Ural River delta: NASA photographs (A) October 1994 (STS068-202-069); (B) May 1996 (NM21-740-055). The Caspian has also encroached upon the delta of the Ural River, the headwaters of which are in the southern Ural Mountains. Although it can be difficult to distinguish water from vegetation, there are differences (arrows). The most notable differences are in the southernmost lobe-for example, the widths of channels separating subaerial islands. In view (B) sunglint lends emphasis to submerged areas and one can see that exposed dredge spoil east of the main channel has decreased markedly (C). Along the shorter, western canal the banks that were exposed in 1994 were almost entirely submerged or eroded two years later (at A). Sunglint also highlights what appears to be a network of levees-possibly roads or canals-that have been flooded east of the river channel (at B).
