![]() The associated features or landforms of a meandering river system are as follows:Īssociated Features of Meander River System And if the value of the index is more than 1.5, then it is known as the meander river system.Īssociated Landforms of a Meandering River System If the value varies from 1-1.5, the river has a sinuous course. ![]() If the value is less than or equals one, then the river is straight. The sinuosity index is determined by the actual length of the river divided by the shortest path. Whether a river will flow straight or become sinuous or meander is determined by its Sinuosity Index. ![]() The height of the meander between its own valley and the sinuous axis. The distance between two meanders from one crest to another. In a meander, the secondary flow (the force that exists between centrifugal force, which points outer bend, and the pressure forces pointing to the convex bend) dominates the irrotational flow (where fluid velocity is low in the outer bend and higher in the inner bend).Ī meander river system has several components like. The area within which the meander shifts is known as the meander belt.Įach of the bends of the meandering river system gets deeper, and after a certain point in time, they cut the neck and start to follow in the new path. After the formation of the point bar, the meandering course of the river starts to shift within its valley floor or floodplain. Therefore, a point bar is formed thereon the inner bank. The river cuts and erodes its outer bank or concave bank and deposits the material on its inner or convex bank. As a result, the river's flow is obstructed, and it takes a winding course, and the bends get deeper along with the time. In the middle course, the river starts to deposit its load on the basin itself. How are the Components of a Meander River System Formed?Ī meander river system generally forms due to the natural forces acting on a river during its course. The river flows again in a straight path. The lake thus formed is known as an oxbow lake. For this reason, the bends or the curves of the meander get deeper day by day, and after a certain point in time, the goose-neck formed in one of the bends gets cut off, leaving behind that bend as a standalone waterbody. The meandering river system is formed due to the deposition process of the river.Ī river generally erodes non-homogenous materials present in the bedrock or the bank's walls unevenly that is why irregularities are found in the meandering river system. The term meander has been derived from the Greek word “Maiandros,” the old name of a river in Turkey, Menderes. Thus, sinuous curves or bends are formed, known as the meanders, and the course itself is known as the meandering course. In its middle course, a river generally starts to erode one bank and deposit on the other. Look at the diagram to know how a meandering river system looks like: ![]() What Do You Mean by the Meander River System? In this article, we are going to discuss a meander river system and its components. Some of the typical landforms and features of this part of a river course are meanders, oxbow lakes, flood plains, levees, etc. ![]() Here, the river transports the eroded material while continuing with lateral erosion. The middle course of a river starts when it enters into the plainland then, the slope suddenly gets reduced. As we all know, the upper course is close to the river’s source, which is mainly in the mountains (for snow-fed rivers). A typical river course can be divided into the upper course, middle course, and lower course. ![]()
