The aim of this project is to image, digitize and quality control historical Paraná-Uruguay River hydrometric data that go back as far as 1875. The main focus of this project is on water level data from gauges located in the lower stretches of the Paraná-Uruguay River system (southeastern South America). Since these gauges drain large basins (365,000 to 2,500,000 square km), their water level data provide valuable information on hydroclimate variability at sub-continental scales. Historical rating curves are obtained and used to convert historical water levels into river discharges.

We are also rescuing pre-1950 meteorological data that were found in some ports of the Paraná and Uruguay Rivers.
