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.

Effect of bed roughness prediction on morphodynamic modelling: application to the dee estuary (uk) and to the gironde estuary (france)
Author :
The bed roughness coefficient is identified as a highly sensitive parameter in morphodynamic models. Different methods can be used to prescribe the bottom roughness: the bed roughness can be either considered as a calibration coefficient or predicted as a function of the mean flow and sediment parameters. The effect of the friction coefficient is illustrated here, based on two applications: the large macro-tidal Gironde estuary, located in southwest France on the Bay of Biscay and the Dee estuary in Liverpool Bay on the Irish Sea. Both 2D hydrodynamic and morphodynamic models of the Telemac hydro-informatic system have been applied in a coupled way, to calculate the medium term bed evolution.
