ON THE ROLE OF THE ABRASION SHORES AS THE SOURCE OF THE DRIFTING OF TERRIGENOUS MATERIAL IN THE SOUTH-EASTERN PART OF THE BALTIC SEA

All Northern coastline of the Sambian peninsula is the main supplier of the loose material for the eastern Baltic stream alluviation. The quantitative indices of the speed of the retreating of the coastline, the balance of the seaward entering of the terrigenous material, its differenciation and the formation of the longshore stream have been determined in this article. The general quantity of the washing out material is found to be 182933 m3/year between the Taran Cape and Zelenogradsk, from which aleurite pelitic particles as large as 99863 m3/year are washed out into the deep heights, whereas coarse fragmental material (15262 m3/year) is left on the shore. The power of the longshore sandstream at the root part of the Kurshiu Spit is 157808 m3/year.
