Instead of the assertion of national states, characteristic of the early 20th century, what we are witnessing now is the emergence of a denationalisation trend, the establishment of a system of global governance, capable to sustain and redefine the power of states, and of a global interdependent system very vulnerable to resources, technologies, as well as ethnicity, culture, religion, etc. The collapse of the communist political system and of the bipolar world order has created the premises of generalised economic, political-ideological or cultural globalizing connextions, a phenomenon associated with the proliferations of the increasingly more powerful transnational companies and supra-national organizations. This model will consider two basic elements: Through collaborative partnerships with local authorities, this demarche will be at the basis of improving general urban plans by means of a better administration of lands. That is why it is necessary to develop an assessment model of flood risk in the human settlements of Romania as a key element for assessing potential damage costs caused by flooding. The lack of a firm legislation at the beginning of the transition period determined a worsening of environmental conditions by uncontrolled deforestation, destructions of forest belts and irrigation systems and an accentuation of the impact of extreme hydrologic phenomena upon society.
Thus, the dykes and dams along the Danube and the main rivers have proven to be insufficient and in some cases inadequate in extreme situations propagation of flood waves being strongly influenced by these environmental changes.
Over the recent years Romania has faced a series of extreme events, among which the most important were floods and flash floods, most of them being caused by torrential rains, snowmelt or the two phenomena combined, amplified in many cases by the breaking of natural or artificial dams, dykes, etc. We have considered three perimeters of analysis: Şerbeşti-Săuceşti and Fundeni-Nămoloasa on Siret River, respectively Sadoveni-Ripiceni on Prut River. On the basis of this classification, we have carried out one representative case study regarding the floods from Moldavia in July 2010, using GIS mapping techniques. These led to the classification of Romanian cities in five classes of vulnerability to a certain genetic type of flood. Starting from the consequences of global climatic changes upon the local ecosystems we have tried to create a coherent methodology for assessing flood vulnerability in the cities of Romania based on a typical sample of indicators grouped in three sub-modules whose intensity was evaluated by grades from 0.1 to 1.
