IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

Predicting the Risk of Hydrogen Sulfide Zones Formation at the Amur River Transboundary Area
Author : Diana Andreeva and Liubov Kondrateva
The article explores the peculiarities of water quality formation at the Amur River transboundary area under the influence of sulfate reduction processes taking place within bottom sediments. Below the Songhua River mouth, the Amur water quality is affected by the flow of this right- bank tributary (Heilongjiang province) and municipal wastewaters discharged from the Chinese city of Fuyuan. To prediction the contamination of bottom waters with toxic hydrogen sulfide, we suggest using the coefficient of ecological risk of formation of local hydrogen sulfide zones. The coefficient is calculated by determining the quantitative relation between two bacteriobenthos groups (sulfate reducing\ammonifying bacteria). This coefficient makes it possible to determine the intensity of toxic H S 2 formation in the water-bottom contact area during water ecosystem eutrophication.
