Field verification for a reaeration model in streams

Oxygen transfer at surface of lakes and streams is an effective process for the environmental quality of the aquatic ecosystem; thus, the amount of oxygen transferred to the water body should be careful estimated. The paper propose a new hydrodynamically-based model for reaeration rate estimation that provides an estimation of the thickness deltac of the concentration boundary layer at air-water interface, which is assumed to control reaeration process. The proposed model has been verified using a large amount of field data; comparison between model predictions and field data produces a lower spreading than other literature formulas that were previously tested using the same data set.
