The winding process of each river is different because it depends on its flow, the speed of the water and the materials that make it up. They are constantly moving in some areas, such as the plains, so they can form a so-called meander-shaped lake at a certain point. When the meandering flow forms a very large curve, it can cause the course of the river to change. They are called galachos in the Ebro river of Aragon, and they are called swamp along the Mississippi River in the United States. Sometimes they are named after the region of their origin. It is easy to identify or distinguish from other types of rivers, because its main characteristic is the very obvious meandering curve it forms in the riverbed. When the advance of the embankment in the convex zone is combined with the retreat of the concave zone, the course of the river begins to migrate and meanders occur. In the recesses erosion dominates, and it is obvious how the embankment recedes due to the centrifugal force. The sediment is usually deposited in the bump in a zigzag fashion and then moves from there to the shore. In the rivers that flow through the floodplain, meanders are usually easier to form when the slope is small. There are three types of tributaries: braided, straight, and curved or serpentine. Having known all this about what are the meanderings, characteristics, types and details, we encourage you to learn more about freshwater with these other items AgroCorrn on Why are important rivers and lakes, the pollution of lakes and rivers: causes, consequences and how to avoid it and The most polluted rivers in the world .Meanders are used to characterize specific types of rivers based on their design. Hoces del Río Júcar in Alcalá del Júcar (Albacete), Hoces del Río Cabriel (Cuenca) and Hoces del Río Duratón (Segovia).The meander of the Say or the Old Mother of the Bogotá River, located in Fontibón, was formed from the artificial modification of the old Bogotá riverbed. This meander was declared a Distral Wetland Ecological Park in 2004.In the Matanza-Riachuelo river we find the meander of Brian (Buenos Aires, Argentina), which stands out for being the only meander that has remained after the works carried out to rectify the channel of the Riachuelo.The El Melero meander , located on the eastern limit of the Sierra de Gata, is formed by the Alagón River, as it passes through the Hurdes region (Cáceres).Among the main parts of a meander, we can indicate that the external part, due to greater speed and turbulence, is the erosive zone while, the internal part is that of sedimentation.The formation of meanders differs according to the river, as it depends on factors such as flow, current speed and the material composition of the channel. It is also taken into account for its classification: according to the classification of channels by Miall (1977), meandering channels are those with a sinuosity> 1.5 (sinuosity index). The course of these meandering rivers is unstable, being able to form a horseshoe or oxbow lake.
