Short history Due to the last years floods (spring 2006)

Environmental Ministry and Sustainable

Development from Romania decided to launch

a study which will lead to reestablish the line

defenses of the localities (the new ones), so that

the next major floods do not put in danger

humans life. The solution=A Digital Mapof the Danube River

and Danube Delta

Conclusion Airborne LIDAR mapping is the a quick

and very precise way to produce high-

resolution digital elevation data for floodrisk management. This LIDAR data set

allows planners and hydrologists to predict

flood extends and plan remedialstrategies.
