Introduction

The Río de la Plata is the second largest river estuary in South America, formed where the Paraná and Uruguay rivers meet on the border of Argentina and Uruguay before flowing into the Atlantic Ocean. Its mouth spans about 220 kilometers, making it the widest estuary in the world. Montevideo lies on the northern Uruguayan shore and Buenos Aires on the southern Argentine shore, linked by regular ferry and fast craft services. The water carries heavy suspended sediment that gives it a distinctive yellowish-brown color, locally nicknamed \"Mar de Dulce\" or sweet sea. The estuary hosts historic ports, beach resorts, wetlands and waterfront promenades, serving as the core waterway for shipping, fishing, ecology and urban leisure in southeastern South America and bearing the historical and economic ties between the two nations.
