    Organic matter that deposits in the sediment of aquatic systems drives many chemical reactions, the outcomes of which determine water quality and carbon burial. The variables, parameterisations and applications of all contemporary numerical sediment models were analysed. One of the most important challenges identified is aligning modelled organic matter transformations with measurable parameters and theoretical mechanisms. A synthesis of conceptual models of organic matter was used to build a model that parameterizes mechanisms according to fundamental thermodynamic properties, which included features found in previous models. The new model captured the redox sequence, using fundamental thermodynamic properties and measurable parameters.
