Abstract:

Reduction of instream total phosphorus to near background levels of 0.05 ug/L, under a preliminary TMDL, have not provided the expected reduction in macrophyte coverage and increase in low dissolved oxygen (DO) in the East Canyon Creek, Utah. A field program provided data to develop and calibrate a model to identify and assess control strategies to increase DO levels to restore the creek to beneficial uses. The steady-state model, DIURNAL, was selected because it includes parameters such as carbonaceous biochemical oxygen demand (CBOD), DO, organic nitrogen, ammonia, nitrite++nitrate, simple phosphorus, conductivity (conservative tracer) and associated transformation processes (kinetics) and it computes diurnal DO. A site specific reaeration equation was developed. Model results show that non-traditional management alternatives (establishing riparian canopy, creek restoration, flow augmentation), can provide improvements to DO levels in the Creek of up to 2.0 mg/L rather than implementing costly WWTP nitrogen controls.
