Abstract
<p>The paperwork is part of a substantiation study about the current state of the NW Black Sea coastal area and it consists in the establishment of a reference database regarding hydrotechnical structures, the existing coastal protections, their impact and the identification of risk areas. A high-risk area is “2 Mai - Vama Veche” region, located in The Southern Romanian Coastline, due to the sharp beach erosion and the cliffs instability that endanger nearby buildings. The coastal protections, the offshore breakwaters, the industry development in the coastal region and the construction of storage lakes and dams in the river basins have influenced the conditions in which The Romanian Coast is found nowadays.</p>
Highlights
In this paper, a practical method is presented to assess the risk of erosion of beaches and seafronts through the analysis of the main factors responsible for the erosion
Measurements on waves and marine currents have been made at the Oceanographic Measuring Station of INCMD, equipped with underwater probes ADCP (Acoustic Doppler Current Profiler) for measurement of marine currents, wave parameters and automatic stations equipped with sensors to measure the variations in water level
There are a number of human activities that have influenced the Romanian coast, such as coastal protection measures, protective breakwaters harbor, development of industrial capacities in the coastal zone, the introduction in ecosystem of not indigenous species, and the construction of reservoirs and dams in the river basin
Summary
A practical method is presented to assess the risk of erosion of beaches and seafronts through the analysis of the main factors responsible for the erosion To this end, 10 physical variables are integrated (such as the lithology of seafronts, features of the seafronts, waves, currents, precipitation regime etc.) and 6 socioeconomic variables (such as the type of land use and population density). 10 physical variables are integrated (such as the lithology of seafronts, features of the seafronts, waves, currents, precipitation regime etc.) and 6 socioeconomic variables (such as the type of land use and population density) These variables are weighted and combined into a Hazard Index and an Impact Index, resulting in a Risk Index. An efficient strategy for integrated management of the coastal zone can be established after the correct assessment of the risk of erosion of the coastal zone, hazard and impact factors (vulnerability) of the area
