Sediment Flux Model for Manganese and Iron

This report presents a model of manganese and iron flux from sediments. The reaction kinetics for iron and manganese in the overlying water column are also developed. As shown below, the chemistry of iron and manganese are sufficiently similar so that a common model formulation can be used. The model is an extension of the nutrient and oxygen sediment flux model developed previously for application to Chesapeake Bay. It has subsequently been applied to freshwater lake sediments as well. Thus the model developed in this report is a comprehensive model for nutrients, oxygen and sulfide, and now iron and manganese
