We examine the conflict situations in the international river and lake basins of Asia as engendered by the water factor. The situations are all separated into four varieties, such as the territorial-border, water-use, water-ecological, and natural-resource types. Furthermore, they are grouped together by their time of origin and manifestations as well as by the methods of overcoming them. We carried out their mapping. Examples of situations and of lines of attack on the problems are provided. Experience of cooperation of the countries on joint water management in the Asian basins is outlined. It is shown that the basin concept necessitates establishing uniform management rules for the catchment watershed as a system.Keywords: water crisis, international basin, Asia, conflict situation, typization, water use management.
