Effects of Season and Waterbody on Transparency Tube Estimates of Suspended Sediment in Large Rivers
JOHNSON, KS; FANG, Y & CHANG, T
Abstract
This paper reports the measurement (N>132) of the effect of river and season on transparency in
cm and Total Suspended Solids in mg/L in a navigational pool of the Ohio River and one of its tributaries, the
Muskingum River. Both river of origin and season affected water transparency. The transparency-TSS relationship
was stronger in spring (R2 = 0.894) than autumn (R2 =0.710), with an overall correlation of R2=0.86 for N=93
observations in both water bodies and seasons. Regression equations for the transparency-TSS relationships for the two
rivers under low (autumn) and high (spring) flow conditions were developed. Our study demonstrates that properly
trained volunteers can assist with rapid assessment of water turbidity from suspended solids in large rivers, reservoirs
and lakes, but seasonal calibration of these measures will improve accuracy of sediment monitoring and management.
