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.

Wave breaking and bottom friction over mildly sloping bed and bar in a new boussinesq wave model
Author :
In the present work a further advance of a previously presented Boussinesq model is introduced. This extension comprises of adding terms to the Boussinesq wave modelís equations, in order to incorporate the important phaenomena of wave breaking and bottom friction, which play an important role in wave transformation mainly in shallower waters and the surf zone. Wave breaking is implemented using the surface roller criterion. The enhanced model is applied in simulations of 1DH regular and random waves propagating over mildly slopping beds and submerged bars. The results of the simulations are compared to experimental data and those of MIKE21 BW, one widely acknowledged commercial wave model.
