Interactive APEX (i_APEX) USERS GUIDE USING APEX2110 and APEX0806
The interactive APEX (i_APEX) is a user friendly interface for the physical process and environmental fate model, Agricultural Policy/Environmental eXtender (APEX) (Williams et al., 2006, 2008; Williams and Izaurralde, 2006; Gassman et al., 2010). I_APEX is programmed in C++ and performs automatic management of the input data, execution of each APEX run, and data storage of selected model outputs using a single Microsoft ACCESS database to manage both the input and output data required for APEX simulations. The model provides a well organized easily understood interface with definitions and help assistance for most variables. The greatest advantage of i_APEX is in its ability to perform multiple model runs (over 100,000 runs in a run-set) in “batch†mode for each record selected in the Control Records Table. This provides a tremendous advantage when attempting to model multiple scenario permutations for a single field or small watershed, or in modeling thousands of agricultural fields and other land-uses over a large area such as a river basin or region.
