Abstract: A mathematical model is developed to simulate the movement and fate and of the biomass in an estuarine environment. The biomass is represented by a number of individual particles. The particles can be inserted into any location within the estuary and can be monitored at any desired locations. The advective movement of a particle is based on the one dimensional velocity obtained by executing a separate hydrodynamics model which is constructed on the conservation principles of mass and momentum. The dispersive movement of an individual particle is carried out so that the aggregate movement of the particles resembles the dispersion of a soluble constituent. For the aggregate of particles to manifest turbulence-induced dispersion, quasi-three dimensional expansion of the one-dimensional velocity is necessary. The developed model is applied to the Sacramento-San Joaquin Delta, one of the most complex estuaries in the western United States. Results of the model application are presented.
