How to read this map
The Uruguay River is about 1,790 km (1,110 mi) long and drains a basin of about 365,000 km² (141,000 sq mi). Its average discharge is about 5 m³/s (163 cu ft/s). It rises at the Pelotas River and flows into Río de la Plata. It flows through or along Uruguay, Brazil and Argentina. Tributaries include Río Negro, Arroyo Boycuá, Arroyo Chapicuy Grande, Arroyo Negro, Arroyo Román Grande, Arroyo Yacuy, Arroyo de la Agraciada and San Salvador River.
The highlighted blue line is the course of the Uruguay River as mapped by Natural Earth. Towns and cities on the map include Porto Alegre, Rosario, Florianópolis, Joinville, Novo Hamburgo, Santa Fe, Resistencia and Caxias do Sul. Labeled countries: Uruguay.
Greens show lower elevations; tan and brown show higher land, with pale tones toward the highest terrain. Shadows emphasize the slopes, and vertical relief is exaggerated so landforms are easier to read. Dashed lines show country borders.
The relief uses Terrain Tiles (SRTM, GMTED2010 and ETOPO1 elevation data). Rivers, lakes, borders and the course of the Uruguay River come from Natural Earth, and the figures on this page from Wikidata. Natural Earth draws features at a small scale, so the line is a guide to where the Uruguay River is, not a surveyed boundary.
