Portal of PCGAP

schematic

How the web portal is structured, to address the goals and objectives of PCGAP.

    The specific tasks of PCGAP are to:

  • Support the development and operation of distributed, landscape/hydrological models that are sensitive to climate and land cover and land use changes from field to watershed to water basin scales.
  • Provide a secure repository for the georeferenced data for Espírito Santos required for model development;
  • Facilitate updating and augmenting of the datasets as appropriate

     The overall "logic"  of PCGAP  as represented on this web portal focuses first  developing the overall strategy and execution of the toolset used to "set the table" to evaluate the management issues. [figure to be developed

Strategy provides the overall logic and primary description of the tools used in the basic dynamic information framework (DIF).

The first step is to develop the "engine," or dynamic information framework, for executing the analysis of issues.

River Basins  provides the general description of the region, and then develops the base topography, soils, and landuse information required by the models, and available for general use. It provides the repository for the information used.

Data to Models provides the mechanics of how the overall information was developed, models setup and calibrated, and the computer portals used.     

     Then, with the mechanics in place, the DIF is applied to three primary resource issues. Each builds on the previous.

Weather to Rivers addresses  the issue of How is “weather” (rainfall, heat) is  translated to soil moisture, ET, and ultimately runoff and discharge across the landscape of Espírito Santo, at different time and space scales? 

Landuse builds on the understanding of the basic hydrology of the region (from Weather to Rivers)  to address the issue of,  "How do changes in the landuse affect the movement of water across the landscape?"

Sediments combines the understanding of hydrology and landuse changes to address the issue of "How do changes in landuse and water movement effect the mobilization of sediments?

Decisions provides the platform for developing the (future) Decision Support System (DSS), with the overall information and toolset. That said, this is only the first step, towards broader engagement in more specific issues.

     The project description is also provided in the Final Report. Parts 1 and 2 of Progress Report #4 is available here, and Part 3 is here.
