How to import longitudinal time series from SOBEK-CF models
When running a SOBEK model the "SbkBatch.exe" module is used as a model adapter to convert the FEWS-PI XML data to native SOBEK files, start the SOBEK model(s), and convert the SOBEK native output files back to FEWS-PI XML files. the FEWS General Adapter is used to export and import FEWS-PI XML data from and to the FEWS datastore, as well as starting the SbkBatch.exe module.
One type of data that can not be handled by the SbkBatch.exe model adapter is longitudinal time series data. In order to import longitudinal time series from a SOBEK model run we need to use the "PostSobekModelAdapter"; this is a SOBEK model adapter originally made to handle data for SOBEK-RE models. It can however also be used to import longitudinal time series from SOBEK-CF models.
In this document we will discuss the setup of a PostSobekModelAdapter and the configuration of Branches required to store longitudinal time series. As example, the configuration of the Keelung and Hsientien rivers from the "TanshuiRRCFKT" SOBEK-CF model is used.
FEWS Regional Configuration
DELFT-FEWS is a location oriented system. All time series data must be referenced to a (geographic) location. Scalar time series need no additional information. For longitudinal time series data, each point in the vector must be referenced to a location in a branch structure. This location must be identified by its coordinate within the branch (chainage), and may also be defined by its geographic coordinates within the coordinate system used. An example of a branch is given below.
The FEWS configuration file that stores all information of branches is called the:
Branches 1.00 default.xml
More information on the branches file can be found on:
http://public.wldelft.nl/display/FEWSDOC/05+Branches
Each new branch added to the Branches XML file has an ID, this ID must refer to a location ID in the Locations definition.
