Retired river Ebro meanders at La Alfranca and Juslibol.

As Andrea had some technical problems I am uploading her work for her:

Definition of meander : in general is a bend in a sinuous watercourse. A meander is formed when the moving water in a stream erodes the outer banks and widens its valley.

  • The Alfranca, Center of Interpretation of the Galachos. The galacho of The Carthusian one, together with those of The Alfranca de Pastriz, and The Hamlet of Ebro, they shelter one of the ecosystems better preserved of Aragon; three former meanders of the Ebro, left by successive modifications of the riverbed of the river, which in Aragon is known by the name of “galacho”. These places constitute an exceptional set of humid zones. As consequence of these special conditions, an exhuberante appears vegetation, where they find refuge an important variety of animal species.
  • Los galachos de juslibol. The galachos, Aragonese denomination of left meanders, are typical examples of the fluvial dynamics of the river, with their variations of course, humid variations in the swellings, areas, bars of fluvial sediments and escarpments in erosive fronts, etc. The studies of maturity in the fluvial channels are characterized by divagantes or meandriformes courses, almost always, with an ample development of the plains of flood and terraces. The meanders characterize by a erosive margin and another deposicional, that finally advance until leaving stretches of the river isolated, by connection of the erosive fronts; these are the galachos. Thus humid areas are constituted, generally with abundance of vegetation and fauna, that usually flood themselves during the avenues of the river. The galachos of Juslibol and Alfranca constitute good examples of the exposed thing, being object of a certain level of protection by the Administrations; it exists, for example, a project of development of galacho of Juslibol like park or natural green zone of Zaragoza.
