- Abstract
An analysis of changes in the coastline of the Nemunas River delta front was undertaken with GIS based on cartographic material representing a 95 year period. Delta development was analysed comparing two time periods: 1910-1958 and 1958-2005. Quantitative indicators of land area determined during the study indicate that land in the northern part of the Nemunas delta front decreased more than 2.1 times in the 1958-2005 period, compared to the previous 1910-1958 period. The main reasons for the decrease of sediment accumula- tion are a decrease Nemunas River runoff, and a similar decrease of sediment particulates, due to anthropogenic activity and natural factors a rise in the water levels of the Baltic Sea and the Curonian Lagoon, as well as land subsidence in the Nemunas delta region.
