![]() ![]() With the cases of alluvial and bedrock meandering channels, the study of Surfaces also develop meandering patterns due to differential melting (e.g., Surface tension (Le Grand Piteira et al., 2006 Davies and Tinker, 1984 Ĭulkin and Davis, 1984 Gorycki, 1973), and channelized flows over ice Rivulets on a plane can also meander due to an instability associated with (Johnson and Finnegan, 2015), and weathering (Pelletier and Baker, 2011). Meandering channels also form in bedrock where the driving processes includeĭissolution (e.g., Veress and Tóth, 2004 Allen, 1971 Zeller, 1967),Ībrasion by sediment particles (Sklar and Dietrich, 2004), plucking ofīedrock (Chatanantavet and Parker, 2009 Whipple et al., 2000), slaking The quintessentialĮxample of a meandering channel is the alluvial river, which forms andĮvolves by erosion and deposition of sediment (e.g., Fisk, 1944 Seminara,Ģ006) and interaction with riparian vegetation (e.g., Braudrick et al., Over different media and across a broad range of scales. Rivers and other channels containing liquid flow develop meandering patterns Please read the corrigendum first before continuing. The absence of recrystallization (depositional analog to alluvial rivers),īends are more likely to be downstream-skewed and channels show lower ![]() ![]() Lateral incision driven by temperature differences between flow and ice. On ice is a function of flow velocity and the interplay between vertical and Observations suggest that sinuosity growth in meltwater meandering channels Weĭiscuss the (ir)relevance of scale in our experiments, which, in spite ofīeing in the laminar flow regime and likely affected by surface tensionĮffects, are capable of shedding light into the processes driving formationĪnd evolution of supraglacial meltwater meandering channels. Wavelength-to-width ratios, and meander bend fatness and skewness). The data also compare well with planformĬharacteristics of alluvial meandering rivers (sinuosity, Migration features, undercut banks and overhangs, meander bend skewness, and meander bend cutoffs. The observations include data from planned centimeter-scale experiments and from incidental Winners will be announced on December 26, 2021.We present a set of observations on meltwater meandering rivulets on ice and compare them (qualitatively and quantitatively) to morphologies commonly found in meandering channels in different media. Submit to followthemeander at gmail dot com. A digital image of each submission must be made by 9pm ET on December 21, 2021. The first 25 submissions will receive a free copy of Follow the Meander and a newly designed National Meander Day t-shirt. Two runners up will each receive a $125 Amazon gift certificate. One grand prize winner will receive a $250 Amazon gift certificate. Categories appropriate for submission include visual artwork, writing, music, short film, culinary and related expressive works. These works should be created between Octoand December 21, 2021. The Meander Challenge encourages you to submit original creative works inspired by National Meander Day which best embody the ideas espoused in the book, Follow the Meander. Silent Thunder Press, publisher of Follow the Meander: An Indirect Route to a More Creative Life, invites you to participate in the 2nd Annual Meander Challenge to coincide with National Meander Day. ![]()
