Report of my findings:
GloFAS website to know about the methodologies and science behind it:
http://www.globalfloods.eu/general-information/about-glofas/
Look for General Information Section
Available data and services is on Data and Services section.
We particularly interested in the WMS-T service provided here. The URL for the WMS-T is:
http://globalfloods-ows.ecmwf.int/glofas-ows/ows.py
The specific documentation that describes connecting this service to QGIS is here (can be found in Data and Services article) http://www.globalfloods.eu/static/downloads/GloFAS-WMS-T_usermanual.pdf
There is a Map Viewer in the website, you need to register and login to use it. http://www.globalfloods.eu/glofas-forecasting/
We are interested in the following type of datasets:
It is a hydrological analysis, with X available in 5 or 20 year return period.
Format
WMS-T Each timeslice shows probability of streamflow occuring in that spot (raster). It is not clear the magnitude of the stream at the moment and the resolution is not that good for Indonesia.
Specific region to look at
Choose the rainy season, which is at peak around February 2019, particularly near Karawang - Bekasi Districts or other big river basin. Rainy season were around November to May.
It is a point layer that shows location where more forecast information is available. It is not that many in Indonesia.
Format
Point layer with ID. You need to query again to get a table div with more information. The result returned is in HTML format and not easily used.
Specific region to look at
Not that many. In Java, there is only one available in Tangerang, in Cisadane Basin. It should be clickable using IdentifyFeatures in QGIS.
We need to prepare to use GloFAS as our source of flood forecast models. We need to document the location of API access and what kind of data is available.
