Use of S/S ratios for evaluating anthropogenic impacts on Volga-Akhtuba flood plain surface waters

چکیده
The sulphur isotope content, ôS, of sulphate from two potential pollution sources in Volga-Akhtuba flood plain surface waters was investigated. Isotope compositions of sulphur compound emissions from the Astrakhan Gas Condensate Complex and the Astrakhan Pulp and Paper Mill were significantly different which provided an opportunity to differentiate effects from these two emission sources on nearby natural waters. The method of isotopic identification of sulphur pollution sources was developed. The contribution of anthropogenic sulphur to nearby natural waters of the Volga-Akhtuba flood plain was estimated.

A computer simulation of the Volga River hydrological regime: a problem of water-retaining dam optimal location
We investigate of a special dam optimal location at the Volga river in area of the Akhtuba left sleeve beginning (7 km to the south of the Volga Hydroelectric Power Station dam). We claim that a new water-retaining dam can resolve the key problem of the VolgaAkhtuba floodplain related to insufficient water amount during the spring flooding due to the overregulation of the Lower Volga. By using ...
متن کاملA Simple Harmonic Model for FAPAR Temporal Dynamics in the Wetlands of the Volga-Akhtuba Floodplain
The paper reports a technique used to construct a reference time series for the fraction of absorbed photosynthetically-active radiation (FAPAR) based on remotely-sensed data in the largest Russian arid wetland territory. For the arid Volga-Akhtuba wetlands, FAPAR appears to be an informative spectral index for estimating plant cover health and its seasonal and annual dynamics. Since FAPAR algo...

متن کاملInvestigation of Surface Penetration of Flood Deposits in Geomorphologic Units North Urmia Lake
The study area is located north of Urmia lake and Tasuj plain. The average height of 1700m and average rainfall in the area about 363mm. The average annual temperature 10/65°C. Investigations on the surface penetration of flood deposits are important for the implementation of artificial recharge aquifers. In this study, soil permeability changes from Plain to lake were measured using double c...
