1 BRAHMATWINN Twinning European and South Asian River Basins to enhance capacity and implement adaptive management approaches 6th EU Framework Programme Priority: Global Change and Ecosystems Contract: No Project duration: – D EVELOPMENT OF A R IVER B ASIN I NFORMATION S YSTEM FOR A SUSTAINABLE DEVELOPMENT IN THE U PPER B RAHMAPUTRA R IVER B ASIN By Jörg Pechstädt, Franziska Zander, Hannes Müller Schmied, Anita Bartosch, Prof. Wolfgang-Albert Flügel Institute of Geography Department of Geoinformatics, Hydrology and Modelling Friedrich-Schiller-University Jena

2 BRAHMATWINN Upper Brahmaputra River Basin Data basis – historical information Projected data River Basin Information System Outlook Content

3 EC 6th Framework programme GLOBAL CHANGE AND ECOSYSTEMS Subpriority Twinning Basins Transfer of professional IWRM expertise, approaches and tools based on case studies carried in twinning European and Asian river basins, the Upper Danube and the Upper Brahmaputra River Basins. Enhance and improve capacity to carry out a harmonized integrated water resources management approach Twinning approach: Glacierfed basins Headwaters in alpine mountains Transboundary river basins GCC impact on water resources UDRBUBRB 76,653 km 2 533,000 km 2 Germany 73 % Austria 24 % Switzerland, Italy, Czech Republic 3 % China 55 % Bhutan 8 % India 37 % BRAHMATWINN - Project

4 Upper Brahmaputra River basin and the test sites

5 Slope AspectTopographic wetness index Geology Land use Spatial data

6 UBRB – Station distribution

7 Temperature trend between Station Shiquanhe (4280 m a.s.l.) UBRB – time series analysis – temperature trends

8 UBRB – time series analysis – temperature trends Temperature trend between Station Gauhati (54 m a.s.l.)

9 Increase in low areas Decrease in high area Precipitation shows no uniform trend: in some areas precipitation is decreasing, in some increasing Precipitation trend depends on the stations altitude Existing climates are already highly variable and climate change simply adds to the complexity and scale of the challenge of managing this variability. UBRB – time series analysis – precipitation trends

10 Since 1960 the glaciers in the Northwest-Himalaya have lost approx. 17 % of their area and up to 19 % of their volume. For an interval of 10 years these changes range between 5 % and 13 %. UBRB – glacier analysis – decade trends

11 Water level Brahmaputra at Dibrugarh (1953 – 2005) UBRB – impacts on runoff – Dibrugarh (India)

12 Discharge Lhasa River (1957–2003) UBRB – impacts on runoff – Lhasa (Tibet)

13 SRES scenarios can show the possible development of the natural environment – climate conditions and possible developments of the socio-economy Source: IPCC 2000 A1B rapid economic growth Population 9 billion in 2050 New and efficient technologies Extensive interactions A2 Heterogeneous World – self reliant nations Increase population (constant) Regional economic development Lower and fragmented technological changes B2 Divided but more ecologically world Increase of population (slower rate) Emphasis on local than global solutions to economic, social and environmental stability SRES – climate scenatios – further developments B1 Integrated, ecologically friendly Economic growth (rapid) into a information economy Population 9 billion in 2050 Reduction of material intensity technologies Introduce of clean and resource efficient technologies

14 GLOFs Summary for the actual situation UBRB – Lhasa River catchment – A1B scenario – temperatur and precipitation

15 GLOFs Summary for the actual situation UBRB – Simulated discharge till 2050 using CLM data (IPCC A1B)

16 Socioeconomic developments – example India – study of TERI (The Energy and Resources Institute) Projection of the gross domestic production (crore RS = rupees) Population Projections (millions) Projected Total Demand for Water (billion cubic meters) UBRB – Socioeconomic development - India

17 Historical Data Spatial Data Simulated Climate Information Simulated Socio-economic Information – water demand Ongoing Modeled future discharge, (hydrological parameter) WHAT-IF Scenarios – with IWRM options future Data Basis Data and simulation summary

18 Administration Metadata Management GIS Data DocumentsTimeseries River Basin Information System (RBIS)

19 RBIS - Functions

20 Define a period Green colour means that all gaps are filled red data have gaps Download for the time series Export for the period - Aggregation RBIS - Functions Quality information total number of entities View the data

21 RBIS – Frontend – data access via map

22 Frontend – Data access via Metadata (and search) RBIS – Frontend – data access via metadata and search function

23 RBIS: Database with the shown functions Access via internet Special access rights depending on data rights Historical climate data and hydrological data Spatial data (import is ongoing) Datasets: Simulation of SRES scenarios for A1B; B1 and A2 Actual vulnerability analysis Hydrological model results for the selected SRES Socio-economic projections for the sub basins RBIS – Actual status

24 Definition of scenarios in the RBIS – as object scenario – extent the database model Integration of the characterizing dataset to each scenario Development of the IWRM – options to the what-if scenarios Integration of the IWRM options into the RBIS – link them to the scenarios Import all needed datasets into the RBIS Build capacity to the stakeholder – to the local partner Installation the complete system to the partner site and the stakeholder site if wanted RBIS – Further developments – next steps - Outlook

25 Collection and sharing of data is the fundament of a successful IWRM – sustainable development This will be realized by the RBIS database, used for storage, administration and visualization of time series and geodata Reliable and accurate water resources information and data, by reducing uncertainty about water resources, help decisionmakers make more reliable and politically persuasive assessments of water risks (World Water Development Report 3). Summary The RBIS represents the central component of the IWRMS toolset - web-based database system - ISO standard
