A modular IT architecture for integrated water management

1. A modular IT architecture for integrated water management BALWOIS 2006; Mai 23-26 2006; Ohrid/Macedonia Dr. Denis Havlik

2. Who are we? • Austrian Research Centers (http://www.arcs.ac.at/) • Biggest Austrian non-university research institution • 900 researchers, 100 M€ • competences from nanotechnology to wind tunnels for testing trains, biotechnology, life-, material-, medical- & space-science, information technology… Watermark multidisciplinary team: • Biogenetics - natural resources/water (http://www.seibersdorf-research.at/) • IT - Environmental informatics (http://www.smart-systems.at) • System Research – Environmental planning (http://www.systemsresearch.ac.at/)

3. Watermark – basic idea Knowledge Tool Levels of data aggregation WATERMARK EU National Regional Communal GIS-Modelling Other relevant data (e.g. management, meteorology etc.) User Information generation Regional Systems WISA

4. Watermark - objectives • Innovative and applied solutions for comprehensive information and knowledge management to support water management planning (according to the EU Water Framework Directive) • Standard-compliant (OGC, ISO 19XXX) • Scalability & ease of deployment: • Server-based + thin (web) client • Modular architecture, reusable elements • User levels and access rights • ASP model (Application Service Provider) • Value added Services: • Risk analysis & decision support • Intelligent GIS-based data models • Presentation and visualisation of results • Functional operation and analysis tools

6. WATERMARK use cases (1) • Defined pollution to soil/groundwater (punctual infiltration of contaminants) Risk assessment, contaminant transport • Development of additional groundwater capacities    Simulation of groundwater management scenarios (well locations and withdrawal quantities) • Protection zones, sensitive areas Determination of flow curves (isochrones), vulnerability analysis, land use of the catchment area

7. c a 3 b Watermark examples

8. WATERMARK – use cases (2) • Trend analysis and (early) warning system Trend analysis for ground water bodies (sustainability of quantitative and qualitative state – interdiction of deterioration), alert when exceeding a maximum allowable deviation • Analysis of risks and counteractive measures (expert mode) •    Scenario analysis for planned measures Risk analysis – prediction of qualitative and quantitative state of water bodies, baseline scenarios (without measures), scenarios considering selected measurement options

9. Alerts Indicators Monitoring Networks & Databases Monitor Water & Environment Assess Predict Pollution Environmental Dispersion Risks USER Manage Water Resources Models & Tools USE CASES Determine Determine Optimize Wells Protection Zones Sustainable Yield Use cases overview Critical issues: • Interoperability of data sources & services (including e.g. alerts propagation!). • Documentation, including explicit semantic and quality assurance info. • Data transience vs. versioning. “UWECAT” semantic catalogue of data eases integration, annotation and versioning of data from variety of sources (standard office formats, DBs, shape files…)

10. WATERMARK – lessons learned • Interoperability: proprietary systems are bad for you, but you have to live with them for now => build modularly & use standards where possible. • (standardized) GIS everywhere: OGC-standards are a good start, but we need more; non-GIS data, models, services... • UWECAT can help: integration & maintenance of data from various sources; analysis and assessment of different scenarios; risk analysis, forecast and decision support; presentation and visualisation of results (e.g. 3D) • Use cases beyond WFD: making hydrology data usable to experts from other areas and to general public (e.g. traffic, tourism, regional planning, etc.) • Watermark architecture & web client: easy to deploy; easy to maintain; wizards are simple to use, e.g. by public administration.

11. A case for reusable components

12. Beyond WATERMARK • Research projects (FP6 IST): • ORCHESTRA IP: standardization of environmental risk management networks (services, protocols, semantic interoperability) • SANY IP: standardization of sensor networks; advanced data fusion and decision support services. Products (examples): • UWEDAT - versatile station computer & accompanying software suite • UWECAT – general purpose software for integrating, annotating & maintaining data.

15. WATERMARK - Challenges and benefits • Connectivity to existing systems • Support for complex problems and solutions for multi-sectoral integrationofplanning measures and strategies • Simulation, analysis and assessment of different scenarios • Information and communication management • Risk analysis, forecast and decision support • Integration of quantitative and qualitative monitoring data (interfaces to monitoring data logging) • Presentation and visualisation of results (e.g. 3D) • Tool for public participation • Living and scalable system -further development and adaptation online with experts and users

16. Grass and Modflow – Open Source Components for GIS-based Groundwater Modelling GRASS - GIS • Modular and scriptable Raster- & Vector GIS • Support of various (scientific) spatial analysis • Coupling with external modules (statistics, modelling) • Import and export of most GIS and image formats • Since 2005: r.gmtg – pre-processor for groundwater model MODFLOW • USGS ground water modelling tool • Different post-processing modules for modelling solute transport and chemical reactions (e.g. Modpath, MT3DMS) Base Data Base Data User Input Base Data Model Wrapper GRASS MODFLOW r.gmtg Output to Server

17. Example - Web-based simulation of a groundwater body • User – Map interaction to define area of interest and problem to solve • Location and problem specific input • Request sent to server for processing • Retrieval and pre-processing of additional data needed to answer request • Simulation engine and Model Wrapper feed the model(s) with data and store user specific information • Model computation • Run model with problem-specific input • Transfer result back to standard format • Result maps and information are sent back to client via standardized format and displayed in MapClient Data Retrieval Pre-processing Model Layer Post-processing
