Describe or draw and label the stages of development of an oxbow lake, from meander bend to cut off to oxbow lake, including the location of cut banks and point bars
What will be an ideal response?
Answers will vary. Figure GIA 15.2B nicely illustrates the process:
a narrow neck is formed when a lengthening meander loops back on itself; the necks narrows more due to undercutting, the stream erodes though the neck forming a cutoff; and, lastly, the oxbow lake forms as sediment fills the area between the stream channel and old meander.
