Rivers and Water Systems as Weapons and Casualties of the Russia-Ukraine War

The geophysical, hydrological, and ecological consequences of the Russia-Ukraine war for the major rivers and water infrastructure in Ukraine are addressed here, focused on the dams and reservoirs of the Dnipro (Dnieper) River and major tributaries, up to and including the destruction of the Kakhovka Dam in June 2023, using remote sensing systems, on-the-ground reports, and official sources. The rivers have long played a role as physical barriers during conflicts, but in the current war, water and built water systems have also been targeted for attacks and used as both offensive and defensive weapons. Among the consequences of the conflict have been both direct and indirect effects on civilian populations, agriculture, military operations, water supplies and quality, and natural ecosystems. An historical review shows that such attacks have occurred in the past, but the extent and severity of the current violence appear unprecedented, raising important questions of international law and how international legal and scientific communities should respond.
