The inside bend is shallower with a gentle slip-off slope made of sand or shingle that is brought across from the outside bend by the helicoidal flow of the river. Almost all rivers have sections that include meanders. For example, when I started working in large format I was lucky enough to get hold of a 150mm Rodenstock Sironar S, widely recognised as one of the best large format lenses available.

As a river winds over the earth’s surface, a greater amount of erosion occurs on the outer river bend, where the flow of water is the fastest. Observe the path of the barrel as it floats down the river. Lower course: the section of the river near the sea, where deposition is the most important process and the valley becomes wider and flatter. The damming events were caused by debris flows triggered by glacial advances on … The increase in the flow of any river is caused by the large volume of rainfall in its basin, which would pro b- ably change the physical parameters of the riv er involving the changes in the depth due to bank erosion’ taking place and width of flow [11]-[14].
