Activities in the operative hydrological forecasting:
- Hydrological warning and forecast (short, mean and long range, ice phenomena, high floods);
- Analysis of hazardous hydrological phenomena (high floods, drought, ice agglomeration).
- Implementation of forecasting methods at the Water Directions.
- Create and update the specific database.

  The main Information products are: daily hydrological bulletin, diagnosis and forecast along interior rivers, diagnosis and forecast (runoff and level) with an anticipation of 1 to 7 days along the Danube, Mures, Prut and Somes rivers, monthly and seasonal hydrological bulletin (updated every 10 days) for rivers and storage lakes, Informative bulletins and forecasts for hazardous hydrological phenomena (high floods, minimum runoffs, freezing phenomena), hydrological bulletins in view to ensure hydrological data exchange with neighboring countries, according to bilateral protocols enforced.

  The research in the domain of hydrological forecast is directed toward:
- Perfecting methodologies to elaborate hydrological forecasts through using, stochastic, deterministic mathematical models.
- Researches for coupling numeric weather forecasting models to rain-runoff forecasting models.
- Automatizing hydrological forecasting operative activity through Informatics procedures.
- Elaborating projects to modernize and automatize hydrological forecasting Information systems.
- Assessments on the evolution of very long-range river runoff, on the grounds of studies on the impact of climate changes on the runoff formation process, as well as determining their variability tendency.
- Researches on accidental pollution along rivers and elaboration of models to forecast pollutant waves.
- Modeling the runoff in urban areas.
