摘要
Simulations of the hydrological risks and thus the decisions of assessment strategies are crucial in the context of extreme meteorological events due to the consequences of the fast changes in the climate. The remote sensing methods, such as LIDAR backscatter technique are allowing the elaboration of a high precision (5cm vertical and 3 points/m(2) horizontal resolutions) Digital Terrain Model (DTM) as basis of the hydrological modeling. In this paper is presented the airborne LIDAR technique, methodology of obtaining the DTM, the usefulness of the DTM outputs for hydrologic applications and the potential application for the Romanian Danube Flood Plain assessment strategy.
