MODELS
The conceptual model for Southern Sierra CZO involves understanding varaibles along three axes: i) elevation gradient, representing alo gradients in climate, regolith properties, soils, ecosystems, and associated processes, ii) spatial scales, and iii) temporal scales. We use a variety of numerical models, as reflected in pulications and the work plan.
Modeling overview
The conceptual model is presented in four panels, illustrated at right, and accompanying text. The panels are: Conceptual model, Processes, Spatial scales and Temporal feedbacks.
The REHSSys panel is linked to a description of one numerical model we are using, the Regional Hydro-Ecologic Simulation System.
Refer to the Conceptual and Numerical models pages for details.
