“Impact of Caspian Sea level fluctuations on the landscape ecology condition of the Lankaran-Astara coastal zone” scientific-research.

Within the framework of the scientific research, the archival materials of the area, the soil-vegetation cover and landscape complexes of the coastal zones were studied. In addition, the Caspian Sea and its level fluctuations, wind regime and currents were studied. On the basis of 70 years of observational data, level fluctuations were analyzed and statistical analyzes were carried out, including graphical design works. Experimentally, topographic and bathymetric surveys were performed in the coastal zones of Lankaran region based on modern approaches to investigate the landscape-ecological situation. A triangulation network model of the research area was created and comparative analysis of the obtained results with archival satellite data was carried out.

 The issues raised and solved in the scientific research:

• Studying archival materials on the research area, using literature sources (references);
• Studying the characteristics of soil-vegetation and landscape complexes of coastal zones covering Lankaran and Astara regions;
• Studying the condition of natural resources of the Lankaran-Astara coast of the Caspian Sea and their use;
• Studying the impact of economic activity on the environmental components of Lankaran-Astara coasts;
• Studying of the Caspian Sea and its level fluctuations, as well as the wind regime and currents (geological and historical, modern fluctuations and their causes, the study of the impact of the level increase on the socio-ecological conditions of the region, the study of the impact of new fluctuations on the modern dynamics of Lankaran-Astara coasts);
• Conducting statistical analyzes based on observational data;
• Analysis of Caspian Sea level fluctuations based on 70 years of observational data;
• Study of the causes of sea level increases and decreases;
• Studying of seasonal level fluctuations;
• Classification of prevailing winds and their indicators, duration and directions, as well as study of their distribution in directions, study of repetition of maximum windy days;
• Conducting topographical surveys experimentally in the coastal zones of Lankaran region and performing bathymetric surveys with hydrographic echo sounder, studying the landscape-ecological condition with modern methods;
• Bringing the surveys results to the elevation system for the purpose of determining the current state of level fluctuations, balancing issues;
• Preparation of relief profiles based on the triangulation network model;
• Digital mapping of the distribution of average annual precipitation anomalies of the Caspian coastal areas based on vectorization based on GIS.
