Field Photo: A Bend In A Himalayan River

I took this picture of a meander and a point bar deposit on the road from Munsiyari to Bageshwar along a section of the Sarayu river traversing a section of the Lesser Himalayas. It shows the classic meander landform of cut erosion along the outer bank  and deposition along the inner bank. Land pressure is high in the Himalayas too and the point bar deposit has been cultivated.

Another view of the meander and the point bar deposit.

The cultivated portion of the point bar seems at a slightly higher elevation than the present river channel and I think it indicates that the river has incised a little leaving an older point bar stranded. A younger point bar is developing in front of the cultivated portion made up of gravelly sediments.
