Floods in Northern Australia
| Title |
Floods in Northern Australia |
| Description |
Floods swept across Australia's Northern Territory as the six-month rainy season drew to a close in April 2006. Worst-affected was the city of Katherine, where water from an overflowing Katherine River reached up to the roofs of houses in some areas, reported the Australian Broadcast Corporation (ABC). The floods around Katherine had largely subsided when the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Terra [ http://terra.nasa.gov/ ] satellite acquired the top image on April 10, 2006, but the nearby Daly River was still swollen. Though not visible in this image, the city of Katherine sits along the Katherine River near the point where the label meets the river. The only clear signs of human habitation are brilliant green squares created by agriculture along both rivers. In addition to farm fields, large pools of flood water, inky black in this image, also line the banks of the Daly River. According to ABC News, the river was still rising on April 10, and those who lived in the town of Daly River near the river's mouth, were preparing to evacuate. The lower image, from March 1, 2006, shows the river basin earlier in the rainy season before the floods set in. To track the floods, see the MODIS Rapid Response Web site, where daily images [ http://rapidfire.sci.gsfc.nasa.gov/subsets/?Australia2/2006098 ] of Australia are available.

Floods in Western Australia
| Title |
Floods in Western Australia |
| Description |
As cyclones go, Cyclone Emma [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php 3?img_id=13385 ] was weak, forming just before coming ashore with winds gusting to less than 90 kilometers per hour (56 miles per hour). The storm did, however, drape itself over the whole of Western Australia on March 1, 2006, bringing a deluge of rain. In the midst of its wet season, the region was already soggy when Emma came ashore, and the storm's heavy rains triggered widespread flooding. Water spilled out of river basins and filled seasonal lakes across the state on March 2, when the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Aqua [ http://aqua.nasa.gov/ ] satellite took the top image. In this image, the rivers and streams in the Murchison and Gascoyne River Basins have expanded into satiny ribbons of dark blue, with pale blue streaks formed by muddy channels. These rivers are in central Western Australia, east of Shark Bay and well inland from where the storm first struck, but similar floods are apparent throughout the state in the large image. In the ten days that passed between when the top and the bottom images were taken, plants have clearly flourished with the late summer rains. The brushes of green on the arid tan and pink landscape expanded, particularly around the rivers, which almost appear to be glowing in a halo of green by March 2. Popcorn clouds drifting over the flood region are pale blue in this false-color satellite image.

| Description |
Although eight days had passed since Cyclone Emma drenched northwestern Australia, flooding was more dramatic than it had been immediately after the storm came ashore on March 1, 2006. By March 8, top image, upstream floodwater had swollen the web of rivers in the center of the image and spread across the dry landscape. Additional flooding is apparent near the shore along the top of the image, and the cloud of bright blue offshore indicates that mud-laden water is draining into the Indian Ocean. The Australian Broadcasting Corporation reported that the floods had stranded or killed cattle in the rural region.Daily images [ http://rapidfire.sci.gsfc.nasa.gov/subsets/?Australia1/ ] of northwestern Australia are available from the MODIS Rapid Response Team.
