Abstract

Presented by: Elijah Schukow – Graduate Student at Illinois State University, ejschu2@ilstu.edu Co-authors: Eric Peterson, William Perry, Catherine O’Reilly, Jack Wang Abstract: Increased sediment introduction and transport in streams negatively impact reservoir quality, water quality, and ecological diversity. Deleterious effects include reservoir filling, water pollution and ecological impairment. Sediment transport typically takes place during storm events. Phosphorus can adsorb onto sediments leading to elevated transport and introduction in streams. Increased phosphorus introduction into waterways is a main driver of algal blooms and hypoxic conditions. The goal of this study is to determine if turbidity, total suspended sediments, and phosphorus exhibit similar transport behaviors in an agricultural watershed. Three years of data is available at the Six Mile Creek watershed located in McLean County Illinois. Multiyear analysis of total suspended sediments, turbidity, and phosphorus data show that both turbidity and total suspended sediments display a correlation ranging from weakly to strongly positive with total phosphorus and a R-value ranging from (0.4015 – 0.8570). Further analysis of this relationship can be conducted by using hysteresis analysis. A further understanding of suspended sediment and phosphorus transport mechanics and introduction can be utilized by farmers and agricultural managers to develop more sustainable land management practices and ultimately mitigate the amount of suspended sediments and phosphorus introduced into surface waters. Biography: Elijah obtained his undergraduate degree in geology with an emphasis in hydrogeology from the University of Oshkosh Wisconsin. He is currently a second-year master’s student in the hydrogeology graduate program at Illinois State University. Elijah’s research interests include sediment and nutrient transport in surface waters and watershed response to storm events.
