Based on the analysis performed in the Kura geomorphological sub-region of the Caspian coastal zone, it was determined that the sea level rise of 2.43 m in 1976-1996 caused an average annual rate of erosion processes about 75 times higher than accumulation processes. In 1996-2019, the stabilization and the following drop of the sea level of 1.39 m led to an average annual rate of accumulation processes up to 14 times higher than the average annual rate of erosion processes. This pattern is observed along the entire coastline of those periods. Erosion processes in the initial stage (1976-1996) increased the indentation and length of the coastline by almost 2 times, and in the next stage (1996-2019) the intensification of accumulation processes resulted in the smoothing and reduction of the coastline by 35 %. Statistical analysis of coastlines was carried out by processing Landsat satellite images for 1976-2019; each coastline was divided into 14 segments according to geomorphological zones and their morphostructures in the study area. The development forecast for the next 10 and 20 years is provided., Jeyhun Yashar oglu Gasimov., and Obsahuje bibliografii
Solar activity has important effect on terrestrial environment in which human population lives. Long-term and short-term periodicities in solar activity had influence on secular climate changes, little ice ages and climatic optima. The article summarizes briefly the results and methods of historical climatology. The text resumes the methods of research of the solar activity variation over the last 1500 years, through physical methods as well as through preserved written sources. The basic mechanisms of the effects of solar activity on terrestrial environment and human population are explained as well as the predictions of the upcoming solar activity. This may indicate that we are currently at the beginning of another long-term solar minimum., Kateřina Podolská., and Obsahuje bibliografii
