndicate of the Hydraulic Basins of the Isère River (Syndicat Mixte des Bassins Hydrauliques de l'Isère). As new works are gradually built, the Isère-Drac-Romanche Departmental Association will assume their management. In other locations, like the regions of the downstream Isère, the Drac, and the Eau d'Olle, the association continues to perform research and work as needed.
