In the last four decades, increasing of environmental and other risks due to climate change and sea level rise have been registered, leading to negative evolution of shoreline.
Black Sea relative sea-level is rising by an estimated rate of 1- 2 mm/year and many coastal areas are becoming susceptible to flooding. In addition to sea level rise, storm surge and waves are carried to higher levels on rising mean sea level and are also factors of the beach erosion.

The surveillance of the shoreline evolution based on GPS and remote sensing modern techniques (LIDAR), shows the need of the shoreline management, coastal protection and rehabilitation, especially for the vulnerable coastal areas against the threat of high waves and storm surges.
The integration of data is provided by a GIS system that improves their accessibility and their availability. GIS also provides efficient functions for rapid production of thematic or synthetic maps and other visualizations. GIS was used for the detection of spatial changes, for the assessment of future evolution, and for impact simulations.
