Syr Darya river meanders

Beautiful pictures from NASA EOS showing paleo and historic river meanders in the floodplain of the Syr Darya River in Kazakstan.

The floodplain is shown here as a tangle of twisting meanders and loops (image center). The darkest areas are brushy vegetation along the present course (filled with blue-green water); wisps of vegetation are also visible along flanking swampy depressions, or sloughs. An older floodplain appears as more diffuse dark vegetation (image upper left), where relict bends are overlain by a rectangular pattern of cotton fields. The straight channel of a new diversion canal—one of 16 from this point downstream—can be seen along the east bank of the river. The older floodplain is fed from the Chardara Reservoir, immediately upstream (not shown).
