How long can you expect that to last?" said Jim Walker, director of navigation policy and legislation for the American Association of Port Authorities, who formerly ran the U.S. ![]() "You're using this infrastructure that was essentially built by our grandparents. But more than half of the country's locks and dams are at least 50 years old, and funding has not kept up with demand for maintenance. Traffic through the Brazos gates has surged by 40 percent over the last three years, channeling more than 2.5 million tons of cargo a month to support a strengthening U.S. ![]() The wooden sides of the channel are pocked from scrapes and bumps. The Brazos floodgates and their bank walls take more hits from boats and barges than any other of the 242 locks and dams among American rivers - about one every four days, staff estimated. "It's like a small freight train on ice," assistant lockmaster Robert George said. The 60-degree angle boats must turn while navigating the river between the gates is one of the toughest stretches to maneuver. Towing barge carrying 3,500 tons of liquid asphalt slides through the 75-foot-wide east gate toward Galveston, churning more silt behind it.

The author of this article was a member of the Working Group and would like to share some conclusions of the report with the readers of our magazine.1 of4 A 54-foot wide chemical barge carrying 3,500 tons of liquid asphalt passes through the 75-foot wide Brazos River floodgate east gate, Tuesday, March 24, 2015, in Freeport. The final report was presented on a workshop in Brussels on November 6, 2017. This Working Group, abbreviated as WG-154 of the PIANC Inland Navigation Commission (InCom), has recently completed its proceedings. It should, therefore, not surprise that PIANC, the World Association for Waterborne Transport Infrastructure, established a Working Group to bring a report on the newest state-of-art technology in this field. ![]() Miter gates are by far the best known and usually the most efficient type of such closures. This stimulates the development of lock closures, which are often seen as the most technically demanding systems in navigation locks. Growing significance and requirements of recreational navigation.Impact of processes associated with climate change, like sea level rising and extreme weather conditions on inland waterways.Environmental advantages of inland navigation versus land transport.The resulting growth of both number and sizes of vessels in navigation locks.Globalization of world economy and more demand for waterborne transport.The reasons for this renewed interest are complex and can be associated with a number of world-wide developments and concerns, like: This also includes the upgrading and refurbishment projects at many existing lock sites. Construction of navigation locks enjoys renewed interest of inland waterways and sea harbors administrations. ![]()
