  1. 4th MEETING SADMOSEVILLE, SPAIN, FEBRUARY 2008 WATER RESOURCES INDICATORS AND STATISTICAL ANALYSIS OF THE HYDROLOGICAL DATA EAST OFGUADIANA RIVER AT REGIONAL SCALE HYDROLOGIC ANALYSIS AND MODELING OF RGG WATER RESOURCES AT REGIONAL AND TEMPORAL SCALES P. ANGELIDIS AND N. KOTSOVINOS DEPARTMENT OF CIVIL ENGINEERING DEMOCRITUS UNIVERSITY OF THRACE 67100 XANTHI, GREECE

  2. DUTH RESEARCH OBJECTIVES • REGIONAL STATISTICAL – HYDROLOGIC ANALYSIS OF THE PRECIPITATION DATA • WATER RESOURCES INDICATORS AT REGIONAL SCALES AND VARIOUS TIME SCALES • TEST FOR THE APPROPRIATE PROBABILITY DENSITY DISTRIBUTION TO DERIVE THE STANDARDIZED PRECIPITATION INDEX (SPI) AT REGIONAL SCALE FOR VARIOUS TIME SCALES; KOLMOGOROV-SMIRNOV GOODNESS-OF-FIT TEST

  3. STANDARDIZED PRECIPITATION INDEX (SPI) FOR VARIOUS TIME SCALES AT MANY STATIONS COVERING THE REGION UNDER STUDY, USING THREE DIFFERENT PROBABILITY DENSITY DISTRIBUTIONS • TREND LINE OF SPI • REGIONAL STATISTICAL ANALYSIS OF TEMPERATURE AND EVAPORATION • ADDITIONAL DROUGHT INDICATORS COMBINING HYDROLOGIC, EVAPOTRANSPIRATION AND VEGETATION DATA

  4. Meteorological stations in the area under study (Guadiana)

  5. WE MADETWODIFFERENT STATISTICAL ANALYSIES FOR COMPUTATION OF THESTANDARDIZED PRECIPITATION INDEX (SPI) FOR VARIOUS TIME SCALES AT MANY STATIONS COVERING THE REGION UNDER STUDY: • The precipitation timeseries completed after correlation, but not extended. So timeseries of variant meteorologic stations have not the same time period • The precipitation timeseries completed after correlation, and extended to have all the same chronicle basis 1931 - 2007 THE RESULTS ARE QUITE DIFFERENT AS WE WILL SEE NEXT.

  6. TESTING THREE THEORETICAL CUMULATIVE PROBABILITY DISTRIBUTIONS FOR MONTHLY PRECIPITATIONTheoretical distributions seems to fit better to the larger timeseries (right figure)
