The disastrous flood events of the past ten years have caused numerous human casualties in the CADSES region. In addition the material damage reached unprecedented levels. Inspired by the successful Dutch/German flood information project, NOAH, Slovakia, Hungary, Germany, Ukraine and Romania have taken the initiative and pooled their efforts to reduce the effects of flood events in their territories. The main target of the MOSES project is to contribute to the development, implementation and management of a unified computer-based flood protection system for the entire region. In Ukraine and Romania there is primarily a need for upgrading their hydrological measurement stations. Slovakia's main interest is to select an information system which is compatible to the Hungarian Flood Management Information System (FMIS). Hungary focuses on flood hazard mapping and, as a lowland, benefits from an adequate flood information system in the entire region. Expected Results: The overall, long-term objective of the project is the reduction of flood damage and an increase in the efficiency of flood management by improving decision-making and tools for local, regional and transnational co-operation at river basin scale. The focus lies on implementation and management, including further development and adjustment to the local situation of a unified GIS-based digital flood information system in the region capable of managing online hydro-meteorological and hydrological data by selected forecasting and scenario analysis models. A further target is the dissemination of reliable flood information data on two levels: expert and system information layers for organisations that are in charge of emergency operations and management activities and to the public, professionals, organisations and the media. The main output of the project will be a digital flood information system for Slovakia and the German Free State of Saxony. The system should be compatible with systems that are used in adjacent countries. Moreover, guidelines for a methodology for GIS-based flood hazard mapping will be developed and a system for informing the public and international organisations about relevant flood data will be designed and implemented.
