Sediment Concentration and Attenuation Coefficient October 2009 Storms at Kickapoo (05579630)
1,636 mi2 drainage area
Up to ~25 % sands in suspension
Side-looker: on-going problems with debris on instrument
Wake zone?Site 2:One of the largest contributors of sediment to the Illinois River
Partial cleanup of data (negative slopes taken out)Results with only two cells used
-no near field correction
