Peakall et al. (2012) demonstrate that submarine channels exhibit a global latitudinal variation in sinuosity. In contrast, alluvial river channels show no such global variation. However, a variation of sinuosity with latitude has been observed for bedrock-floored river channels between the equator and the mid-latitudes in the western North Pacific (Stark et al., 2010). Such variation has been linked to rock weakness influenced by frequent heavy rainfall and associated flooding, in turn associated with typhoon strike frequency (Stark et al., 2010). Channel sinuosity is greatest in the...
