- Article - Long-term and seasonal Caspian Sea level change from satellite gravity and altimeter measurementsMon, 16/07/2018 - 15:43The 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.

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.

- Description
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.

- Description
This brochure has been produced on behalf of the consortium developing the hydrocarbon deposits beneath the North East Caspian defined under the North Caspian Sea Production Sharing Agreement of 1997.
The concession area lies in a region of rich biodiversity recognized as being of international importance for its wildlife, including several species that are classified as endangered. The widely varying conditions in the North East Caspian include extreme seasonal temperature variations, long-term sea level change, short-term sea surges and retreats, high levels of turbidity and sediment movement, ice cover in winter and scouring of the seabed by moving ice.
This dynamic environment presents challenges for those who live and work in the area. It also means that the fauna and flora on land and at sea, are adapted to a significant level of environmental stress from continually changing physical conditions.
