Alex Neal from the Huntington District’s Engineering and Construction Division conducted a reconnaissance investigation of the Madeira River Navigation Channel as part of the USACE River Engineering Committee. The team shared knowledge with the Brazil Department of Transportation Infrastructure regarding methods to improve navigation reliability and minimize channel maintenance. Future collaboration on Brazilian engineering needs and projects are anticipated with the Brazil Department of Transportation Infrastructure which desires a long term relationship with USACE. This could provide assistance with their river navigation and engineering needs and potentially future planning of environmental ecosystem restoration projects of similar complexity in the future. This USACE contributions strengthen US-Brazil relationships in concert with U.S. Chief of Mission and U.S. Southern Command objectives for Economics, Environment Science & Technology, Health (ES&TH).
