Continuous Management of the Channel Design to Optimize Navigability in the Middle Paraná River Waterway: “Santa Fe – Confluence”. Argentina

Abstract This paper exposes how HIDROVIA S.A. (Inland Waterway Concession company) worked in the Middle Paraná River inland waterway “Santa Fe – Confluence” to maintain navigation channel without dredging works by means of four steps: frequent bathymetric surveys, study AIS vessels tracks, a special coordination logistic river with technical team and buoy tenders crew effective communication plans involved stakeholders. is stretch well-known Paraguay Inland South America that reaches deep waters Río de la Plata. Physical characteristics depths along this section determine what kind can sail according its draught up 10 ft. With 2 For under keel clearance. From October 2010 September 2021, installation maintenance modern aids system were granted concession company. Given intense morphological dynamics thalweg migration section, contract stated it was no suitable keep fixed design permanent works. It established should only be done when where not possible readjustment profile partial changes trace direction axis. The Aids Navigation Department S:A. succeeded doing implementing continuous management optimize sustainable Santa Confluence waterway.
