Rising Water along the Ganga River
This page contains archived content and is no longer being updated. At the time of publication, it represented the best available science. However, more recent observations and studies may have rendered some content obsolete.
Flooding in more than 1,000 villages in Bihar forced residents from their homes by late August 2011, the Indo-Asian News Service reported. After two years of drought, the Kosi River and Ganga (Ganges) Rivers were rising rapidly.
The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite captured these images of a stretch of the Ganga, or Ganges, River around Patna August 30, 2011 (top), and June 23, 2011 (bottom). These images use a combination of infrared and visible light to increase contrast between water and land. Water ranges in color from electric blue to navy. Vegetation is green. Clouds are pale blue-green.
Water often rises along the Ganga during monsoon season, which typically lasts from June to August. In August 2011, however, waters rose high enough to pass the danger mark in multiple locations. In the image from August, the swollen river has spilled onto floodplains to the north and south. The Indo-Asian News Service reported widespread damage to crops as well as destroyed homes.
