Introduction
Currently, the only graphical user interface to access the Deltares Open Archive is via the Delft-FEWS GUI. In addition, data can be approached via the Geonetwork web client of via THREDDS web server.
...
In the Delft-FEWS application, scheduled and manual archive workflows can take care of archiving the data (sets) from the database. The scheduled archive workflow is generally run once a day and will generally archive the following type of data:
Archived data set | Data set | Data types |
Astronomical data | Observed time series | NetCDF-CF timeseries |
Observed series | Observed time series | NetCDF-CF timeseries |
Surge forecasts | External Forecast time series | NetCDF-CF timeseries |
Forecaster Notes on various level | Messages | text |
Delft-FEWS configuration changes | Configuration | zip (FEWS-configuration) |
Rating Curves | Rating Curves | xml (FEWS PI-rating) |
NWP forecasts | External Forecast time series | NetCDF-CF timeseries |
| Simulations (forecast) | Simulated timeseries | NetCDF-CF timeseries Model States Modifiers Reports |
| Products as handed over to downstream users | Products | Products in original format |
| Local datastore | Snapshot | Local datastore |
Note: External data which is archived elsewhere should in general not be archived within the context of the Delft-FEWS application.
...
Finally, events can play a crucial role in the data management of the archive. Data labelled for a specific type of event may be help longer in the archive compared to data not labelled for an event. E.g. Numerical Weather Predictions may be removed quickly, except for those external forecast that are part of a Flood Watch or training event.
Archive display
All data that is archived can be accessed and downloaded through the Delft-FEWS archive display. The archive display can be started from the Delft-FEWS Explorer from the Tools menu.
...
Note: By double clicking one of the cells in the event list, the event list will be filtered and show only those events that have the same content of the selected cell. To filter for example on historic events, double click in the event type cell where the content is historic event. All cells in that event table column will now have a blue background color indicating there is a filter active. To remove the filter, double click again on one of the event type cells.

If you want to use the data within a different context, you may also copy the data to the normal Import folders, and setup a normal timeSeriesImport run module with idmapping to bring the data into the Delft-FEWS stand alone application registered under your timeSeriesImport run module.

Using archived configurations
These are the 3 ways you can make use of an archived configuration:
- ArchiveDisplay “download and import” button can be used from version 2020.02. It downloads and launches the selected config as a new SA application.
- Menu item "Load latest archive configuration" has two steps : it downloads automatically the latest archived config and then replaces the current config with that downloaded latest config.
- You can use a config downloaded through the ArchiveDisplay in your current SA config, by closing that SA and replacing the config manually. There is currently no way to do this automatically like with the latest config (see previous item)
