  1. Integrated Hydrological Data Management- Software Systems for Hydrological Data Archives,Water Observation and Information Systems byGrad. Geographer Matthias Egeling Germany

  2. Demands on Software Systems in Hydro-Meteorology (1) Demands • todays information technology represents an ideal base for hydrological information systems • integrated views to: • - Data acquisition • - Data evaluation • - Dissemination of verified hydrological and ecological data sets • with interfaces to: • - hydrological modeling • - water management techniques • - geographical localisation (GIS) • public information (Web) • water quality measurements

  3. Integration and Interfaces Monitoring systems WISKI Hydro-meteorological workbench Model Integration Management and Supply of Information by Web Water Quality Data Management Interface to Geographical Information Systems (GIS) Central Database

  4. Demands on Software Systems in Hydro-Meteorology (2) Demands • linked informations of different measured hydro-meteorological and environmental parameters • …knowing the dataflow from the origin of the measured values until the presentation of the results… • the user must be supplied with significantly information about data quantity and quality and the processing history of data values in addition to the value itself • …every calculation is only as good as their source values… • user-acceptance of the software through user-interfaces which follows the daily workflow

  5. Hydrological Workbench WISKI longterm values maximum monthly maxmimum longterm values mean monthly mean longterm values minimum monthly minimum Hydrological Workbench

  6. WISKIExplorer Hydrological Workbench f.i. context menu time series: Control center WISKI-Explorer • hierarchic structure • sorting by- station name - station number- station types…. • efficient management and adaption of single values and mass data f.i. context menu stations:

  7. Data Collection and Import WISKI Automatic Import Scanning of import folder, converting and importing Manual File Import over 60 various data formats Import devices (OTT Vota, SEBA HT 100, AquaCalc, PSION) Hydrological Workbench WISKI DIGIT Manual input Analog / Mechanical Strip Charts BIBER & & Excel/Access or clipboard Discharge Measurements SODA Telemetry System

  8. Standardised Hydrological Correction Tools Hydrological Workbench • Graphical Correction Tools: • Gap filling algorithms • Interpolation • Filtering algorithms • Formulas • Regression and Statistics • Models • Comparison to neighbouring stations • All tools are available in a standardisedinterface, the time-series-graph

  9. Working with a Second Gauge Hydrological Workbench • Quality Control Graph with • 1st Gauge (blue) • 2nd Gauge (red) • Difference (green) • Observer gauge reading (yellow points) • Standard Remarks by the Observer Graph and Data by Baden-Württemberg Institute For Environmental Protection (LfU)

  10. Multi-Tier architecture for Time Series Management Printer Database 2 Database 1 Solutions Web-Tier Webclient 1 Webclient 2 Webclient 3 Application/module-Tier Webserver TCA TCA1 TCA2 TCA3 SODA Telemetry System AIS & Report Server Server-Tier Central server TSM Calculation Server TSM Calculation Server TSM Calculation Server TSM TSM Storage-Tier File server process control systems with real-time data

  11. References (1) References • WISKI is present now in Germany, Austria, Switzerland, Sweden, Scotland, England and Wales, Ireland, Netherlands, Belgium, Luxemburg, Kosovo, Italy, Spain, Canada and the United States of America • Our basic technology is used by more than 300 different installations and more than 2000 users. • Such a large number of customers and requirements can only be handled with a special strategy: • - Concentrate on product development • - Keep the product modular and flexible • - Keep in close touchwith the customers and the technological development

  12. References (2) National Archive 32,000 Stations 2.6 Billion data points 60 GB database 300 concurrent user 600 in total WISKI References We have Clients from 1 User and 70 measuring points and stations up to… The HARP Project of the Environment Agency, the new national hydrometric archive of England and Wales

  13. Many thanks indeed! Thank you very much for your patience and attention!
