Abstract:
Before presenting in detail the theme that this paper deals with, it is necessary to integrate the research on this matter within the larger context of global change, which is at this time in a stage of unprecedented evolution. In the last decades, the number of meteorological and hydrological disasters has gradually grown worldwide, thus affecting hundreds of million people every year. As a consequence, it is absolutely necessary to understand the vulnerability and the sensibility of the human community on medium and long term to hydro meteorological risks and the stringency for interdisciplinary studies related to flooding. Therefore, the experts in this field are faced with the assignment of developing disaster risk management strategies. Floods represent the most frequent disaster that can occur on various scales, ranging from large to small rivers, with impact on the state of the environment, including not only economic loss and ecological imbalance, but also claiming numerous human lives. As Geographic Information Systems (GIS) and spatial database technology are forthcoming tools for the tight circles of experts, working in the fields of geodesy and geography, managing areas prone to floods by means of this technology represents the optimal solution. Moreover, disasters, regardless of their type (natural or anthropic) will continue to appear, this leading to the need for different users in the disaster management sector to share and access the information.
