Characterizing The Concentration, Duration, And Frequency Of Turbid Events In Tennessee Streams: Potential For Macroinvertebrate Impairment, Robert Ryan Woockman
Characterizing The Concentration, Duration, And Frequency Of Turbid Events In Tennessee Streams: Potential For Macroinvertebrate Impairment, Robert Ryan Woockman

The impairment of lotic systems due to siltation is one of the most common factors leading to a stream being placed on the 303d list. Once a stream reach is placed on the 303d list, a state’s environmental regulatory agency must then develop sediment total maximum daily loads (TMDLs). However, a deficiency exists in available methods for assessing biotic response to siltation, creating the inability to set TMDLs functionally related to cause of impairment. Water quality sondes can collect voluminous amounts of turbidity data and stage data at intervals that can be used to characterize concentration, duration, and frequency (CDF) …

Correlating Suspended Sediment And Biological Metrics In East Tennessee Streams, Jeremy Robert Mefford
Masters Theses
Excessive suspended sediment is a major cause of pollution in US streams, as reported by the USEPA. Also known as siltation, having excessive sediment in a stream harms the biology of a stream through directly affecting living organisms, but also through harming natural habitats. Too much excessive sediment leads to a stream being declared impaired. Testing for suspended sediment levels is difficult and time consuming, so indirect methods of testing for total suspended solids (TSS) are desirable. While turbidity has been an oft used TSS surrogate in the past, this study takes the next step of looking at potential relationships …
