Presentation Transcript

  1. Partner 68Center for Environmental Systems ResearchUniversity of Kassel

  2. physiographic data Water Availability per 0.5° grid-cell Water Stress -per basin- climate data Water Withdrawals per sector per country/grid-cell socio-economic data WaterGAP-overview- Hydrology model Water use model

  3. ActualEvapotranspiration - Rain & Snowmelt + RIVER DISCHARGE - Surface Runoff &Groundwater Recharge -Hydrology Model- SOIL WATER BALANCE

  4. What we have done: • Task 6.2.1 Preparation of the model WaterGAP (completed) • Task 6.2.4 Definition of critical impact thresholds (completed) • Task 6.2.3/ Task 6.2.8 preliminary sensitivity analysis and response surfaces (completed)

  5. Sensitivity analysis and response surfaces for 18 case study river basins

  6. Response of water availability to climate variations

  7. Guadalquivir (Southern Europe) Danube (Central Europe) Lule (Northern Europe) In their response, the river basins can be divided into the three groups: northern, central, and southern European basins Fig.: RS for northern, central, southern European catchments

  8. What we plan to do: • M6.6 Sensitivity analysis and response surfaces based on ENSEMBLES climate data • Use the threshold theory to identify crucial conditions of water resources Points of discussion • When will ENSEMBLES climate projections become available (and when will our results be required) • River basins (selection of case study river basins) • Timeframe of underlying climate data ( depends on scenario time frame – currently 1961-1990) • Format of response surface  use uniform format
