adopted to resolve conflicts of interest in the management of water resources in trans-border river basins. Water conflicts often enough results from opposing interests of water users. This is especially true in trans-border river basins where the freshwater river travels across more than one country. Conflicts among water users arise as water quality or water quantity degrades and no longer meets the demands of each country. Today we will be discussing on some examples of trans-border river basins
