Tobol River, Russia October 1994. Described by many scientists as the world’s largest unbroken lowland, the West Siberian Plain is a region of numerous river basins and broad expanses of swampy terrain. The Tobol River flows northeasterly until it merges with the easterly draining Tavda River and then the Tobol takes an easterly course. Notice that both rivers have very dramatic meandering stream channels. In particular the Tobol River has an assortment of meander scars and several oxbow lakes that have formed in the wide floodplain of this constantly changing river. East of the confluence of these two rivers (lower left quadrant) the Tobol River becomes a winding stream. The nature of the color infrared image with the pinkish-looking areas (representing green vegetation) scattered throughout the scene shows areas where vegetative cover can be mapped
