DEYKALION: Assessment of flood flows in Greece under conditions of hydroclimatic variability: Development of physically-established conceptual-probabilistic framework and computational tools
The Project aims to develop a set of physically-based (by means of field observations) tools and methodologies associated with modelling and forecasting of extreme rainfall events and the subsequent flood events, which will be specifically adapted to the peculiarities of the hydroclimatic and geomorphological conditions of Greece. In this proposal, two leading consulting firms participate, i.e. ETME: Peppas & Co. Ltd (leader) and Grafeio Machaira SA, along with two major research institutes, i.e. the Department of Water Resources and Environmental Engineering of the National Technical University of Athens (NTUA) and the Institute of Environmental Research and Sustainable Development of the National Observatory of Athens (NOA).
The key idea is the development of a pilot river basin network, equipped with adequate gauging systems, so that it provides the necessary infrastructure for the systematic investigation of the overall components related to flood generation, including the spatio-temporal distribution of rainfall and the geometrical and physiographical properties of the river basin and drainage network. Based on systematic data analyses (hydrological, meteorological, geographical), we will develop physically-established regional models for the estimation of characteristic hydrological design magnitudes, as well as general purpose hydrological-hydraulic models that will be used for formulating improved design principles for flood-protection works and the estimation of the associated risk. The above mathematical tools, coupled with meteorological models for short-term storm predictionare integrated within an information system, to be applied for flood prediction in the selected pilot basins. The total budget is at 576.000 EURO.
