Аннотация:In the article the main stages and impact of Caspian Sea level fluctuations on the north-eastern
coastal landscapes (coastal area in Atyrau and Mangistau regions of Kazakhstan ) for the period of
1978 to 2014 are considered. Land cover changes and distribution of negative geo-ecological
processes (salinity, flooding) were identified based on the use of Landsat 1977, 1987, 1998, 2013
multispectral satellite images. Normalized Difference Water Index (NDWI) was calculated to
identify the water table. On the basis of the values of brightness characteristics and synthesis of
Landsat satellite images channels the article explains the correlation between vegetation and coast
moisture conditions during transgressive phases and emergence of saline areas in the receding
coastline. The author’s research objective was to evaluate the degree of sea level fluctuations
impact (high, moderate, low) on different types of observed landscapes which have been exposed
to marine transgressions in different geological epochs. As a result, the main conclusion was made
that the intensity of the impact of sea level fluctuations on coastal landscapes to a large extent
depends on the terrain, formed during long transgressive phases (1977 - 1995 years, the earliestand late Caspian transgressions) which also connected with groundwater depth level, wind-driven
waves zone of impact and the main characteristics of land cover. The author emphasizes that the
study of modern areas affected by flooding will help to determine «risk flood zone» and to define
danger levels of areas for a different economic activities development.
