U.S. Army Corps of Engineers to store water at Barkley Reservoir, reduce Ohio River and Mississippi River flood crests

U.S. Army Corps of Engineers, Nashville District

U.S. Army Corps of EngineersNashville, TN – The U.S. Army Corps of Engineers Nashville District announced today that it is continuing its flood control operation by using flood control storage in Lake Barkley to help mitigate the ongoing flood event on the Ohio River. This may cause minor high water impacts to communities along the Cumberland River in Lyon and Trigg Counties in Kentucky, and Stewart and Montgomery Counties in Tennessee.

Releases from Barkley Dam on the Cumberland River in Kuttawa, KY, are being reduced today as the Ohio River flood crest passes downstream. This reduction in discharge contributes to lowering the crest on the Ohio and Mississippi Rivers, thereby reducing flood risk at cities such as Paducah, KY, Cairo, IL, Memphis, TN, Vicksburg MS, and New Orleans, LA.

Cumberland River may rise due to U.S. Army Corps of Engineers flood Control operation at Lake Barkley.

NASA and NOAA Satellites observe Hurricane Nate make Landfall

 

Written by Rob Gutro
NASA’s Goddard Space Flight Center

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – NASA’s Aqua satellite and NASA-NOAA’s Suomi NPP satellite analyzed the temperatures in Hurricane Nate’s cloud tops and determined that the most powerful thunderstorms and heaviest rain areas were around the center of the tropical cyclone after it made landfall near the mouth of the Mississippi River.

At 8:00pm EDT/7:00pm CDT on October 7th, 2017 Hurricane Nate’s eye was at the mouth of the Mississippi River. National Weather Service radar data and surface observations indicated that Hurricane Nate made landfall near Biloxi, Mississippi, around 12:30am CDT/1:30am EDT on October 8th, with maximum winds of 85 mph (140 kph).

On October 8th at 4:20am EDT (0820 UTC) the MODIS instrument aboard NASA's Aqua satellite analyzed Nate's cloud top temperatures in infrared light and found strongest storms (yellow) around the center of circulation. (NASA/NRL)

NASA’s DopplerScatt Radar to Benefit Weather and Climate Studies, Maritime Uses

 

Written by Andrew Good
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Ocean currents and winds form an endless feedback loop: winds blow over the ocean’s surface, creating currents there. At the same time, the hot or cold water in these currents influences the wind’s speed.

This delicate dance is crucial to understanding Earth’s changing climate. Gathering data on this interaction can also help people track oil spills, plan shipping routes and understand ocean productivity in relation to fisheries.

Instruments already exist that measure ocean currents, and others that measure wind, such as NASA’s QuickScat and RapidScat. But a new, airborne radar instrument developed by NASA’s Jet Propulsion Laboratory in Pasadena, California, is able to measure both.

NASA uses Aircraft mounted instruments to examine growing Deltas in Louisiana

 

Written by Alan Buis
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – The Louisiana coastline is sinking under the Gulf of Mexico at the rate of about one football field of land every hour (about 18 square miles of land lost in a year). But within this sinking region, two river deltas are growing. The Atchafalaya River and its diversion channel, Wax Lake Outlet, are gaining about one football field of new land every 11 and 8 hours, respectively (1.5 and 2 square miles per year).

Last fall, a team from NASA’s Jet Propulsion Laboratory in Pasadena, California, showed that radar, lidar and spectral instruments mounted on aircraft can be used to study the growing deltas, collecting data that can help scientists better understand how coastal wetlands will respond to global sea level rise.

The History of Renfroe Station on the Red River, 1780 – Part 2

 

Clarksville Tennessee HistoryClarksville, TN – In 1780 a group of 300 daring pioneers decided to journey upon the Tennessee River and the Cumberland River in flatboats and canoes.

The destination for some of them would be present day Montgomery County, upon the Red River at the mouth of Passenger Creek. Yet, in order to arrive at their destination they had to guide their boats through a frontier full of Native Americans determined to attack them.

Why would they attempt such an endeavor which seemed to almost promise violence, deprivation, and other hardships?

NASA Survey discovers extensive coastal erosion from Gulf Oil Spill

 

Written by Alan Buis
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Dramatic, widespread shoreline loss is revealed in new NASA/U.S. Geological Survey annual maps of the Louisiana marshlands where the coastline was most heavily coated with oil during the 2010 BP Deepwater Horizon oil spill in the Gulf of Mexico.

Following the spill, the length of shoreline that receded more than 13 feet (4 meters) a year quadrupled compared to the year before the spill. The land losses occurred mainly in areas where oil had washed ashore during the spill.
