TL;DR: In this paper, the discharge/area relationship on the Nene and the Great Ouse has been analyzed and it was shown that the discharge required to make a stream misfit, as calculated from width/discharge and width/wavelength relationships established by hydrologisis, is such as to exclude the possibility that valley meanders can be eroded in present conditions.
Abstract: A MISFIT stream is a stream that is either too small or too large for its valley.' The fact that misfit streams are regionally distributed seems wholly opposed to the widely held view that they are usually due to capture. Field work provides consistent evidence that they have been affected by a reduction of discharge; for all those so far investigated are underlain by large alluvium-filled channels that meander round valley bends. The reduction of discharge required to make a stream misfit, as calculated from width/discharge and width/wavelength relationships established by hydrologisis, is such as to exclude the possibility that valley meanders can be eroded in present conditions. Analyses of the discharge/area relationship on the Nene and the Great Ouse, and field studies of meanders in very small catchments, provide particular evidence in support of the general conclusion. It is inferred that the large channels were filled with water, and the valley meanders eroded, by runoff supplied in climatic conditions different from those of the present day. Although distributional studies are handicapped by lack of detailed information, misfit streams are known to be widely distributed in certain parts of the world, and the wavelength/area ratio for valley meanders is found to be consistently of a single order. This fact is

TL;DR: In this paper, the authors considered the mechanics of meander development both in floodplain and incised streams and concluded that for streams of a given size, those that are incised have a larger maximum meander size than those flowing on floodplains.
Abstract: The Kickapoo region, located in the Driftless Area of southwestern Wisconsin, consists of a submaturely dissected plateau developed on gently dipping sedimentary rocks. The upland of the region has been variously interpreted as: (1) a series of single-cycle cuestas, (2) remnants of one peneplane on the lower parts of the upland, and (3) two peneplanes, one, that mentioned above, and another on the higher parts of the upland. From field observation and laboratory study of projected profiles the higher parts of the upland are interpreted as remnants of one peneplane—the Dodgeville of Trowbridge—thus eliminating the first two of the above interpretations. The lower parts of the upland, while possibly remnants of a partial peneplane, may equally well be interpreted as structural surfaces. These two conclusions constitute a fourth interpretation. The Kickapoo River is a strikingly misfit stream. In explaining the misfit relation, consideration is given the mechanics of meander development both in floodplain and incised streams. Both theoretical considerations and data from topographic maps indicate that for streams of a given size, those that are incised have a larger maximum meander size than those flowing on floodplains. Consequently, a misfit stream may result from the sudden change from incised to floodplain characteristics. This, as well as climatic change and underflow through the alluvium, is a possible explanation for the misfit character of the Kickapoo. The extensive alluvial deposits of the Kickapoo Valley, almost entirely the result of slope wash, probably result from aggradation of the Wisconsin Valley to which the Kickapoo is tributary.

TL;DR: A misfit stream is a stream that appears to be too small to have eroded the valley in which it flows; a stream whose volume is greatly reduced or whose meanders show a pronounced shrinkage in radius It is a common result of drainage changes effected by capture, by glaciers, or by climatic variations as mentioned in this paper.
Abstract: underfit stream (un-der-fit) A misfit stream that appears to be too small to have eroded the valley in which it flows; a stream whose volume is greatly reduced or whose meanders show a pronounced shrinkage in radius It is a common result of drainage changes effected by capture, by glaciers, or by climatic variations (Bates and Jackson 1987, 712)

TL;DR: In this paper, the effect of channel bifurcation and channel linking on donar and receiver river its causes and process of evolution in lower catchment of Mayurakshi River.
Abstract: Present paper aims to find out effect of channel bifurcation and channel linking on donar and receiver river its causes and process of evolution in lower catchment of Mayurakshi River. Toposheets of Survey of India and satellite imageries (IRS 13, LISS III) have used to detect evolutionary process. Field measurements through field survey have done to collect primary data. It is found that just after channel bifurcation, the width of the master stream has drastically reduced and width of the receiver river has increased. This kind of disproportionate stream width character between upper and lower reaches of channel bifurcation and linking sites is called quasi misfit stream as the character of those altered
