摘要:
A time-dependent dispersion model based on Lagrangian correlation and calibrated using laboratory data is applied to predict dispersion in four narrow streams in Hong Kong. For early stages of dispersion, the model parameters were completely known from laboratory results. For large times, the Lagrangian time scale t0for dispersion was estimated by a trial and error procedure. Satisfactory predictions have been obtained for the test reaches considered.
