摘要

Bubbly Creek was historically used as a drainage channel for the wasteresulting from Chicago’s stockyards. Nowadays there is flow in the creek only duringrainfall events resulting in Combined Sewer Overflows (CSO) and water quality is avery important issue, particularly during the summer months, when the dissolvedoxygen levels are extremely low and sediment oxygen demand is expected to be large.Due to the particular flow regimes of the creek and the conditions of thebenthic sediments in the bed, a special BOD-DO (Biochemical Oxygen Demand -Dissolved Oxygen) water quality module was developed and implemented into thetwo-dimensional depth-averaged numerical model STREMR-HySedWq. Theapproach illustrated represents a substantial improvement to the state-of-the-art ofwater quality modeling methodologies.The model was able to capture the key processes and provide usefulpreliminary results for the two following scenarios: [1] CSO events, for which themodel was coupled to a one-dimensional cross-section-averaged BOD-DO waterquality model, and [2] potential “purification” solutions, such as flow augmentationand supplemental aeration, with the goal of increasing the DO levels in the creekduring dry weather periods.
