The sea coast in Primorsko town in Bulgaria and specially the peninsula of the town was seriously damaged by costal geodynamic process—coastal abrasion in the zone covered by sedimentary rocks, landslides in the same sediments and rock falls in the volcanic rock zones. These processes seriously affected a number of the elements of the infrastructure of the town (roads, pipelines, power lines and a lot of private houses).All attempts to decrease individual hazardous processes in limited areas were unsuccessful because of the influence of the main factor of their activation—abrasion. This factor was the reasons for the landslides and rock falls. The fully solving the problem has been done during the period 2005–2007.Our team held engineering geological and hydro geological studies, which were used to compile the project for overall strengthening the sea coast. This project involved strengthening dams around the entire peninsula and was completed in 2007. Now all the processes of geodynamic are slacken and fortifying them is not a problem.
