Abstract

An algebraic turbulence model has been developed on the basis of classical ideas of mixing length and damping functions with the intention of engineering application. The empirical constants introduced by this closure have been calibrated with data from meteorology, oceanography and laboratory experiments published in the literature, yielding a set of parameters not tuned to a particular system. Long-term simulations with this turbulence model implemented in a finite-difference numerical model reproduce all the important features of field data. Thus, the general applicability of this model as a predictive tool for estuarine flow and transport processes is demonstrated.
