IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

Predictability of short-term streamflow forecasts in australia
Author : T.C. Pagano, Q.J. Wang and P. Hapuarachchi
Many hydrologic research studies assume perfect knowledge of observed precipitation. This assumption does not hold in forecasting situations in which future precipitation may be partially or entirely unknown. This study used the Ensemble Streamflow Prediction procedure to generate 15 day ahead streamflow forecasts for many catchments in southeast Australia. While simulation performance of the GR4J model was very high for many catchments, forecast skill dropped rapidly with lead-time. Skill at longer lead-times was mostly due to the modelís ability to reproduce the hydrologic seasonal cycle. When seasonality is removed, almost none of the catchments had meaningful skill beyond 3 days lead-time.
