Abstract
The article presents the results of a long-term study of hazardous environmental processes on the Sevastopol coast. Laser scanning allows estimating with high accuracy the natural and anthropogenic dynamics of Sevastopol coast that differ in the concentration of various exogenous processes in relatively small areas and pose a threat to the economic activities of the population. Using laser scanning (lidar shooting), key coastal sections were surveyed in the area of Nemetskaya gully and Uchkuevka beach, where landslide and abrasion processes are displaying. Ground laser survey was performed using a three-dimensional laser scanning system. It was carried out in July 2016, July 2017, July and October 2018. The study showed that the average rate of cliff destruction in the area of the Uchkuevka beach was 0.8 m/year. The maximum cliff destruction rate reached 4.6 m, which was observed in the local ten-meter section of the block slide. Because of terracing, an anthropogenic “cutout” about 150 m long, about 300 m wide and 2.5 to 10 m deep was formed in the area of the Nemetskaya gully. The calculation showed that the Vume of removed soil was 393,649.14 m3, and the Vume of dumped soil on the beach was 28,669.62 m3. The results can be used to monitor hazardous exogenous processes, model and predict coastal development, and make decisions for environmental management in the coastal zone.
