  • A suite of 40 morphometric variables has been measured on 57 sections of freely meandering channels from 33 rivers. These objective variables are computed from digitized traces of the channel centerline and include measures of sinuosity, meander
  • wavelength, curvature moments, meander asymmetry, and pattern irregularity. Principal components analysis reveals that morphological variations between freely meandering streams can be resolved into four factors related to meander wavelength, meander
  • irregularity, sinuosity, and large-scale wandering of the meander axis.

  • Channel geometry ; Fluvial processes ; Meander ; Methodology ; River bed ; Stream ; United States of America
  • This study, which is concerned solely with single-thread channels, focuses on resolving problems in measuring the two basic properties of meander planform: the degree of meandering (normally measured by sinuosity P) and the size or scale of meanders
  • (typically measured by wavelength L). Most meanders are irregular and the unambiguous identification of inflection points is problematic. The main goal of this study is to present an objective method that should be capable of providing consistent
  • and reproducible results even when applied to the irregular and complex meanders commonly found in nature.

  • River meanders present the most frequent planform of lowland rivers. Their formation on poljes mostly depends on flood water regime. Flooding dictates space-time zonation of meandering processes, of which the existence of active or passive phase
  • of planform modification depends. Studied meanders of the stream Dobravka on the Radensko polje represent an excellent example of meanders (re)formed by meandering processes (inter)actions. - (L'A.).

  • This paper examines evidence of complex behaviour and, in particular, possible operation of self-organized criticality in meandering systems, using primary evidence of a field study and also evidence from a kinematic model. The range of meander

  • A cellular model of river meandering
  • Chenal anastomosé ; Cours d'eau ; Géométrie hydraulique ; Modèle ; Méandre
  • Braided channel ; Channel geometry ; Meander ; Model ; Stream
  • This paper describes a new method to simulate river meandering within a cellular model (CAESAR). A novel technique for determining bend radius of curvature on a cell by cell basis is described, that importantly allows regional information on bend
  • curvature to be transferred to local points. This local curvature is then used to drive meandering and lateral erosion through 2 methods. Key difficulties are identified, including the deposition of material on point bars and cut off development
  • , but the method illustrates how meandering can be integrated within a cellular framework. This demonstrates the potential to produce a single model that can incorporate both meandering and braiding.

  • The Geul River, located in the south-eastern part of The Netherlands, is a meandering river with a planform shape characterized by large loops consisting of multiple bends. The AA. evaluate the effects of groundwater flow on the shapes of meanders
  • as a possible explanation for the multi-bend loops, using a combined meandering-groundwater computer model. In the model seeping groundwater enhances bank erodibility.

  • The distribution of large woody debris (LWD) was studied along the concave outer bend of 3 meanders in the Ain River. The Ain River is a sixth-order channel dominated by a gravel-cobble bed substrate that meanders through a floodplain covered
  • largely by riparian forest vegetation. The total LWD deposited along concavities was most strongly controlled by meander-bend geometry. Findings from this study are applicable to restore alluvial forests along French rivers.
