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.

River brenta defence by controlled flooding
Author : Michele Ferri, Andrea Braidot
The way to tackle the even more frequent and harmful flood events, is to adopt efficient forecasting and risk prevention methods. This can be obtained only through a deep understanding of causes and dynamics involved in such events.The local Water Authority of North Eastern Italy, which is in charge of the planning and coordination of flood defence, water use and protection of water resources, has developed an accurate and robust of the hydrologic response model. The model, of the geomorphologic –MonteCarlo type, reproduces stochastic and real hydrographs and thereby the return period of peak flows and of any other feature of engineering interest, including shapes and volumes.The salient geomorphic features of the basin is recovered by digital elevation model while the land cover analysis is based on data from remote sensing.The main forecasting measures adopted in the regarding Plan for Brenta river hydraulic defence are presented: identification of the maximally effective gate operations for flood mitigation using the storage capacity Corlo reservoir, development of the hydrometeorological networks, real time interconnection of the hydro-meteorological control system and definition of the alerting procedures based not only on the notification of adverse weather conditions, but also on the knowledge of the land vulnerability according to established rainfall scenarios.
