Rio Uruguai: contribuições científicas

Abstract

The Uruguay River has its origin in the confluence of the rivers Pelotas and Canoas, border between the States of Rio Grande do Sul and Santa Catarina. Considering the international geopolitics, it crosses extensive area making currency between the territories of Brazil and Argentina. In the middle Uruguay region, where the Uruguaiana Municipality is located, further south, after it receives its tributary Quaraí River, the Uruguay River divides the Argentine and Uruguayan countries. It ends its southern journey on the River Plate, which flows into the Atlantic Ocean. However, the Uruguay River examines the settlement of its extensions about 10,000 years BC, that is, its history, contextualized from its earliest inhabitants, prefigures the development of approximately 600 human generations. From remote times, the Uruguay River was understood as an important ally of subsistence, since the climate that the first immigrants encountered shortly after the last glaciation was cooler and drier, with icy winds and little vegetation. This scenario, paradoxically, coincided with the Uruguay River so that these peoples could find their subsistence close to their banks (SHIMITZ, 2006). In this way, the work seeks to bring the scientific contributions around the Uruguay River.
