    The Hydrological IT Framework of the Federal Waterways and Shipping Administration, Germany
    (Informatics for Environmental Protection - Networking Environmental Information, 2005) Michl, Christian; Steinmann, Frank; Reineke, Anja
    The Federal Waterways and Shipping Administration (WSV) in Germany provides as main tasks the safe and easy of inland and coastal shipping transport. To assure these main tasks information technology (IT) solutions and their operation are playing a major role. As central IT support and development section the Federal Waterway and Research Institute with their Information Technology Division are in charge for these developments. Beginning in the year 2000 the hydrological IT framework was redesigned to generate a structured data flow combining the elements of data acquisition, data processing and data distribution providing a standardised intranet solution and an e- Government application. The data acquisition using different telemetric systems as well as on- and offline components were standardised introducing a simultaneous online data transfer system which is connected to regional hydrological data storages. The regional hydrological data storages are grouped in three Citrix Metaframe terminal server farms split in seven server locations and providing the hydrological application software. For the data acquisition the WISKI workbench systems of the Kisters AG is used; existing of different modules for data validation, standardised reporting, stage and flow regulations, tidal and stream flow analysis. Using the Citrix Secure Gateway technology and web interface the internet access for the operation of the system is guaranteed and all components can be used from variable access. Server balancing and WISKI backup database servers provide a high working performance and security. The regional hydrological data storages provide the raw and analysed data to a central hydrological information system for the flood and storm tide warning service, e-Government applications, archiving of historical data and further distribution services.
