Brazilian watersheds have a high species and natural resources biodiversity. To know the features of scientific production on these regions is important to adjust study focus and to determine publication biases. This study aims at characterizing the scientific literature about Brazilian watersheds on scientometric grounds. For this purpose, we performed a search of articles in the ISI Web of Science database of the Institute for Scientific Information (ISI). The search returned 2,945 articles: 1,613 on the Amazon basin, 584 on the La Plata basin, 262 on the São Francisco basin, 190 on the Tocantins basin, 117 on the Southeast Coastal basin, 70 on the Eastern Northeast Coastal basin, 48 on the Parnaíba basin, 45 on the South Coastal basin, 14 on the North Coastal basin and two on the Western Northeast Coastal basin. The highest number of articles, journal diversity and impact factor was for the Amazon basin. Generally, the increase of the number of articles on the coastal basins over the years is lower. A keyword analysis shows that the study of most basins deals with similar subjects. However, researches on the Amazon and La Plata basins follow lines that are very different both from each other and from the other basins. In view of such results, incentives for new studies must focus on coastal basins. It is also recommended to submit works to good quality journals.
