METHODS OF DATA COLLECTION 



The hydrology and hydraulics field program was conducted to provide 

 information for the evaluation of gravel removal impacts on the physical 

 characteristics of the river within the study reach. Three consecutive 

 days were available at each of the 25 study sites for collection of these 

 data. The site visit was during the summer when the water level was rela- 

 tively low so that the channels could be more easily crossed. Details on 

 the procedures used can be found in APPROACH AND METHODOLOGY.
