Hydrological forecasting for tributaries to the hydro-power plants reservoirs in the Pelotas and Taquari Antas river basins based on quantitative precipitation forecasts
Start: 2009
Conclusion: 2012
Description:
The project had the following objectives: 1. Develop and implement a methodology for automatic verification of the quality of rainfall and runoff data in real time and for the assimilation of these data into a mathematical model of hydrological simulation adapted for streamflow forecasting. 2. Develop and implement an operational methodology for predicting flow in real time based on short-term quantitative prediction of rainfall obtained by meteorological models . 3. Develop and implement an operational methodology for seasonal streamflow forecasting (medium and long term) based on quantitative forecasting of precipitation obtained from the downscaling of seasonal climate predictions using a regional atmospheric model and hydrologic model. 4. Assess the quality of predictions of seasonal rainfall and short-term. 5. Assess the quality of predictions of flow obtained on the horizon seasonal and short term. 6. Study the use of these models for use in flood warning systems in the interest watersheds.

Results:
As a result of the project was developed an operational prototype streamflow forecasting systemfor the basins studied. This prototype is currently used for predicting streamflow in the HPPs in the region.
A summary of the results of the project was presented at the XI SRHN in the following publications (in portuguese):
