Particulate organic matter export from three headwater streams: discrete versus continuous measurements. [pdf]Paper  abstract   bibtex   
Particulate organic matter (POM) export from three small headwater streams was estimated using continuous and grab measurement methods for 2 yrs. Total annual POM export estimated from continuous mesurements was always greater than estimates made from grab samples. Continuous export samples were collected using a weir and gaging flume connected to a Coshocton proportional sampler designed to deliver 0.6% of discharge into a series of three settling barrels. The settling barrels removed a consistent proportion of POM (85-87%). The inability of the discrete method to adequately sample storm and bedload transport underestimates total annual export.
