ANIMATION: Evolution of a Meandering Stream
People building communities along a riverbank mistakenly assume that the shape of a meandering stream will remain fixed for a long time. In fact, in a natural meandering river system, the river channel migrates back and forth across the floodplain. View 1 illustrates the processes of erosion and deposition, and View 2 shows the evolution, in map view, of a meandering stream. For more information, see Section 17.6 Streams and Their Deposits in the Landscape starting on p.593 and Figure 17.22 on p. 598 in your textbook.
Zoomable Art: River Systems
Rivers, or streams, drain the landscape of surface runoff. For more information, see the Featured Painting on pp. 608-609 in your textbook.
