@USGS We use these a lot in Minnesota to collect multiple verticals at a stream cross section. Sediment varies laterally & with depth, so this approach yields truer picture of total sediment load in stream than just dipping a cup. See: https://t.co/HEb
How much suspended material is carried by streams is important info for habitat, channel processes, & reservoir filling. Commonly used TSS methods are biased low, especially for sand-sized sediment. New report examines why, for Minnesota streams: https
