  1. Climate induced changes on hydrology and water resources managing river basins in southern and Eastern Europe A.Unal Sorman METU, Faculty of Engineering Water Resources Division Ankara- Turkey

  2. Objectives Changes in water resources (time/area) of the Eastern and Mediterranean countries of Europe should be observed in short and medium time domain where water gets scared (unpredictable) due to change of climate and/or misuse of water sources by human interferences which effect inversly on water resources within the region.

  3. Integrated basin management In order to achive the stated objectives , the river basins located in this region should be managed in an integrated manner among the nations as well within nations by observing the meteorological and hydrological parameters in time and space domain in the region sharing them and analyzing the processed information with recent scientific techniques.

  4. Climate change It is expected to effect significantly on input and output elements in near future of the water budget of watersheds as a result of expected extreme events on rainfall amount may increse or decrease resulting draught and flood conditions in the area, finally creating some infrastructural damages, loss of life for high flows and agricutural drought by lowering groudwater table as a result of less runoff .

  5. Side effects due to areal coverages This situation will also create additional side effects for the vulnerable areas at upper part of the basins (hillslope) which are mountainous ( bare or forest/vegatation cover) to get less or more snow coverages.

  6. Snowmelt Due to rasing of air temperature in early months of spring season (Feb and march), snow is expected to melt earlier which needs to be controled to minimize the flooding risk and as well the amount of snowmelt should be predicted to maximize the reservoir operation systems to generate more hydropower energy with limited runoff storage, to supply drinking water effectively and to provide water for irrigable lands when it is needed in summer months.

  7. Solutions by satellite tech’s Considering all these factors, research is needed in coloborated way among the participating countries to combine the data stored information and effort in near real time base using also satellite techniques to analyze exisiting and predicted resources within the Mediterranean and eastern countries (share the information).

  11. Validation of SN-OBS1b For the first 3 months period of 2008 over: • Turkey • Slovakia Ankara-Turkey

  12. Turkey Comparisons made for 78 climatic stations where 1736 measurements have been used. 3 months POD = 99 % FAR = 9 % Ankara-Turkey

  13. Slovakia Comparisons made for 72 climatic stations where 1954 measurements have been used. 3 months POD = 69.7 % FAR = 31 % Ankara-Turkey
