The Large-scale Hydrology research group is part of the Institute of Hydraulic Research within the Federal University of Rio Grande do Sul, consisting of professors, researchers and students from UFRGS Postgraduate Course in Hydrological Resources and Environmental Sanitation, together with associates from other institutions.
The research group aims at improving knowledge on hydrology of large water basins and rivers, emphasizing in South America. Focus areas are:
- Development of hydrological models – We developed the large-scale hydrological model MGB; the large scale water quality model SIAQUA-IPH; and a waterbalance model for analysis of water rights and permits SAD-IPH.
- Flood forecasting and general hydrological forecasting – We develop streamflow forecasting techniques using quantitative precipitation forecasts and remote sensing precipitation estimates. We are now developing methods of ensemble flow forecasting.
- Analysis of hydrological change – Analysis of the effects of vegetation and land-use change on hydrology of large rivers. Analysis of impacts of climate change and variability; Mitigation of adverse effects of climate variability and extreme weather events such as flood and drought on rivers;
- Development of hydrodynamic models of rivers and lakes.
- Application of remote sensing data to hydrology – River altimetry; Remote sensing of precipitation and evapotranspiration.
- Development of geoprocessing tools applied to hydrology – Deriving useful information from Digital Elevation Models (DEM); Integration between Geographical Information Systems and hydrological models.
This website contains information on research carried out by members of the group, resulting publications and mathematical models developed by our group.
Some of the recent activities carried out by this group include:
- Development of a hydrological model for the Amazonas river basin.
- Development of a hydrological model of the Pantanal Mato-Grossense (wetland)
- Study of possible impacts of climate change on hydrology and hydropower production in Brazil.
