WEB-BASED GEO-INFORMATION SYSTEM FOR TRANSBOUNDARY FLOOD MANAGEMENT

V. Crăciunescu, G. Stăncălie, Ş. Constantinescu, I. Ovejanu

ABSTRACT
In the latest years floods and accompanying landslides, occurred quit frequently in
Romania, some of which isolated, others-affecting wide areas of the country's
territory. One region, which suffers from flood damages on a regular basis, is the
transboundary area of the Crisul Alb, Crisul Negru and Koros River. An important
objective of the NATO SfP 978016 project “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
programs, in the mentioned area. The FLOODSAT sub-system is web-based with a
distributed architecture and consists in a core server, which handles the interactions
between the various modules, the end-users management, the display and manipulation
of data. The GIS database interconnected with the modeling modules, integrates the
hydrological and hydraulical models into the sub-system. The main functions of the
FLOODSAT 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.
