Abstract: Researches on individual river meander length have been vastly carried out. While research on the changing of meandering rivers length based on the historical maps from satellite images have not yet been undertaken. This research intends to answer the question whether the length of a segment of meandering river and river sinuosity will differ or stay relatively the same given its morphological development. This research analyses 30 satellite images of meandering rivers from the diverse of locations (USA, New Mexico, England, Romania and New Zealand). With the remote sensing techniques and image interpretations the length of each meandering river segment and river sinuosity can be analyzed and measured. The results are then proven through the physical-mathematical analysis based upon the theory of potential and kinetic energy as well as the continuity of discharge. The result explains that the length and sinuosity of meandering rivers in its morphological development is relatively the same. It rejected the general understanding that the length of meandering river is shortened by cutoff evens. In fact, the energy of the cutoff is transformed to downstream, intensives the bank erosion and increases the meander length to equilibrium.
