ABSTRACT
This chapter addresses the need for the integration by combining current generation geomorphological models with established carbon dynamics models to examine the interaction between soil redistribution and carbon fluxes between soil and atmosphere on agricultural land. The main characteristic of the spatially distributed soil erosion model (SPEROS-C) model is the three-dimensional representation of the soil landscape. The water erosion model used within SPEROS-C aims to represent the effects of topography and catchment heterogeneity on the dynamics of sediment redistribution by overland flow. Tillage erosion is recently identified as an important contributor to soil redistribution in rolling topographies. Tillage erosion experiments have shown that soil is translocated and dispersed during soil tillage. Tillage not only leads to the redistribution of soil and soil constituents, it also results in a net loss or gain of soil at specific landscape positions. SPEROS-C uses a relatively simple carbon dynamics model structure.
