"..Some of the findings were expected, others are surprises. McCourquodale’s group has been looking at the flow of water and sediment in the lower river, and what happens to those flows when a diversion is opened.
“We modeled one large diversion (250,000 cubic feet per second) on the upper section (of the lower river) and we found it dramatically reduced the amount of water and sediment available on the lower river,” he said.That finding had greater implications when tied to another of the team’s discoveries: 50 percent of the river flow that passes Belle Chasse left the system before the river reached Head of Passes south of Venice. Most of that was exiting a series of natural openings on the east bank."
