Natural Evolution of Western Shore of a Sambian Peninsula on Completion of Dumping from an Amber Mining Plant

This article shows how dumping of sediments from an amber mining plant prevented erosion of the western shore of the Sambian Peninsula (in Kaliningrad Oblast). The average annual dynamics of coastal areas in the vicinity of the former dumping site of the amber mining plant is described. Nowadays the erosion is continuing after cessation of dumping. The rate of erosion was estimated by results of regular monitoring measurements, using airborne laser scanning. It was found that about 250000 cubic metres per year of local material is needed every year to prevent further erosion and retreat of the shore.
