Introduction

The Delft-FEWS configuration guide provides the advanced user of Delft-FEWS with the information required to set-up and maintain a configuration of Delft-FEWS. The objective of the guide is to be used both as a reference manual during the development and maintenance of an implementation of Delft-FEWS, as well as to provide some of the background philosophy on how to go about setting up a forecasting system. It is expected that the reader of this guide has a basic understanding of Delft-FEWS and its structure. If not, the "tips & tricks page for new configurators" might be useful to visit first.

 To understand how to configure Delft-FEWS, a good understanding of the structure of the configuration is required, see the following table:

sectiondescriptionTopics
01 Structure of a Delft-FEWS ConfigurationIntroduction to different parts of the Delft-FEWS configuration.

Elements of the configuration, naming conventions, XML Schemas and schema validation.

02 Data Handling in Delft-FEWSConcepts used for handling data in Delft-FEWS.

Types of Time Series, Time Series Sets, Manual data edits

03 System ConfigurationConfiguration of system components.E.g. Display settings, FewsExplorer, Logging, Permissions, Color schemes
04 Regional ConfigurationVarious regional configuration components which relate to a specific regional FEWS systems (e.g. monitoring locations).E.g. Locations, LocationSets, ModuleInstances, WorkflowDescriptors, Branches, Parameters, Grids, Filters, TimeSteps, Qualifiers, Polygons, Topologies, Thresholds, Historical Events.
05 Module ConfigurationConfiguration of available Modules, e.g. 'module instances'E.g. interpolation of data or how to configure an external model such as ISIS (using the General Adapter Module) including how these can be configured to achieve the required functionality.
06 Workflow ConfigurationConcepts for linking configured modules into logical tasks through configuration of workflows.
07 Display ConfigurationConfiguration of user displays.
08 Mapping Id's flags and unitsMapping information from external data sources.
09 Module datasets and Module ParametersHandling of static module data.
