Abstract

An aim of the research is to investigate an impact of the Caspian Sea level fluctuations on the ground water regime and functioning of the hydro-meliorative network on the Caspian side zone, including Mugan- Salyan region. On the basis of the long-term data of Baku meteorological station during 1830-2014, the water level changes in the Caspian Sea was analyzed, calculations on ground water level fluctuations on the sea influence zone with the application of the selected calculation method were performed. It was determined that due to the changes in the Caspian Sea level between-28,9 m (minimum) and -26,13 m (maximum) interval, the ground water tables at the 25 km influence coastal zone, changes between 0,5- 1,93 m. These values are less than an accepted for the zone value of hesk=2,2 m. An analysis of the data shows that due to the fluctuations, especially rising of the Caspian sea water level, the normal working regime of the hydro-reclamation network (collector and drainage system, different type of the irrigation canals and rivers) under operation have been disturbed in the side zones, including in Mugan-Salyan massive. Consequently, this creates risks for formation of secondary salinization, water logging and desertification in the Caspian Sea influence zone.
