Rezumat:

Airborne LIDAR technique by its specifications and characteristics in terms of precision of the
numerical terrain model and the use of the GIS technique can be used in geomorphology. REELD
campaign (elaboration of a precise numerical model of the terrain over the whole Romanian Danube Plain
with more than 600,000 ha distributed along 1,000 km and variable widths from 1 to 80 km large were
scan from 600 m altitude) represented an opportunity for the analyse of actual geomorphology processes.
After a brief introduction about airborne LIDAR technique and a short description of parameters and
methodology used in the field campaign, this paper consider the application of the airborne LIDAR
technique to the provision of elevation data at accuracies and spatial densities suitable to use with the
current generation of high-resolution hydraulic models. Finally, the scientific challenges to describe
geomorphologic processes and map the soil loss, due to erosion, using the combination of airborne
LIDAR data and GIS technology for a rapid production of cartographic representations of floodplain
environments is particularly pointed out.
