tions may be as low as 1.2 with a good data base; higher values should be used 

 as uncertainty increases in estimating the erosion rate. 



The pattern of a meandering river and the expected zones of erosion are 

 illustrated in Figure A-7. Most meandering rivers deviate to some degree from

 erosion as the river meanders migrate down the valley.
