PRELIMINARY RESULTS REGARDING BEACH BEHAVIOR IN THE CONTEXT OF COASTAL PROTECTION WORKS IN THE CONSTANTA-MAMAIA SECTOR

In order to minimize coastal erosion, increase the value of the coastal zone and create new beach areas for tourism, a Master Plan was developed to protect the coast, that includes measures to reduce wave energy (height) that reach on the shore, the silting of the beach with dams for sand stability (spurs) and measures to retain sand on the beach (by building new dams, repairing the existing "breaking wave" dikes and construction of dikes perpendicular to the shore). The Master Plan provides the strategic vision of Romanian Black Sea management, providing a prioritized, sustainable, long-term approach, oriented to manage and combat erosion consequences and implications on the environment, marine ecosystems, economic and social values of the coastal area. An important component is the local strategic monitoring for collection of data and information on coastal work performance. The surveillance of the shore evolution started since 1980, currently the measurements are based on GPS and remote sensing modern techniques (LIDAR), beach profiles and granulommetry. This paper analyzes the preliminary results of beach behavior in context of starting in 2013-2014 the coastal protection works. 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, detection of spatial changes, for the assessment of future evolution, and for impact simulations.
