Daniil, Flood study, Engineering consultant for the project "Water supply of Heracleio and Agios Nicolaos from the Aposelemis dam", Commissioner: Ministry of Environment, Planning and Public Works, Contractor: Aposelemis Joint Venture, Athens, October 2001.
The objective of the study is the estimation of the design floods of the spillway and the diversion tunnel of the Aposelemis dam. The study is based mainly on regional rainfall and meteorological data. Initially, the data is analysed applying probabilistic techniques as well as the probable maximum precipitation concept, in order to estimate the characteristics of design storms. Next, a unit hydrograph of the catchment is synthesised and using this unit hydrograph and the design storms, the design floods at the dam site are estimated for various return periods. Finally, these floods are routed through the spillway in order to estimate the characteristics of the outflow hydrograph.
