Floods in Southern Africa

Floods in Southern Africa |
| Description |
A black web of water surrounds the Zambezi River in the top image, captured by the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Terra [ http://terra.nasa.gov/ ] satellite on February 10, 2007. Mozambique was experiencing its worst floods in six years when the Zambezi flowed over its banks in January and February 2007, reported the United Nations Office for the Coordination of Humanitarian Affairs (OCHA [ http://www.reliefweb.int/rw/RWB.NSF/db900SID/YZHG-6YCQR4?OpenDocument&rc=1&emid=FL-2007-000011-ZMB ]). As of February 12, an estimated 29 people had died and 60,000 had been evacuated from the river's banks. Early and heavy rains fell over the entire Zambezi Basin, pushing the Zambezi and many of its tributaries into flood stage. The floods are likely to worsen as the 2,574-kilometer-long river receives water from its swollen tributaries in Angola, Namibia, Zambia, and Malawi. Releases from the massive Cahora Bassa Reservoir, [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=14110 ] which is reaching its capacity, are also expected to make flooding worse along the lower Zambezi. These images show the lower Zambezi where it meets the Shire River flowing south from Malawi, one of the most severely affected regions in Mozambique. The top image provides a remarkably cloud-free view of the floods, while the lower image, taken on December 31, 2006, shows the region before the rains started in January. The images were made with a combination of infrared and visible light to highlight the presence of water on the ground. Water is black or dark blue, while plant-covered land is green. Bare earth is tan and pink, and clouds are pale blue and white. Fires are outlined in red. Images such as these and photo-like, true-color images are provided by the MODIS Rapid Response Team [ http://rapidfire.sci.gsfc.nasa.gov/subsets/?FAS_SMozambique/2007041 ] on a daily basis.

Oshigambo River and Etosha P
…
| Title |
Oshigambo River and Etosha Pan, Namibia |
| Description |
Etosha Pan in northern Namibia is a large, dry lakebed in the Kalahari Desert. The 120-kilometer-long (75-mile-long) lake and its surroundings are protected as one of Namibia's largest wildlife parks. Herds of elephants occupy the dense mopane woodland on the south side of the lake. Mopane trees are common throughout south-central Africa, and host the mopane worm, [ http://www.mopane.org/biology.htm ] which is the larval form of the Mopane Emperor Moth and an important source of protein for rural communities. About 16,000 years ago, when ice sheets were melting across Northern Hemisphere land masses, a wet climate phase in southern Africa filled Etosha Lake. Today, Etosha Pan is seldom seen with even a thin sheet of water covering the salt pan. Two images taken about nine months apart document an unusually wet summer in southern Africa. The upper view (March 2006) shows the point where the Oshigambo River flows into the salt lake, the lower regional image (June 2005) shows the same inlet—but dry—on the north shore of Etosha Pan. The Oshigambo River is almost never seen with water, but in early 2006, rainfall twice the average amount in the river's catchment generated flow. Greens and browns show vegetation and algae growing in different depths of water where the river enters the dry lake (upper image, center). Typically, little river water or sediment reaches the dry lake because water seeps into the riverbed along its 250-kilometer (55-mile) course, reducing discharge along the way. In this image, there was enough surface flow to reach the Etosha Pan, but too little water reached the mouth of the river to flow beyond the inlet bay. The unusual levels of precipitation also filled several small, usually dry lakes to the north (upper image, right). Astronaut photograph ISS012-E-23057 [ http://eol.jsc.nasa.gov/scripts/sseop/photo.pl?mission=ISS012&roll=E&frame=23057 ] was acquired March 2, 2006, with a Kodak 760C digital camera using a 180 mm lens. The regional oblique view, ISS011-E-9504, [ http://eol.jsc.nasa.gov/scripts/sseop/photo.pl?mission=ISS011&roll=E&frame=9504 ] was taken June 24, 2005, also with the Kodak 760C and a 180 mm lens. Both images are provided by the ISS Crew Earth Observations experiment and the Image Science & Analysis Laboratory, Johnson Space Center. The images in this article have been cropped and enhanced to improve contrast. The International Space Station Program [ http://spaceflight.nasa.gov/home/index.html ] supports the laboratory to help astronauts take pictures of Earth that will be of the greatest value to scientists and the public, and to make those images freely available on the Internet. Additional images taken by astronauts and cosmonauts can be viewed at the NASA/JSC Gateway to Astronaut Photography of Earth. [ http://eol.jsc.nasa.gov/ ] |

Flooding in Namibia
| Title |
Flooding in Namibia |
| Description |
Several days of heavy rain triggered devastating floods in south-central Namibia at the end of February 2006. The rains filled the Hardap Dam, and on Saturday, February 25, the water flowed through the flood gates and flooded the city of Mariental. When the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Terra [ http://terra.nasa.gov/ ] satellite captured the top image on February 27, the overflow of water had swollen the Fish River south of the city. The bright green agricultural region around the city was also still flooded when this image was taken. According to the United Nations Office for the Coordination of Humanitarian Affairs, 122 houses and 80 businesses were submerged at the time of this image. Two people drowned in the floods. These images are shown in false color. Plant-covered land is green, with agricultural land much brighter than natural vegetation. Bare earth is tan and pink, water is blue, and clouds are pale blue and white. The lower image shows the Hardap region on February 15 before the rains started. NASA images created by Jesse Allen, Earth Observatory, using data obtained from the Goddard Earth Sciences DAAC. |

Flooding on the Zambezi Rive

Flooding on the Zambezi River |
| Description |
Nearly every April, Africa's Zambezi River swells with seasonal rain, spreading across its broad flood plain in Angola and Namibia. Some of the people most seriously affected by the regular floods live in Namibia's Caprivi Strip. As of April 11, 2006, seven settlements in the flood-prone region were surrounded by water, reported the New Era, a Namibian newspaper. The region was clearly flooded in a false-color satellite image taken on April 11 (top), by the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Aqua [ http://aqua.nasa.gov/ ] satellite. In this image, water is black and dark blue, clouds are pale blue, plant-covered land is green, and bare earth is tan. In the three and a half weeks that passed between the time the top image was acquired and the time the lower image was acquired, the eastern tip of the Caprivi Strip turned into a vast shallow lake. Though the river was still rising, the floods were nowhere near the record-setting levels seen in 2004 [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=12081 ]. NASA image created by Jesse Allen, Earth Observatory, using data obtained courtesy of the MODIS Rapid Response [ http://rapidfire.sci.gsfc.nasa.gov/ ] team and the Goddard Earth Sciences DAAC.
