Management decisions often regulate nutrient loads in streams based on information from regional to basin-scale models which can be limited by sparse datasets. Research is needed to assess stream nutrient kinetics to better inform water managers of the assimilative capacity of streams and further assist in development of downstream protection values and total maximum daily loads (TMDLs). This study employs the Tracer Additions for Spiraling Curve Characterization (TASCC) method (Covino et al. 2010) to examine nutrient kinetics in a small spring-fed north Florida stream. Applied methodology investigates spatial and temporal variability in nutrient kinetics under various initial conditions associated with energy input fluctuations related to diurnal changes and the presence/absence of tree canopy coverage. The TASCC method provides an efficient way to fully characterize the stream reach nutrient uptake velocity and rate models through analysis of conservative (Cl) and reactive tracers (N, P). Overall, this study investigates the characterization of nutrient kinetics and provides a basis for further studies in a variety of stream systems. |
