Distribution of Oil Pollution Residues

A new mathematical model is proposed for the simulation of the distribution of oil pollution residues along the length of a closed estuary. The model consists of a dual system of continuous stirred tank reactors with oil pollution residues initially suspended in the aqueous phase and being transferred to the sediments by settling. An effective numerical procedure was used to solve the system equations on a CYBER computer. Experimental measurements of oil pollution residues in the Parramatta and Duck Rivers, Australia can modeled by this method. The parameters in the model were evaluated using a Simplex optimization routine. The extensive experimental survey of these rivers indicate they conservatively contain 8,000 ton of oil pollution residues which will require several decades for complete oxygenation. The new modeling techniques proposed for the sediments are capable of handling single and mutipoint sources of pollutants and will assist in water quality management of closed estuaries.
