This paper is about the study of hydrodynamics of gabion models filled with aggregates for the coastal protection applications. The gabion walls usually constructed on coastal fronts for the protection of sea shore from high impact of ocean waves as well as erosion of soil from bottom of the gabion structure. Ocean wave strikes the coast line with very high hydrodynamic energy that can easily destroy it by bypassing the sand. The stepped gabions on coastal areas acts as better energy dissipating structure. These gabion wall reduces the impact of waves striking on it by dispersing the energy. The present experimental investigation assesses the velocity profiles of waves hitting on the gabion models placed in the hydraulic flume. The Acoustic Doppler velocimeter was used for determination of velocity profiles on upstream and downstream section of the model. The three stepped gabion wall models used in this study are rectangular gabion wall with mattress, curved gabion wall with front facing steps and curved wall with back facing steps. The velocity profiles were plotted for various wave conditions such as no wave condition, waves with frequency of 0.5, 0.75 and 1 Hz, at upstream and downstream locations of the wall. The velocity profile of rectangular gabion wall with mattress showed maximum energy dissipation compared to other types of gabion walls tested.
