Hydrological characteristics of the Sperchios basin

The hydrologic characteristics of the Sperchios River basin are presented and analysed. To this aim all hydrologic measurements of the Sperchios basin, starting at 1949, as well as measurements at neighbouring hydrologic basins have been collected and compiled. Special emphasis has been given to the discharge measurements at the locations Kastri Bridge and Kompotades Bridge, which had remained unprocessed until today. From the records formed, the surface water potential of the Sperchios basin was estimated, which proves to be one of the most important in the water district of the Eastern Sterea Hellas. Furthermore, a trend analysis for the rainfall and runoff series is presented, which indicates the existence of falling trends in both series. Finally forecasts of the flood discharge at various locations along the Sperchios River for different return periods are given.
