Mississippi Basin Carbon Project Science Plan

Modeling

An open-file report will present a "first-cut" carbon budget for the Mississippi Basin. Initial model development will include testing of landscape indices (such as those used in TOPMODEL) as indicators of areas of erosion and deposition in selected basins, and upgrading of code for existing USGS global CO₂ models. Subsequently, we anticipate developing links between landscape indices and soil model parameters such as those used in CENTURY. Global modeling will be extended to include explicit treatment of land surface disturbance and soil development, and land characterization schemes will be developed to bridge the gap between ecological carbon cycle models and those developed by this project. Results of these modeling activities will be published in journal articles.
