![]() ![]() No general theory of meanders is as yet satisfactory, however in fact, present evidence suggests that no single theory will explain the formation and characteristics of all meanders and that few of the physical principles involved have yet been clearly identified. Evidence on flow resistance in curved channels suggests that a basic aspect of meander mechanics may be related to the distribution of energy loss provided by a particular configuration or curvature. The origin and development of meandering river planforms has long been a focus of. Velocity distributions along river curves provide a generalized picture of flow characteristics. 1977: Morphometric definitions and classifications of oxbow lakes, Yukon River Basin, Alaska. SummaryEdit DescriptionRiver meander, outside of Kobuk Valley National Park (8029767197).jpg, (NPS Photo by Neal Herbert) Date, 24 July 2012, 19:05 Source. ![]() View the full answer Step 2/4 Step 3/4 Step 4/4 Final answer Transcribed image text: 5. Because such meanders carry no sediment, the shapes of curves in rivers are evidently determined primarily by the dynamics of flow rather than by relation to debris load. Step 1/4 Answer 6) part b - The processes that form a braided river differ from the meandering river are menti. Meanders formed by meltwater on the surface of glaciers, and by the main current of the Gulf Stream, have a relation of meander length to channel width similar to rivers. Most river curves have nearly the same value of the ratio of curvature radius to channel width, in the range of 2 to 3. ![]()
