8. WBalMo Elbe – model development: modular structure
22 modules: central module is Elbeschlauch (Elbe main river)
each module can be used stand-alone

9. WBalMo Elbe – model development: water yield
is an input from precipitation-runoff-model SWIM: for each simulation sub catchment at its end profile
can be an output from WBalMo: at each balance profile at each step of balancing process

Change of water withdrawel from period 1 to 10 (median, relating to the wetland area)

37. Conclusions and outlook
Water use conflicts exist both for extreme drought situations and for climate change
Water shortages from withdrawals occur in tributaries to Elbe river
In the main Elbe river water use conflict is due to minimum discharges for different purposes
Outlook
For all water users vulnerability for extreme drought situations, for climate and socioeconomic changes will be analyzed,
For reservoirs and dams failure in water supply will be analyzed,
For most affected water uses water management options will be developed
