Web-based Information System for Transboundary Flood Management

In the recent years floods and accompanying landslides, have occurred quite frequently in Romania. Some of these have been isolated and others have affected large areas of Romania. One region, which suffers from floods on a regular basis, is the transboundary area of the Crisul Alb, Crisul Negru and Kőrős River. An important objective of the NATO SfP 978016 project entitled “Monitoring of extreme flood events in Romania and Hungary using Earth Observation data” is the development of a dedicated sub-system based on remote sensing and GIS technology (FLOODSAT), in order to improve the flood management and implementation of mitigation programmes, in these areas. The FLOODSAT sub-system is web-based with a distributed architecture and consists of a core server, that handles the interactions between the various modules, the end-users management, the display and manipulation of data. The GIS database is interconnected with the modelling modules and integrates the hydrological and hydraulic models into the sub-system. The main functions of the FLOODSAT system are the following: acquisition, storage, analysis, management and exchange of raster and vector graphic information and related attribute data for the flood monitoring activities, as well as updating the information, data restoring, elaboration of thematic documents and generation of value-added information. The distribution of the spatial and tabular attribute data over an Internet Web-based network represents a powerful and effective communication method that overcomes the disadvantages of the classical approach.
