Developing and adapting soil process submodels for use in the pedodynamic ORTHOD model

The development and structure of the model, designed to simulate processes involved in the formation of a Typic Haplorthod, are discussed. To obtain data for the development and validation of various submodels of this "pedodynamic' model, three detailed monitoring sites were installed in a boreal forest in the Adirondack Mountains near Tupper Lake, New York. These provide quantitative representations of water movement, solute movement, soil temperature, mineral dissolution, microbial decomposition of organic matter, ion exchange, and chemical speciation and precipitation. -after Authors
