Memphis, Tennessee (AP) - nearly 100 ships, barges, waiting for the Monday through 11 miles of the Mississippi River due to the low water level has been closed, the coast guard said.
New Orleans coast guard spokesman Ryan Tippets said, Mississippi near greenville reach has intermittent closed, since August 11th, when the beaching.
Such as track said, this area are investigating, dredging and coast guard boat are replacing eight navigation mark. He said, 40 professional ship and 57 southbound ship stranded, waiting for the Monday afternoon.
Such as track said, it is not awake immediately river will be re-opened. A near greenville reach also be closed in 1988, because of the serious drought caused by low water level. The river Memphis meter, set a record low.
From Illinois to Louisiana, Mississippi River have seen, water level dip because in the past 3 months under drought condition. Near Memphis, the river water level more than 12 feet below normal for this time of year.
Maintenance channel is indispensable, to keep the ship collision or on the rocks. Thousands of tons of supplies to the river every day.
American army engineers are using excavator mining sand production, ensure channel depth barge loading coal, steel, agricultural products and other commodities. Bianconeri is necessary, to provide minimum 9 feet deep, 300 feet wide of the Mississippi River downstream channel.
Pay the cargo handling materials and downstream, every day in the complain, shallow river, in order to reduce their barge on the load, in order to avoid sole. Light load for the owner, still have to handle the cost, such as labor and fuel means income decrease.
In addition, low water wharf and terminal becomes more difficult to load or unload materials, such as ships have close enough to the terminal of the trouble.
Memphis's north of the city centre last Friday, dredge hurley cut JiangDe to ensure that ships safe passage is a 2000 - foot - long large. Opening up is called the dustpan, which means that it USES vacuum suction to suction sand JiangDe, said the captain, frank Segree.
Hurley can dredge 75 feet in depth can remove as much as each hour 5000 cubic yards of sediment. This is in one hour, enough to fill about 68 backyard swimming pool.
Sand is deleted, it, and then through a 1200 - foot - long duct deposited bank push. To be on the safe side, dredge tried to make channel depth more than 9 feet mark the Segree said as much as possible.
350 - foot - long dredge is by the three combination produces 10000 horsepower and cylinder engine provides the power to, but the ship mobile only 0.12 miles per hour, because it slowly to litter cleaning from channel.
Before the start of dredging projects, surveyors check to see that more shallow, ford is located in JiangDe. Dig in a position, investigators and dredge move to another trouble point.
"We played high, then let the way," Segree said, added that this has been his most busy year, dredging, 20 years, he has been with the bianconeri.
The river is in Memphis minus 8.5 feet (Friday) according to the engineer's legion. "Reduce" reading does not mean that the river is dried up - it is just a measurement on the basis of the design of the Memphis river meter. Essentially, sensing device river level was far below the normal level.
The Mississippi River near Memphis the lowest measured water level record is minus 10.7 feet, in 1988. The team has said, the river is not expected to a record low.
Segree said, 4 dredger is currently from st. Louis to fort vickers, Mississippi, perform the work, it is necessary to the United States by public industry, but almost no one noticed.
