摘　　要：The War of the Triple Alliance was an international military conflict in South America, fought from 1864 to 1870 between Paraguay and the Triple Alliance of Argentina, Brazil, and Uruguay. In 1939, according to the provisions of the Arb6-Cantilo Treaty, it was established that the international boundary between Argentina and Paraguay passed through the deepest channel of the Pilcomayo River. The natural complexity of the river, plus the condition of acting as international border, led to perform this analysis. The main goal was to implement geo-processing techniques to map the evolution in the drainage pattern, linked to natural processes or human activities from 1951 to today. Satellite imagery and historical maps were integrated upon a Geographic Information System （GIS）; to interpret the changes occurred in the last 60 years along the Pilcomayo River channel which is approximately 20,000 km^2 located in Argentina and Paraguay. The collected information allowed the authors to evaluate and demonstrate the degree of correspondence between the river variation and the topographic position of the international boundary between Argentina and Paraguay, and also to diagnose what could occur in the near future.
