Designing the Forecasting System

The next step in building a FEWS application is to make a rough design of the system. This design can be very simple but it should include all major steps and actions that will be included in the system. In our test case we will make a simple FEWS that consists of the following tasks;

  • import observed hydrological and meteorological data, and import forecast meteorological data
  • fill gaps using interpolation
  • run a rainfall- runoff model
  • show the results in a report

The FEWS should also check the imported data on outliers and extreme values. In a simple schema we will show the four main tasks.

Of course each of these tasks can be split into smaller elements. The import task (or workflow) will for example import data from different sources; it is best to import data from different sources in separate elements. Each of these elements will be a Module Instance, i.e. a configuration of the FEWS import module.
