Grand River Remeander Sequence
A sequence of eight aerial photos running from 1939 to 1996 show the remeandering of a reach that appears as a straight, probably recently channelized reach in 1939. The location is six miles north of Grant City, Missouri. An animated blue line traces the channel changes.
Note the vegetated bars left behind as meander loops grow. You can also note the severely incised tributaries. Note also the extreme channel shifts from 1983 to 1996, especially in the northern end of the frame.
Note also that there appears to have been rechannelization of some reaches, and I suspect bank armoring, especially where the farm structures are threatened, just west of "1951" in the photo.
