ABSTRACT
This paper describes the use of video sensor camera, in order to achieve a hazard map in GIS format on sections with flood risk of the watercourse of the Bistrita River. The project’s purpose to achieve the flood hazard maps in GIS format will provide decision makers the possibility of using the local risk maps by simulating possible situations such as flooded area expansion depending on water velocity, depth of flood corresponding flow rates with different probabilities of exceeding them, and also damage assessment and population evacuation plans taking into account the configuration of the terrain and the locations that can be used in these exceptional circumstances. In order to obtain the results we collected images with the Hirrus UAV build by Team Net Company. After analyzing the data, the next step was obtaining the digital model of the watercourse and the adjacent area. Besides aerial survey we used measurements made in the field with a GPS on the flight route marked previously. These data formed the basis for editing maps in GIS format. The main purpose is effective territorial organization for the operations in case of floods. The first reactions to the establishment of the state of emergency are important to reduce damage. Of course, a good plan of action in place, involving low cost with maximum results is needed. Such flood prevention map serves these goals. Simulation of possible situations will help create rapid intervention schemes adapted ground phenomena.

Keywords: Flood, Bistrita River, UAV Hirrus, prevention, damages.
