Calhoun Models - Soil Science / Pedology
CN reforest dynamics
Coupled dynamics of tree and soil C and N during reforestation following land abandonment
Calhoun reforestation was unique: 30% biomass was lost after age 35. Models are used to explore explanations of this behavior.
Plant-soil feedback
Bistable plant-soil dynamics and biogenic controls on the soil production function
A coupled soil-plant model was developed, exhibiting bistability driven by positive feedback between vegetation and soil.
tRIBS
tRIBS Model
tRIBS (TIN-based Real-Time Integrated Basin Simulator) is a fully distributed physically-based hydrologic model.
tRIBS-ECO
Triangulated Irregular Network-based Real-time Integrated Basin Simulator-Erosion and C Oxidatition
Spatially- and depth-explicit physically-based model of hydro-geomorphic processes and of soil organic carbon dynamics.
