The lower section of R. Kam is showing signs of an old stage because of the presence of meanders. Meanders are bends or loops in a river, and they are formed when a river flows over a plain. The flow of the river erodes the banks on the outer bend and deposits sediments on the inner bend, causing the river to change course over time. As the river continues to flow, the meanders become more pronounced, and the distance between the outer and inner bends increases. This process is called lateral migration and is a characteristic of an old stage river. Therefore, the presence of meanders in the lower section of R. Kam indicates that the river has been flowing for a long time and has reached an old stage.
