Abstract: A mathematical model of estuarine sediment is developed using rate coefficients and field measurements. The model has a particular emphasis on the sulfur cycle and includes specific chemical components of dissolved oxygen, soluble organic carbon, sulfates, free sulfides, total sulfides, sulfide capacity, sulfur, and pyrite. Different levels of sediment organics (OCS) and turnover rates (RST) are mathematically imposed and the subsequent levels of chemical components are determined after a 210-day period. General chemical properties are identified for a RST-OCS plane.
