begun on all sediment and water column Seiraples. The benthic 

 macroinvertebrates have also been analyzed for their heavy 

 metal content. 



FUTURE ACTIVITIES ; Work is anticipated to begin on modeling 

 the fluvial mechanics of the upper river's channel and flood- 

 plains; e.g. determining the rate of channel meander migra- 

 tion which has a major influence upon the concentration 

 of heavy metals present in the river during runoff.
