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.

Waves produced by ship displacement on adjacent shoals and lateral basins of navigation canals
Author :
Navigation canals in estuaries are typically surrounded by ample natural shoals of much smaller depth and/or by semi-enclosed zones of reduced area. Even if the ship exhibits a relatively weak wake, the very same displacement of her submersed volume may have remarkable effects in the contiguous regions of the canal. The non-stationary currents created by the passing ship correspond to the superposition of a stationary flow field and a uniform motion (proportional to the ship velocity). The final resultant flow field, calculated via a simple two-dimensional model, and the consequent effects on the surrounding areas result to be dependent on the ship’s speed and the geometrical characteristics of the system canal /ship.
