Aspects regarding the lay-out of the flood strips and the elaboration of hazard maps following the subsidence of hydrotechnical works

Abstract

Current climate change, materialized bythe increase in the number of extreme rainfall phenomena, combined with increasing anthropogenic activity (massive deforestation), causes the flood process to appear more and more often and with increasing impact on the human component and its habitat, causing hydrological accidents. . These accidents are called hydrological hazards. Hydrological hazards are natural phenomena, which imply the existence of water, which have a direct negative influence on people's lives, on society and on the environment as a whole. The results of the flood study can be better used if integrated into a GIS model. By over lay technique, all data of interest can be stored, with specific representations of levels, speeds, times, and other elements of the evolution of the phenomenon.
