The article examines recent Caspian Sea level change by using both satellite radar altimetry and satellite gravity data. The altimetry record for 2002–2015 shows a declining level at a rate that is approximately 20 times greater than the rate of global sea level rise. Seasonal fluctuations are also much larger than in the world oceans. With a clearly defined geographic region and dominant signal magnitude, variations in the sea level and associated mass changes provide an excellent way to compare various approaches for processing satellite gravity data.

This study is an attempt to develop an integrated methodology to predict the impact of the Caspian Sea on flooding using Geographic Information Systems (GIS) and hydrodynamic modeling. A rise in the sea level might lead to major flooding events, and have a severe impact on the spatial development of cities and regions. The feasibility of simulating a flood event along a drain channel is evaluated near residential development areas along the Chapakroud drain.

The study shows that at these elevations environmental and social problems arise with regards to the drain. The results also indicate that GIS is an effective tool for floodplain visualization and analysis. It should be noted that the mixture of salt and soft water, as a result of rising sea water level, is a problem that was not investigated in this study and should be examined in the future. 

This report analyzes oil and natural gas in the Caspian region, focusing primarily on the littoral (coastal) countries of the Caspian Sea (Russia, Azerbaijan, Kazakhstan, Turkmenistan and Iran). A discussion of Uzbekistan is also included. While not a Caspian coastal state, a considerable amount of Uzbekistan's territory, along with its energy resources, lies in the geological Caspian basins.

The combination of foreign investment and rising energy prices allowed the coastal countries to shift from diverting oil extraction for local use to supplying both regional and world oil markets. The ability of countries to export greater volumes of Caspian crude oil and natural gas will depend on how quickly domestic energy demand rises in those countries, how quickly they can build additional export infrastructure to global markets, and whether expensive projects to develop Caspian resources can attract sufficient investment.
