The paper discusses a one-dimensional circulation model for the marina. Tides are modeled as long waves and are assumed to be much longer than the marina. This circulation model is coupled to a conservation of mass model for a conservative pollutant. The pollutant model allows an examination of the marina flushing characteristics as well as the response to point, uniform, and time dependent sources of pollution. A numerical sedimentation model is also coupled to the circulation model. A suspended sediment model is developed based on the settling velocities of the sediment. Deposition is determined from conservation of sediment mass and residence times.
