Data to Models


How are the data bases organized and processed for the models, and how are the models calibrated and validated, and made available?

     For the purposes of this project, two models need to be developed for the different scales. For the issues represented by the 2 project watersheds (Jucú, Santa Maria da Vitória), the DHSVM (Distributed Hydrology Soil Vegetation Model), at a scale of 150 m, is used. At the Espírito Santos State scale, the VIC (Variable Infiltration Capacity) model, at a  resolution of 1/12o (about 8km),  is used. It makes sense to develop the state-level VIC model, at essentially the same time, to take advantage of considerable overlap in data requirements and personnel available, as well as the importance of state-wide issues. To further meet stakeholder requirements, it is likely that additional (sub) models for agriculture and irrigation will be required, as well as operating rules for dams and other infrastructure.

     As summarized in the section on The Models (under Strategy), each model has a detailed set of requirements for data. The section on Dataframe Development summarizes how the data, represented primarily in the section under River Basins, is processed and made available to the model computer codes. Then how each model is setup is summarized, with the capability of the models rerpesented by the calibration/validation (cal/val) process. Finally the Computer Portal is provided.
