ABSTRACT
Currently, in the world, there are more than 40,000 dams that regulate the flow of rivers and affect the economic development of dry regions. Dams and weirs are built on 200 major rivers that cross state borders. Moreover, a third of these rivers do not have international treaties that would regulate water consumption from these rivers. In the following chapter we consider the emerging problems of countries neighbouring the basin of these rivers and have proposed ways to solve the emerging problems with the example of several transboundary rivers: the Tigris, the Euphrates, the Nile, the Jordan, the Zambezi, Kura and Chorokhi. The methodology for calculating environmental damage from wastewater disposal is presented as one of the proposals for international discussion. Using the example of some rivers in the South Caucasus, it is shown that an incorrect assessment of damage results may result in confront the neighbouring countries of transboundary rivers with environmental protections.
